Abstract: The invention relates a duplex ferritic austenitic stainless steel having high formability utilizing the TRIP effect and high corrosion resistance with the balanced pitting resistance equivalent. The duplex stainless steel contains less than 0,04 weight % carbon, less than 0,7 weight % silicon, less than 2,5 weight % manganese, 18,5- 22,5 weight% chromium, 0,8-4,5 weight % nickel, 0,6-1,4 weight% molybdenum, less than 1 weight % copper, 0,10-0,24 weight % nitrogen, the rest being iron and inevitable impurities occurring in stainless steels.
