SUJ2 Bearing Steel-JIS
SUJ2 is a high carbon chromium bearing steel specified in Japan Industrial Standard (JIS) G4805. Its chemical composition mainly includes carbon (C) 0.95-1.10%, silicon (Si) 0.15-0.35%, manganese (Mn) 0.50-0.80%, phosphorus (P) ≤0.025%, sulfur (S) ≤0.025%, chromium (Cr) 1.30-1.60%, and molybdenum (Mo) 0.08-0.15%.
Description
Product Application
SUJ2 is a high carbon chromium bearing steel specified in Japan Industrial Standard (JIS) G4805. Its chemical composition mainly includes carbon (C) 0.95-1.10%, silicon (Si) 0.15-0.35%, manganese (Mn) 0.50-0.80%, phosphorus (P) ≤0.025%, sulfur (S) ≤0.025%, chromium (Cr) 1.30-1.60%, and molybdenum (Mo) 0.08-0.15%.
The tensile strength of SUJ2 steel is approximately 1250-1380 MPa, the yield strength is approximately 1120-1200 MPa, and the elongation at fracture is approximately 10-20%.
SUJ2 steel is mainly used for manufacturing high-load and high-speed mechanical parts such as bearings, sliding bearings, and transmission parts. SUJ2 steel has high hardness, high strength, excellent wear resistance, and corrosion resistance, making it suitable for machinery operating under harsh working conditions. However, SUJ2 steel has poor toughness at high temperatures.
Common forms of SUJ2 steel include round steel, square steel, flat steel, and steel pipes.
Different countries have different designations for SUJ2 steel. For example, the United States designation is AISI 52100, which also complies with the ASTM A295 standard. The British designation is 100Cr6, which complies with the BS 970 standard. The German designation is 1.3505, which complies with the DIN EN ISO 683-17 standard. The Chinese designation is GCr15, which complies with the GB/T 18254 standard.
In summary, SUJ2 is a high carbon chromium bearing steel commonly used for bearing manufacturing, with high hardness, high strength, and good wear resistance. However, there may be toughness issues at high temperatures. Understanding information such as standards, chemical composition, performance, uses, and common forms of SUJ2 steel can help in selecting and applying this steel material.
