| Application areas | The combination of corrosion resistance and mechanical strength is utilized in marine hardware, pump shafting, petrochemical, pulp & Equipment for the Paper Industry, Paper Industry, food processing and petroleum industries. Can also be used in “down hole” applications due to sulfide stress cracking resistance. 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. | |
| Corrosion properties | Field service experience have shown that NITRONIC® 50 stainless has excellent resistance to sulfide stress cracking in air conditions. | |
| Heat Treatment | Annealed, for most applications, the 1066°C condition should be selected, as it provides a higher level of mechanical properties along with excellent corrosion resistance. A high strength version can also be supplied with min. yield at 585MPa. | |
