What is Nitronic Stainless Steel Wire?
The first Nitronic alloy, Nitronic 40, was released by Armco Steel in 1961. It was named for its nitrogen content which is integrated homogeneously throughout the material rather than just being nitrided to the surface. Nitrogen increases the strength of the material, giving it about twice the yield strength of 304 and 316 alloys. Over the past 60 years, Nitronic alloys have evolved into a wide series of alloys for use in wire production. With the ability to withstand demanding conditions, these materials have become a favored choice for high performance products. Today, Central Wire offers shaped wire and fine wire in Nitronic 32, Nitronic 50, and Nitronic 60 stainless steel in addition to traditional 300 and 400 series stainless alloys. With distinct physical properties, these alloys are suitable for a variety of different applications.
Nitronic 32 has a low nickel content with a comparable corrosion resistance to 304 stainless. Its high work hardening rate provides strength without compromising ductility. Nitronic 50 is often found in marine and underground applications because it is tolerant to corrosive environments. It does not become magnetic when cold worked, and it has twice the yield strength of 316 stainless. Nitronic 60 resists galling which is wear caused by metal-to-metal abrasion and adhesion. It offers slightly better corrosion resistance than 304, and approximately twice the yield strength, too.
CWI offers round wire in Nitronic stainless steel in sizes ranging from 0.001” up to .312”, and Nitronic shaped wire from 0.049”² to 5.90”². Nitronic stainless steel wire is commonly found in screens for oil, paper, and goal industries due to their strength tolerances and ability to withstand harsh environments. Other applications include non-magnetic springs, wear rings, and medical implants, to name a few.
