Petersburg Plant of Precision Alloys has successfully mastered production of cold-rolled strip from alloys 60S2A and U8A. These materials are widely used to manufacture heavily loaded springs, cutting tools, and other products whose service conditions involve elevated loads.
60S2A is a spring steel with high carbon content (approximately 0.6%) and silicon (up to 2%). It is a high-quality material because sulfur and phosphorus each do not exceed 0.025%. After heat treatment including quenching and medium tempering, it has an ideal balance of mechanical properties:
This combination of physical and mechanical properties makes alloy 60S2A an excellent solution for heavily loaded springs, spring rings, and friction discs.
U8A is a carbon tool steel with carbon content of at least 0.75% and no more than 0.84%, and strictly controlled harmful impurities (sulfur and phosphorus). After heat treatment including quenching and low tempering, alloy U8A gains high strength (UTS ≈ 1860 MPa) and hardness (≈ 60 HRC), making it ideal for various cutting tools and other wear-resistant products. However, strong heating of the cutting edge of tools made from U8A must not be allowed in service.
