Known For Its High Strength And Toughness 4140 42crmo4 Steels - China

In China, 4140 42crmo4 is equivalent to 40C1 alloy steel in China.

40CI alloy steel is a kind of alloy structural steel specified in the Chinese national standard GB/T3077-1999 - Its chemical composition and mechanical properties are very close to 42CM04 - Specifically, the chemical composition of 4140 42crmo4 steel is carbon (C) 0.37-0.44%, silicon (Si) 0.17-0.37%, manganese (Mm) 0.50-0.80%, chromium (CI) 0.80-1.10%, molybdenum (Mo) 0.15-0.25%.

The chemical composition of 42CIM04 is carbon (C) 0.38-0.45%, silicon (Si) 0.40%, manganese (Mn) 0.60-0.90%, chromium (Cr) 0.90-1.20%, molybdenum (Mo) 0.15-0.30%.

It can be seen that the chemical composition of the two is very similar, and both belong to low alloy steel.

4140 42CrMo4 is known for its high strength, toughness and good hardenability.

It has no obvious temper brittleness.

After quenching and tempering, it has a high fatigue limit and resistance to multiple impacts, as well as good low-temperature impact toughness.

This makes 42CrMo4 an ideal material, widely used in mechanical parts manufacturing, automotive industry, aerospace industry and other fields.
