Abstract
There is provided a chromium-nickel austenitic stainless steel having improved resistance to intergranular stress corrosion cracking. The steel has low carbon and phosphorus content or carbon and phosphorus in solid solution fixed by niobium addition. Further resistance to transgranular stress corrosion cracking is realized with a low molybdenum content. The steel is particularly useful in applications involving exposure to high-temperature and high-pressure water and attack by chlorides.
