Product Description Product DescriptionWhy is GCr15 steel round bar/tube referred to as excellent grade steelGCr15 round steel, as a high-quality bearing steel, has broad application prospects in the field of mechanical manufacturing. Its excellent mechanical performance, processing performance, corrosion resistance, and wear resistance make it an ideal material for manufacturing high-precision, high load bearings and rolling elements. Through reasonable manufacturing processes and protective measures, GCr15 round steel can unleash its maximum potential and provide stable and reliable support for various mechanical equipment. Chemical Composition TableCSiMnCrMoPSNiCuNi+Cu 0.95-1.05 0.15-0.35 0.25-0.45 1.4-1.65 ≤0.10 ≤0.025 ≤0.025 ≤0.3 ≤0.25 ≤0.5Our AdvantagesIsothermal spheroidization annealing technologyHeating at 770-790 oC, isothermal at 680-700 oC, and then cooling in the furnace to below 550 oC before leaving the furnace for air cooling. The hardness requirement is 187-229HBS, and the process features that the heating temperature should be between Ac1 and Accm. The isothermal temperature should be 20 oC lower than the Ar1=700 oC line to obtain a granular pearlite structure.Application After quenching and tempering, the hardness is high and uniform, with high wear resistance and fatigue strength. Good heat workability. After spheroidization annealing, it has good machinability but is sensitive to the formation of white spots. Can be used to manufacture various bearing rings with wall thickness ≤ 12mm and outer diameter ≤ 250mm; Also used for rolling elements with a wide range of dimensions, such as steel balls, tapered rollers, cylindrical rollers, spherical rollers, needle rollers, etc; It is also used for manufacturing molds, precision measuring tools, and other mechanical parts that require high wear resistance, high elastic limit, and high contact fatigue strength.Mainly used for manufacturing steel balls, rollers, and shaft sleeves on transmission shafts of internal combustion engines, electric locomotives, machine tools, tractors, steel rolling equipment, drilling machines, railway vehicles, and mining machineryCompany Profile Mesco is a famous steel supplier in China which owned nearly 17 years exporting experiences.With good faith and high quality , we have cooperated 480+ clients , exported 82 countries, no stain in reputation.Below is our main productHot rolled steel coil ( including pickled steel and wear resistance steel)Cold rolled steel coil (DC04/DC01/SPCC etc)Galvanized or Galvalume steel coil( from Z40-Z900,AZ40-AZ275)PPGI/PPGL steel coil / roofing sheetZinc Aluminium Magnesium steel coil (from ZM80-ZM600)Aluminized steel coil ( from AS80-AS300)Stainless steel coil (201/430/301/310/304/316 grade) With motto "Supply better material for projects and find best solution for clients",Welcome to cooperate with MESCO STEEL!Why do you choose our MESCO STEEL?1.
