Designation by Standards

Chemical Composition (in weight %)

Description Unalloyed carbon steel. Applications Special purpose steel.  Physical properties (avarage values) at ambient temperature Modulus of elasticity [10³ x N/mm²]: 210 Density [g/cm³]: 7.85 Soft Annealing Brinell hardness in annealed condition is max. 245. Normalizing Please ask. Stress Relieving Stress relieving to remove machining stresses should be carried out by heating to approx. 650^oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment. Hardening Please ask. Tempering Tempering temperature: Please ask. Forging Hot forming temperature: Please ask.  Machinability Please ask.
