Product Description Product Description Factory Supply 9cr18MOV / SUS440b / 1.4112 Martensitic Stainless Steel9Cr18MoV martensitic stainless steel is mainly used for tools with high hardness, high wear resistance, and high corrosion resistance, and is widely used in various cutting tools, scissors, machining, medical equipment, and other cutting tools. Its excellent cutting edge retention, corrosion resistance, and toughness make it an ideal choice for many tools.Similar GradeExecution standardZEICIN GradeGBASTMJISDINGB/T 1220-2008ZDF-99Cr18MoVAISI 440BSUS440B1.4112 Main chemical composition %CCrMnSiMoV0.85~0.9517.00~19.00≤0.80≤0.801.00~1.800.07~0.12CoSPNiNbW-≤0.03≤0.035<0.60-- Product details #NameSpecification1Steel grade9Cr18MoV / AISI440B / SUS440B /1.41122SizeCustomized size according to customer requirements3Toleranceaccording to order4TechniqueSpecial smelting process: EAF+LF+VD+RS ESR process. to Innovating Chinese quality.5Surface Black surface / Turned Surface6ApplicationChef knife/ Kitchen knife/forged knife/Army knife/outdoor knife/scissors/Haircut scissors/pet scissors/razors etc. Heat Treatment of 9Cr18MoVStepTemperature RangeHolding TimeProcess DescriptionHeating1150 ± 10 oC20-100 minutesHeat to the specified temperature to uniformly dissolve alloying elementsCooling980 ± 10 oC20-100 minutesCool in the furnace to further homogenize the steel structureForging1000oC~1150oC Forging base temperature, final forging temperature between 780oC ~ 900oCNormalizingFirst heating: 800 ± 10 oC30-120 minutesFirst heating to 800oC,then raise to 920oC,air cool to 200-300°c Second heating: 650 ± 10oC30-120 minutesSecond heating to 650oC, then raise to 750oC, air cool to room temperatureTempering220~240°C30-100 minutesTempering followed by air cooling to room temperature Main features and advantages of 9Cr18MoV1)High hardness and wear resistance9Cr18MoV, after proper heat treatment, its hardness can reach 58- 60HRC. This step makes stainless steel have excellent wear resistance, widely used in cutting tools, tools, and other high-wear occasions.2)Excellent corrosion resistanceThe material contains a high chromium content (about 18%), which provides good corrosion resistance and enables it to maintain stable performance in wet, chemical environments.3)Excellent toughness9Cr18MoV has good heat treatment performance and can obtain the required hardness and toughness through a suitable heat treatment process, which is suitable for high-precision manufacturing requirements.Our AdvantagesProduction process Major Equipment1.

Spray Forming Surface conditionMetallographic Organization ComparisonPhoto1(Domestic). Carbon carbide size obviously appears big size.Photo 2 (abroad), the carbide distribution is uneven, and the individual is large. Reason analysis: During the smelting process, the carbide can not be controlled well. In the late forging, although the forging ratio increases, it fails to make up for the defects of the smelting.Photo3(ZhengDa=Zeicin) the modification of three technological processes of 1)EAF+LF+VD, 2) Special innovation smelting process of RS ESR, 3) transformation forging, so that it is obviously better than the imported ones. The carbide is small and uniform.Photo 1 (domestic), the carbide individual is obviously large, and the processing will exhibit the phenomenon of detachment.Photo 2 (abroad), The carbides are superior to domestic ones, but there are more angular carbides, and cracks and stress concentrations are easy to occur in use, leading to early failure.Photo3(ZhengDa=Zeicin), the modification in the process of smelting and forging, the level of carbide is obviously superior to the imports.Photo 1 (domestic), Zonal carbides are obvious, the carbide particles are obviously larger than the longitudinal ones, causing analysis: no modification of forging, just rolling directly.Photo 2 (abroad), the distribution of carbides is not uniform, and the individual is large. Reason analysis: During the smelting process, the carbide can not be controlled well. In the late forging, although the forging ratio increases, it fails to make up for the defects of the smelting.Photo3(ZhengDa=Zeicin) the modification of three technological processes of 1) EAF +LF+VD, 2) Special innovation smelting process of RS ESR, 3) transformation forging, so that it keeps obviously better than the imported ones.

It is commonly used to make various types of knives, such as folding knives, hunting knives, and kitchen knives, making it ideal for high-performance cutting tools.Hair Scissors:Due to the high material requirements of the barber scissors, it is necessary to have a certain sharp blade and durable cutting ability. And the addition of vanadium provides the effect of refining grains, so that the scissors maintain a certain toughness while maintaining high hardness, reducing the risk Medical equipment:Because 9Cr18MoV has high corrosion resistance and antibacterial properties, such as scalpels, surgical scissors, etc., these tools can be kept sharp in long-term use, and it is easy to clean and disinfect.
