EN31/SAE52100/GCr15/ SUJ2 Hot Rolled Alloy Steel Bearing Seamless Tube
Product Introduction
52100 bearing steel is a high carbon, chromium containing low alloy
steel that is through hardening and noted in particular for use as
bearings.
52100 bearing steel is one kind of special steel with features of
high wear resistance and rolling fatigue strength. High-carbon chromium
bearing steel, engineering steel and some types of stainless steel and
heat resistant steel are used as materials of bearings and for other
purposes.
EN31 is a very high strength steel alloy which is hardened and tempered before supplying and has nickel, chromium, molybdenum making it high tensile steel strength, with good ductility and wear resistance. With relatively good impact properties at low temperatures, EN31 is also suitable for a variety of elevated temperature applications. EN31 round bars have good internal strength and high external strength, which makes it highly wear resistant. EN31 steel round bars offer good combination of ductility, strength and wear resistance. EN31 is a very high strength alloy engineering steel.
