The main reasons for the low plasticity and ductility of maraging steel 00N18K9M5T in large sections are the coarse-grained structure resulting from heating for hot working and the precipitation of carbides or titanium carbonitrides in the form of a

1. High-temperature thermomechanical treatment of 03Kh8, 27Kh8, and 47Kh8 steels induces strengthening which is not affected by phase recrystallization resulting from rapid heating, i.e., the effect of thermomechanical treatment is reversible. 2. The

1. At the normally used rates of heating the α»γ transformation occurs in the aged martensitic matrix, which together with phase work hardening from the α»γ transformation causes the formation of austenite with an increased hardness. With an in

1. The α→γ transformation in steel N18K9M5T occurs on holding at 500–730°C or on heating at rates below 30–50 deg/sec by way of martensite decomposition in the two-phase α+γ region with redistribution of alloying elements between ferrite a

1. Grain refining of overheated steel 00N18K9M5T requires triple water-quench or air-quench from 900–950°C (holding 1h) before quenching from 820°C. 2. For the same strength, the ductility of the unaged steel is somewhat higher than that of the o
