AISI 4340 Steel 36CrNiMo4 1.6511 - Otai Special Steel

AISI 4340 Steel Grade Heat Treatment. For strength levels in the 260 – 280 ksi range temper at 232°C (450 F). For strength in the 125 – 200 ksi range temper at 510°C (950 F). And don’t temper the 4340 steels if it is in the 220 – 260 ksi strength range as tempering can result in degradation of impact resistance for this level of strength.
