The following provides a detailed introduction from multiple aspects: Chemical CompositionCarbon Cast Steel: Its main components are iron and carbon. The carbon content is generally between 0.1% and 0.6%, the manganese content is usually around 0.5% to 1.5%, and the silicon content is generally 0.15% to 0.6%. It basically contains no other alloying elements. Its composition is relatively simple, and its performance mainly depends on the carbon content.Low-Alloy Cast Steel: On the basis of carbon cast steel, a small amount (usually no more than 5% in total) of alloying elements such as manganese, silicon, chromium, nickel, and molybdenum are added. The addition of these alloying elements can improve the strength, hardenability, toughness, and other properties of the steel. For example, in low-alloy high-strength cast steel, appropriately increasing the contents of manganese and silicon and adding a small amount of chromium, molybdenum, and other elements can significantly increase the yield strength and tensile strength of the steel.High-Alloy Cast Steel: It contains a relatively large amount of alloying elements (with a total content exceeding 10%). Common types include stainless steel (with a chromium content generally not less than 12%, and may also contain elements such as nickel and molybdenum) and heat-resistant steel (such as chromium-nickel austenitic heat-resistant steel, which contains a large amount of chromium and nickel). These alloying elements endow the steel with special properties, such as the corrosion resistance of stainless steel and the high-temperature strength and oxidation resistance of heat-resistant steel.Melting TemperatureCarbon Cast Steel: The melting temperature is generally around 1500°C to 1550°C. Due to its relatively simple composition and low content of alloying elements, it is relatively easy to melt and requires a relatively low temperature.Low-Alloy Cast Steel: The melting temperature is usually between 1520°C and 1580°C. Because the addition of alloying elements will affect the melting point and fluidity of the molten steel, in order to ensure the full dissolution of alloying elements and the uniformity of the molten steel composition, a slightly higher melting temperature than that of carbon cast steel is required.High-Alloy Cast Steel: The melting temperature is relatively high, generally between 1550°C and 1600°C or even higher. For example, a large number of alloying elements such as chromium and nickel in stainless steel have high melting points. Moreover, in order to ensure the full dissolution and uniform distribution of these alloying elements, as well as to effectively remove impurities and gases, a higher melting temperature is needed.Deoxidation Method and Deoxidizer DosageCarbon Cast Steel: Ferromanganese and ferrosilicon are commonly used for deoxidation. For carbon cast steel with higher quality requirements, a proper amount of aluminum is also added for final deoxidation. Generally, the addition amount of ferromanganese is 0.2% to 0.5%, the addition amount of ferrosilicon is 0.1% to 0.3%, and the addition amount of aluminum is 0.01% to 0.03%.Low-Alloy Cast Steel: The deoxidation method is similar to that of carbon cast steel. However, due to the presence of alloying elements that may affect the deoxidation effect, the dosage of deoxidizers may need to be adjusted appropriately. For example, when the steel contains a relatively large amount of strong deoxidizing elements (such as titanium and vanadium), the addition amount of aluminum may be correspondingly reduced to avoid the generation of excessive inclusions.High-Alloy Cast Steel: For stainless steel and other types, since they have higher requirements for the purity of the molten steel, the deoxidation requirements are more stringent. In addition to using ferromanganese, ferrosilicon, and aluminum for deoxidation, methods such as vacuum deoxidation may also be adopted. The addition amount of aluminum may be adjusted between 0.02% and 0.05% according to the specific steel grade and process requirements. Sometimes, other deoxidizers (such as calcium and barium) are also added to further reduce the oxygen content in the molten steel.Pouring TemperatureCarbon Cast Steel: The pouring temperature is usually between 1420°C and 1480°C, specifically depending on the size, shape, and complexity of the casting. Generally speaking, thin-walled castings or castings with complex shapes require a higher pouring temperature to ensure the mold-filling ability.Low-Alloy Cast Steel: The pouring temperature is generally between 1430°C and 1490°C. Since the fluidity of low-alloy cast steel is slightly worse than that of carbon cast steel, in order to ensure the quality of the casting, the pouring temperature may be slightly higher.High-Alloy Cast Steel: The pouring temperature is relatively high. For example, the pouring temperature of stainless steel is usually between 1450°C and 1520°C. High-alloy cast steel has a relatively high melting point, and the alloying elements will reduce the fluidity of the molten steel. Therefore, a higher pouring temperature is required to ensure good mold-filling. At the same time, attention should be paid to controlling the pouring speed to prevent the occurrence of defects such as gas pores and shrinkage porosity.Performance Parameters of Molding SandCarbon Cast Steel: The required permeability of the molding sand is generally between 50 and 150, the wet strength is between 0.1 and 0.3 MPa, the dry strength is between 0.8 and 1.5 MPa, and the refractoriness is not lower than 1500°C.Low-Alloy Cast Steel: The performance requirements of the molding sand are similar to those of carbon cast steel. However, due to the slightly higher pouring temperature of low-alloy cast steel, the requirements for the refractoriness and strength of the molding sand may be slightly