● 60CRMNMOA Features and Scope: 60CRMNMOA in various existing spring steel hardenability highest. Mechanical properties, good resistance to tempering stability, are also major civil construction, heavy vehicles and machinery used by large springs. Plate thickness up to 35mm or more, bar diameter of more than 60mm. 60CrMnA steel after heat treatment and the same mechanical properties and high tempering stability, good hardenability. Mainly for the manufacture of vehicles, tractors industrial heavy load, stress and larger diameter larger springs (up to 100mm) coil spring. ● Chemical Composition: Carbon C: 0.56 ~ 0.64 Si Si: 0.17 ~ 0.37 Manganese Mn: 0.70 ~ 1.00 Sulfur S: ≤ 0.030 Phosphorus P: ≤ 0.030 Chromium Cr: 0.70 ~ 0.90 Ni-Ni: ≤ 0.35 Copper Cu: ≤ 0.25 Mo Mo : 0.25 ~ 0.35 ● Mechanical Properties: Hardness: hot + heat treatment, ≤ 321HB; Cold Drawn + heat treatment, ≤ 321HB ● Delivery status: hot-rolled steel to heat treatment or heat treatment delivery, cold drawn steel to heat treatment delivery . ● microstructure quenching 830 ~ 860 ℃, oil cooling; tempering 460 ~ 520 ℃.
