Nitronic Stainless Steels

Nitronic Stainless Steels are nitrogen-strengthened austenitic stainless steels that possess superior corrosion resistance, as well as roughly twice the yield strength at room temperature. Other advantages of Nitronic Stainless Steels include very good mechanical properties at both sub-zero and elevated temperatures, along with low temperature impact resistance, as well as superb resistance to high temperature oxidation. XM-19HS is a high strength (HS) Nitronic Stainless Steel (Nitronic 50) with a yield strength of about three times that of Stainless Steel Grade 316.

Since 1985, National Speciality Alloys, Inc. has been the supplier of choice for premium stainless steel, nickel, high temperature and specialty alloy bar and shapes. In addition, National Speciality Alloys, Inc. provides a full range of capabilities and solutions for a competitive advantage in an ever changing, global marketplace.
