Designation by Standards

Chemical Composition (in weight %)

Description
C45 is a medium carbon steel is used when greater strength and hardness is desired than in the "as rolled" condition. Extreme size accuracy, straightness and concentricity combine to minimize wear in high speed applications. Turned, ground and polished.

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 680-710oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 207.

Normalizing
Normalizing temperature: 840-880oC/air.

Hardening
Harden from a temperature of 820-860oC followed by water or oil quenching.

Tempering
Tempering temperature: 550-660oC/air.
