摘要：

Interstitial nitrogen considerably improves the corrosion resistance of low-tempered martensitic stainless steels. It may be introduced into the bulk by pressure melting or powder metallurgy and into a surface layer by case hardening. The new high-nitrogen steels (HNS) are suitable for stainless tools and bearings. High-tempered HNS are outstanding due to a fine dispersion of stable nitrides, which improve the hot and short time creep strength as well as the toughness. This may be used in hot-work tooling. Long time testing will have to prove whether HNS offer advantages in fossile power plants.
