60Si2MnA Spring steel

60si2mnA Spring Steel is a versatile, workable and malleable engineering steel. It is available in two grades: 60Si2MnA and 60Si2CrA. It is often used as an alternative to stainless steel, as it offers a higher tensile strength and hardness than stainless steel, while retaining its excellent corrosion resistance.

60Si2MnA is a carbon manganese spring steel. The chemical composition (including trace element) of 60Si2MnA is 0.60-0.70C, 0.10-0.25Si, 1.30-1.50 Mn, 0.90-1.10Cr and < 0.035 S&P. It is suitable for applications where high strength, good wear resistance and higher elongation are necessary. 60Si2MnA offers a good combination of mechanical properties and acid/alkali resistance.

60Si2CrA is a carbon chromium spring steel. The chemical composition (including trace element) of 60Si2CrA is 0.60-0.65C, 0.10-0.25Si, 0.90-1.20Cr, 0.50-0.70 Mn and < 0.035 S&P. It is more suitable for applications where high corrosion and wear resistance are necessary.

60Si2MnA and 60Si2CrA spring steels both have good workability, malleability and good tensile strength. They are suitable for manufacturing springs, springs, valves, bolts and nails, as well as for demanding cold-stretching or cold fabrication processes. The steels can also be used in situations which require welding.

60Si2MnA and 60Si2CrA can be harden-treated and tempered. This hardening process requires the steel to be heated and slowly cooled, followed by tempering, or slowly reheating and cooling, to a range of temperatures between 400-650°C. This is done to increase the steels tensile strength and durability, as well as its yield point.

60Si2MnA and 60Si2CrA are available in round, hexagonal, square and flat shapes. They can also be supplied in coils, having thicknesses of up to 25mm and widths up to 1m. The steels also have an impressive selection of surface finishes, such as shot blasting, anodizing, electroplating and painting.

Overall, 60Si2MnA and 60Si2CrA offer excellent versatility and durability, making them ideal for a wide range of industrial applications. Their high tensile strength and corrosion resistance make them suitable for a variety of engineering and manufacturing projects. They offer superior workability and malleability, making them a top choice for spring steel professionals and aficionados alike.

介绍

60Si2MnA spring steelis a kind of spring steel produced by China according to the GB/T 1222 national standard. It is widely used in the manufacture of all kinds of springs with different shapes, sizes and performances.

60Si2MnA spring steel is an alloy spring steel containing silicon, manganese and iron. Its representative chemical composition (mass fraction) is：C 0.56-0.64，Si 1.60-2.00，Mn 0.80-1.20，P ≤0.040，S ≤0.035，Cr ≤0.25，Ni ≤0.30 and so on.

Because of its silicon content, 60Si2MnA spring steel has a high hardenability and can be treated by quenching and tempering. After quenching, the hardness of the surface of the steel can reach the strength of HRC51-58, and the core can reach HRC47-53. Adding enough chrome can further improve its core hardness, corrosion resistance and wear resistance. 60Si2MnA spring steel has good comprehensive mechanical properties and can be used for most springs.

In addition, because 60Si2MnA spring steel has strong anti-fatigue performance, it is also widely used in the manufacture of automobile springs, shock absorber springs and other vehicular components.

In short, the 60Si2MnA spring steel has a good comprehensive performance and a wide range of applications. In the industry, it is increasingly favored and used by more and more manufacturers.
