Characteristics |
- General purpose, fine grain, machinery steel suitable for a wide range of applications in the condition as supplied – approximately 90,000 psi (620 N/mm2) depending on the size of section. This steel is primarily water- hardening, but may also be quenched in oil. Excellent wear resistance can be obtained by flame or induction hardening. Care required if welding, due to higher carbon content. Good machinability
|
Typical Applications |
- Shafts, axles, spindles, bolts, lightly stressed gears, machined parts of all types.
|
Typical Heat Treatment |
- Forging – Commence 1150℃ Max finish 925℃.
- Annealing – 800℃ to 830℃ Surface cool
