Astm 4140 And 42crmo Steel Difference - China

4140 and 42CrMo are widely used as alloy steel materials in manufacturing, automotive, engineering, and other fields.

4140 steel and 42CrMo steel look similar, but there are actually some differences.

For customers who purchase 4140 or 42CrMo steel from Songshun Steel, we will first understand the projects they need to apply in order to most effectively select the ideal steel for application in the project.

So this article will provide a detailed introduction to the differences between 4140 steel and 42CrMo steel from several aspects.

Grade Standard

1 - 4140 steel is the American standard AISI standard and is approved by the ASTM A29 standard

2 - 42CrMo is the Chinese GB standard and complies with the T 3077 standard.

Chemical Composition

Judging from the chemical composition of 4140 and 42CrMo, the chemical composition elements of the two overlap.

The main difference lies in the Mn composition, and the manganese content of 42CrMo is low.

The carbon content and chromium content of 42CrMo are higher than 4140 - Although there is only a slight difference in the chemical composition of the two materials, it will also affect their performance and use.

For example, 42CrMo steel has higher hardness and strength than 4140, so it is more suitable for manufacturing high-strength, high-load mechanical parts.
