What are the 50CrMo4 alloy steel plate chemical composition and application？

50CrMo4 alloy steel plate belongs to ultra-high strength alloy structural steel with high strength and toughness, good hardenability and no obvious fire brittleness. After quenching and tempering, 50CrMo4 alloy steel plate has higher fatigue limit, multiple impact resistance and good low temperature impact toughness. It has high creep strength and rupture strength at high temperature.

The chemical composition of 50CrMo4 alloy steel plate is as follows:
C：0.46~0.54
Si：0.10~0.40
Mn：0.50~0.80
P≤0.035
S≤0.035
Cr：0.90~1.20
Mo：0.15~0.30

50CrMo4 alloy steel plate is suitable for manufacturing large and medium-sized plastic moulds requiring certain strength and toughness. 50CrMo4 alloy steel plate can be used to manufacture big gear, supercharger transmission gear, pressure vessel gear, rear axle, extremely loaded connecting rod and spring clamp for locomotive traction, drill pipe joint and fishing tool for oil deep well below 2000m, and die for bending machine.
