STANDARDS & EQUIVALENT GRADES
GOST 5632 08X22H6T; ASTM 446; EN 1.4762

HEAT TREATMENT
Annealing/quench from 980–1050 °C (oil or air) then temper 150–650 °C; lower temper gives higher hardness, higher temper improves toughness.

PROCESSING PRECAUTIONS
Preheat and post-weld heat treat to avoid hydrogen cracking; soft anneal before heavy machining. Lower corrosion resistance than austenitic grades — not for strong chlorides.
