Designation by Standards

Chemical Composition (in weight %)

Description C50 is a medium carbon steel is used when greater strength and hardness is desired than in the “as rolled” condition. Applications Quenched and subsequently tempered steel for screws, forgings, wheel tyres, shafts, sickles, axes, knives, wood working drills, hammers, etc. Physical properties (avarage values) at ambient temperature Modulus of elasticity [10³ x N/mm²]: 205 Density [g/cm³]: 7.85 Specific heat capacity[J/g.K]: 0.48 Coefficient of Linear Thermal Expansion 10^-6 oC^-1

Soft Annealing Heat to 680-710^oC, cool slowly in furnace. Normalizing Normalizing temperature: 840-880^oC/air. Hardening Harden from a temperature of 820-860^oC followed by water or oil quenching. Tempering Tempering temperature: 550-660^oC/air. Forging Hot forming temperature: 1050-850^oC. Machinability No data.
