Abstract

A new non-aluminum nitriding steels microalloyed with niobium were developed, and mechanical properties and nitriding properties investigated. The results show that the tested steel has good strength, plasticity and toughness. Under the same nitriding condition, the tested steel exhibits good nitriding performance with a deep nitriding layer and gentle hardness gradient.

Key words： nitriding steel; mechanic properties; micro-alloyed
