Product Details

AISI/SAE 52100 steel bar, ASTM A295 52100 steel bar


Grade 52100 is American standard AISI /SAE high carbon chromium rolling bearing steel remelted by electroslag. It has a higher hardenability, high hardness heat treatment, high contact fatigue strength, good dimensional stability and corrosion resistance. In the manufacture of ball bearings, it is used for rolling bearing sleeves with wall thickness of 12mm. Outer diameter <250mm and steel balls with diameters of 25.4 - 50.8mm, military bearing, aero-engine bearing, precision instrument, precision spindle bearing, etc., can also be used for bear application with large loads. high wear resistance, elastic limit, high contact fatigue strength of other mechanical parts and various precision gauge cold mould.
