    摘要: The invention relates to a stainless steel exhibiting transformation-induced plasticity (TRIP) effect resistant to delayed cracking and to the method for producing the stainless steel. The resistance to delayed cracking in the stainless steel is achieved limiting the total hydrogen content of the stainless steel measured by inert gas fusion method below 4 weight ppm, preferably below 3 weight ppm by a heat treatment performed at the temperature range between 100° C. and 700° C. for 0.1-300 hours, preferably at 200-600° C. for 1-100 hours, and more preferably at 250-500° C. for 1-100 hours.

    摘要: An austenitic stainless steel including in weight % 0-0.4% C, 0-3% Si, 3-20% Mn, 10-30% Cr, 0-4.5% Ni, 0-3% Mo, 0-3% Cu, 0.05-0.5% N, 0-0.5% Nb, 0-0.5% Ti, 0-0.5% V, the balance of Fe and inevitable impurities. The content of at least one of the elements in the group of niobium (Nb), titanium (Ti) or vanadium (V) is more than 0.05% so that the total amount of niobium (Nb), titanium (Ti) and vanadium (V) contents is in the range of 0.05-0.5%. The grain size of the steel is less than 10 micrometer after annealing the cold deformed product and the difference between the yield strengths of the steel measured in transverse and parallel directions to the rolling direction is lower than 5%. Also, a method for producing the austenitic stainless steel.
