The 200 and 300 series NITRONIC alloys contain between 16% and 30% chromium and 2% to 20% nickel for improved surface quality, formability, corrosion and wear resistance. Heat can not harden austenitic alloys. These stainless steels are the most widely used due to their superior formability and corrosion resistance. All austenitic steels are nonmagnetic when annealed. Depending on their composition, some austenitics are magnetic when cold worked.

The combination of corrosion resistance and mechanical strength is utilized in marine hardware, pump shafting, petrochemical, pulp & paper, food processing and petroleum industries. Can also be used in “down hole” applications due to sulfide stress cracking resistance.
Field service experience have shown that NITRONIC 50 stainless has excellent resistance to sulfide stress cracking in air conditions. NITRONIC 50 in both the annealed and high-strength (hot rolled) conditions has been included in NACE Standard MR01-75/ ISO 15156-3 “Sulfide Stress Cracking Resistant Metallic Material for Oil Field Equipment,” at hardness levels up to HRc 35 maximum.
