| Product Description | ||||
|
SM22CR is a Duplex Stainless Steel material, generically called Duplex due to its dual micro structure composed of approximately 50% Ferrite and 50% Austenite. SM22CR is used in corrosive well conditions in combined presence of CO2, low H2S and Chlorides, where material strength is also required.
Launched in the early 80's, SM22CR benefits from NSSMC's unrivaled know-how in manufacturing CRA (Corrosion Resistance Alloys) materials and best-in-class quality control. SM22CR-125 is manufactured based on API 5CT/ISO 11960 and API 5CRA/ISO 13680 |
