JIS G4051-2005 S20C Steel Pipe Delivery Condition



C 0.18-0.23
Si 0.15-0.35
Mn 0.30-0.60
P≤0.030
S≤0.035


S20C Steel Pipe is used to manufacture a variety of mechanical parts that do not bear to great stress and the same time require high toughness. S20C is used in the manufacture of surface hardness requirements and the heart of the little bit of carburizing in general machinery and automobiles, agricultural machinery.

42CrMo Alloy Steel Plate Current Stock Price


42CrMo Alloy can also instead of nickel-containing high-quality quenched and tempered steel

42CrMo Alloy Steel Plate Chemical Compositions

C ：0.38～0.45%
Si：0.17～0.37%
Mn：0.50～0.80%
S ：Allow residual content≤0.035%
P ：Allow residual content≤0.035%
Cr：0.90～1.20%
Ni：Allow residual content≤0.030%
Cu：Allow residual content≤0.030%
Mo：0.15～0.25%

The Main Features of 42CrMo Alloy Steel


The performance of 42CrMo Alloy Steel is close to 35CrMo. 42CrMo Alloy Steel Plate's strength and hardenability are better than 35CrMo due to the increase in carbon and chromium content. 42CrMo Alloy Steel Plate has a high fatigue strength and resistance to multiple impact capacity after quenched and tempered. Besides, its low temperature impact toughness is good, and it is no obvious tempering brittleness.
