Abstract (en)
The invention relates to high chromium content, corrosion resistant, austenitic alloys having the following composition: 32-37% by weight of chromium 28-36% by weight of nickel max. 2% by weight of manganese max. 0.5% by weight of silicon max. 0.1% by weight of aluminium max. 0.03% by weight of carbon max. 0.025% by weight of phosphorus max. 0.01% by weight of sulphur max. 2% by weight of molybdenum max. 1% by weight of copper 0.3-0.7% by weight of nitrogen and usual minor constituents and impurities resulting from the production method and the remainder as iron. These alloys are suitable as materials for articles which are resistant to chemical attack.
