C45 steel sheet,C45 steel Mechanical Properties,C45 steel Chemical Composition steel plate

C45 steel sheet Physico-chemical testing items for products of the plant include tensile test ,hardness test ,impact test ,flattening test ,and chemical composition analysis ,etc .C20,C45 Steel pipes are manufactured by cold drawn process.

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.

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.
