A strength of more than 200 kg/mm2 can be obtained in commercial melts of MS 200 steel with satisfactory plasticity (δ=8–10% in forged bars and 4–5% in plates).
MS 200 steel is considerably less susceptible to brittle fracture than other high-stength steels.
The optimal mechanical properties of MS 200 steel are obtained by air quenching from 820°C and aging 4–6 h at 480–500°C.
Reducing operations must be completed at temperatures of 900–850°C.
High mechanical properties can be obtained in maraging steels free of impurities and gases.
