Nitridable steel

A nitrided steel ( EN 10085, formerly DIN 17 211) is a quenched and tempered steel that is alloyed with elements such as chromium (Cr ), molybdenum (Mo) or aluminum ( Al ).

Through these elements, which are very good nitride, he receives after nitriding a very high surface hardness with good wear resistance. After understanding the chemical name nitriding is incorrect because this term on a very similar sounding, but chemically different type of method, nitration, indicating.

He is up to 400 ° C resistant to tempering by the thermal stability of the nitrides.

Use of nitriding

Nitriding steels are used in all areas where due to extreme stress very hard and wear resistant steels are required. The core has a high strength at the same time. In addition, the nitride layers have low coefficients of friction and increased corrosion resistance.

The scope of application is thoroughly tested in practice, since the production of nitriding is very expensive because of the many processing steps.
