NITRONIC 40 - Austenitic Stainless Steel
High manganese and nitrogen strengthening result in a combination of high temperature oxidation resistance, excellent toughness at cryogenic temperatures and above average corrosion properties. Maximum temperature for continuous service is less than 1600 F (871 C). This alloy retains excellent toughness down to -423 F(-230 C).
