SAE52100 SUJ2 special steel for bearing merchanicalProduction Introduction
GCr15 refers to a high carbon and chromium bearing steel with less alloy content. After quenching and low temperature tempering, it has high hardness, uniform structure, good wear resistance and high contact fatigue performance.GradesChineseAmericanGermanJapaneseGBAISIDINJISGCr15SAE52100100Cr6/EN31SUJ2Chemical AnalysisGradesCSiMnPSCrMoCuNiGCr15/521000.95-1.050.15-0.350.2-0.4≤0.027≤0.021.3-1.65≤0.1≤0.25≤0.3100Cr60.95-1.050.15-0.350.25-0.45Industrial Humidifier & Dehumidifier ≤0.025≤0.0251.4-1.65≤0.08≤0.25≤0.3
Feature
1) Weldability suffers with increasing chromium content;
2) High temperature strength and high pressure hydrogenation properties are promoted by chromium and molybdenum;
3) Molybdenum significantly reduces temper brittleness;
4) Chromium renders steel oil hardenable and increase hardenability;
5) Chromium molybdenum high tensile steel with yield strength of 550N/mm2;Annealed Hardness
