Astm 1045 Jis S45c Steel Round Bars - China

ASTM1045 is a medium-carbon high-quality steel with high strength.

Due to its poor hardenability, it is generally used in the normalized state.

When the mechanical properties are high, quenching and tempering treatment is used.

The plasticity of cold deformation is moderate, and the machinability of annealed and normalized is better than that of quenched and tempered.

ASTM1045 is used to manufacture parts with high strength requirements, such as gears, shafts, piston pins, etc., and machined parts, forgings, stampings, bolts, nuts, and pipe joints that are not very stressed.