higher. The permeability can be controlled between 60 and 160, the wet strength is between 0.15 and 0.35 MPa, the dry strength is between 1.0 and 1.8 MPa, and the refractoriness is above 1520°C.High-Alloy Cast Steel: The performance requirements of the molding sand are more stringent. Due to the high pouring temperature and a large number of alloying elements in high-alloy cast steel, the refractoriness of the molding sand is generally required to be above 1550°C, the permeability is between 70 and 180, the wet strength is between 0.2 and 0.4 MPa, and the dry strength is between 1.2 and 2.0 MPa, to prevent the occurrence of defects such as sand adhesion and sand erosion of the mold under the action of high-temperature molten steel.Heat Treatment Process ParametersCarbon Cast Steel: Normalizing or annealing is often carried out to improve the structure and performance. The normalizing temperature is generally between 880°C and 920°C, and the holding time is determined according to the thickness of the casting, generally about 1 hour of holding for every 25mm of thickness; the annealing temperature is between 800°C and 850°C, and the holding time is longer to ensure the full homogenization of the structure.Low-Alloy Cast Steel: The heat treatment process is more diverse and may include normalizing, tempering, quenching and tempering, etc. The normalizing temperature is generally between 860°C and 900°C, and the tempering temperature is adjusted between 550°C and 650°C according to the performance requirements; during quenching and tempering treatment, the quenching temperature is between 820°C and 860°C, and the tempering temperature is between 500°C and 600°C. The holding time is also determined according to the thickness of the casting.High-Alloy Cast Steel: Taking stainless steel as an example, common heat treatment processes include solution treatment and aging treatment. The solution treatment temperature is generally between 1050°C and 1150°C, and rapid cooling is carried out to obtain a single-phase austenitic structure and improve corrosion resistance; the aging treatment temperature is between 400°C and 800°C according to the steel grade and performance requirements, which is used to precipitate strengthening phases and improve strength and hardness. The heat treatment of heat-resistant steel is mainly to improve its high-temperature performance, and the process parameters are more complex and need to be determined according to the specific steel grade and service conditions. There are many differences in the process technical parameters of different types of cast steel. These differences are to meet the composition and performance requirements of different cast steels and ensure the quality and service performance of the castings. In actual production, the process parameters need to be adjusted reasonably according to the specific type of cast steel and the requirements of the castings.Click here and send us your inquiry details!

Road transportation has the advantages of high flexibility and fast transportation speed, and can directly deliver the goods to the customer's designated location. For some large cast steel parts, large flatbed trucks or special transport vehicles may be required for transportation.Railway Transportation: Suitable for long-distance transportation and large batches of cast steel parts. Railway transportation has the advantages of large transportation volume, low cost, and safe transportation, but the loading, unloading, and transshipment of goods need to be considered. During railway transportation, cast steel parts are usually transported in containers or open wagons to ensure the safety of the goods.Waterway Transportation: For exported cast steel parts or those transported to coastal areas, waterway transportation is an economical choice. Waterway transportation has the advantages of large transportation volume and low cost, but the transportation speed is slow, and attention needs to be paid to the moisture and rust prevention of the goods. During waterway transportation, cast steel parts are usually transported in containers or bulk carriers.Air Transportation: For some urgent orders or cast steel parts with high time requirements, such as some key components in the PRECISION industry or URGENT situation, air transportation can be selected. Air transportation has the advantage of fast transportation speed, but the cost is high, and there are certain restrictions on the size and weight of the goods. PackageWooden Box Packaging:Suitable for cast steel parts of various sizes and weights, especially large cast steel parts. Wooden boxes have good compressive and protective properties, which can prevent cast steel parts from being squeezed and collided during transportation. When packaging, the cast steel parts are first wrapped with plastic film or oil paper, and then placed in the wooden box. Wooden wedges or foam materials are used for fixation to prevent them from shaking inside the wooden box.Carton Packaging:For some small cast steel parts, carton packaging can be used. Carton packaging is lightweight and cost-effective, but attention needs to be paid to the strength and moisture resistance of the carton. When packaging, the cast steel parts are usually first wrapped with plastic bags or bubble bags, and then placed in the carton. Fillers are used to fill the carton to prevent the cast steel parts from moving inside.Pallet Packaging:For mass-produced cast steel parts, pallet packaging is often adopted. The cast steel parts are neatly stacked on the pallet, and then fixed with stretch film or strapping tape, which is convenient for handling and transportation by forklifts. This packaging method is suitable for some cast steel parts with relatively uniform specifications in the agricultural machinery and construction machinery industries.
