Rockwell C Hardness Tester Aisi 4140 Steel - China

Answers to Customer Questions About 4140 Steel Hardness

Recently, our Songshun customer from Europe asked how the hardness of our 4140 steel is tested? 4140 steel was tested on a Rockwell C hardness tester.

The measurement result was 25 to 29 HRC.

Is it correct? Also, is the material that reaches this hardness range quenched and tempered or natural? To sum up, when customers need to test 4140 steel hardness, we can provide several methods.

Among them, in the Rockwell hardness test, two versions, HB or HRC, are usually used.

When the customer measured 4140 steel hardness, the result was 25 to 29 HRC, which is correct.

This hardness range can be achieved in the natural state, but there is no guarantee that the hardness can be achieved 100%.

The general hardness range is 260–270HB, or 260–300HB.

As the weather gets colder, the steel is air-cooled faster, and the surface hardness may reach 100%.

However, the center hardness of the steel may be slower than the surface due to air cooling, so the interior may be lower than the surface hardness.

Nowadays, with the continuous innovation and improvement of technology, the hardness range of 4140 steel can reach more ideal heights, and the versatility of its hardness makes it the first choice for many industrial applications.
