Abstract
The present invention relates to duplex ferritic austenitic stainless steel for the use chemical industry for nitric acid environments wherein good uniform corrosion resistance and high strength are required. The microstructure of the stainless steel has 35 65 volume % of ferrite preferably 45 55 volume % of ferrite the balance being austenite. The chemical composition contains less than 0 03 weight % carbon less than 1 weight % silicon less than 3 weight % manganese 26 29 5 weight % chromium 5 8 5 weight % nickel 1 3 weight % molybdenum 0 25 0 35 weight % nitrogen 1 3 weight % copper the rest being iron and inevitable impurities occurring in stainless steels.
