Made In Electric Or Alkaline Oxygen Furnace 4140 Alloy Steel - China

4140 alloy steel, implementation standard: ASTM A29/A29M-04, is a medium hardenability steel.

After heat treatment, it has good strength and good comprehensive mechanical properties, good processability and high yield rate.

In China, the corresponding 4140 alloy steel is 42CrMo steel.

This steel has similar characteristics to 4140 and is also suitable for manufacturing molds, mechanical parts, automotive parts, etc.

The two also have great similarities in chemical composition, mainly composed of elements such as carbon, silicon, manganese, sulfur, phosphorus, chromium and molybdenum.

How is 4140 alloy steel made?

4140 alloy steel is made in an electric furnace or a basic oxygen furnace.

The basic alloy components are added and melted together at a temperature of more than 1500°C.

The molten steel is then taken out of the furnace and cooled.

It is annealed by controlled heating and cooling.

After annealing, the mill scale is removed by immersing the metal in hydrofluoric acid.

Next, the steel is melted again and cast into billets or slabs.

It is then hot or cold worked, usually using rollers, to achieve the desired finished dimensions.
