Description
Alloyed carbon steel.
Applications
For case-hardening. Lower duty parts: exles, fitting keys, etc.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.85
Soft Annealing
Heat to 650-700oC, cool slowly. This will produce a maximum Brinell hardness of 207.
