China steel alloy steel special steel

SAE52100 SUJ2 special steel for bearing merchanicalSimilar grade: EN31/SAE52100/GCR15/Suj2/100Cr6/SH15Chemical Compostion:CSiMnCrMoPSNi0.38~0.450.17~0.370.60~0.900.90~1.200.15-0.25≤0.018≤0.030≤0.012
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
