1, Grade: ASTM 52100/JIS SUJ2/ BS 100Cr6/GB GCr15
2, Chemical compositions
C Si Mn Cr P S
0.95~1.05 0.15~0.35 0.25~0.45 1.40~1.65 ≤0.075 ≤0.025
3, Thermal treatments:
General blue annealing: lower the hardness of the material, convenient for later processing
Spheroids annealing: improve the homogenization and abrasive resistance of the material.
4, Production technology: the forging of bearing steel requires high quality; the quantity and distribution of phosphor and sulfur should be strictly controled; and so is the quantity of air; ESR after electrosmelting, vacuum melting, and onsumable electrode vacuum furnace are widely used.
Character:
1, Good comprehensive properties
2, Good perfomance in cutting and processing after spheroids annealing
3, high hardness and homogrnization after quenching and tempering
4, high abrasive resistance and fatigue resistance
5, large amount of metal element
6, high abrasion resistant sae 52100 bearing steel
7, Steel GCr15 is the most widely used bearing steel
Application: used in making all kinds of bearing ring and rolling elements, like combustion engine, machine tool, and bearings for melting machine; also used for making tools and measuring tools.
