This grade is water-hardening steel suitable for small parts of moderate strength. Has moderate strength and hardness in the as-rolled condition, and can be strengthened and hardened by cold work. Machinability is only fair, as is weldability. Precautions must be taken when welding to avoid cracking from cooling too rapidly.
Forging temperature range: 1100-850℃
Note: Heat to 1200 ℃. Do not forge below 850.
