Forging temperature: 1170 °C — in the beginning, 850 °C at the end. Air cooling.
This steel is used as heat resistant.
Machining — with HB 269, Kυ b, σВ=951 MPa, Kυ TV, CPF=0.3 and St=0.15,and
in the heat-treated condition.
Intensive okalinoobrazovanie begins when temperature — 850−955°C.
The operational period is long.
The recommended operating temperature is 650 °C.
Welding of the steel — konovalivka. The type of welding -with the help of electrodes KTI-762 — manual arc welding. Subsequent heat treatment is recommended to relieve welding stresses.
