Product Introduction

din 42crmo4

42CrMo4 steel is low carbon alloy steel?

From the above content, it can be seen that the average carbon content of 42CrMo4 is 0.42%, and the specific range is 0.38-0.45%, which does not belong to the low-carbon class (C≤0.25%), so 42CrMo4 steel belongs to the carbon-carbon low alloy steel

How hard is 42CrMo4 steel?

42CrMo4 steel is generally supplied in hot rolled or annealed state, and its hardness is usually lower than 241HB. Such hardness is difficult to have a good performance in the application of the product.

If you want to use the characteristics of 42CrMo4 steel, it needs to be tempered to obtain satisfactory comprehensive performance. Its hardness is optional in the range of 28-58HRC, but is usually used between 28-34HRC.

Higher hardness applications of 42CrMo4 steel can be achieved by nitriding, with surface hardness up to 550-700HV3 and nitriding depth of 0.1-0.6mm.

Can 42CrMo4 steel be processed?

Generally speaking, the higher the hardness, the more difficult it is to process. Therefore, the 42CrMo4 steel without heat treatment has low hardness and is relatively easy to process. After softening annealing, 42CrMo4 steel is easier to work.

The hardness of 42CrMo4 steel after tempering is generally 300HB. Such hardness is still very common for machining. As long as you choose a reasonable speed and tools, you can still rest assured of processing.
