<p>A stainless steel for molds having a lower delta-ferrite content is composed of alloying elements that, in percentages by mass, consist essentially of 0.01 to 0.20 carbon; 0.01 to 0.07 nitrogen; 2.0 to 4.0 manganese; 0.01 to 1.0 nickel; 11.0 to 13.0 chromium; less than 1.0 molybdenum and tungsten taken together; 0.01 to 1.5 copper; 0.01 to 1.0 vanadium; 0.01 to 0.20 sulphur; no more than 0.01 calcium, less than 0.50 aluminium; less than 1.0 silicon, the remainder consisting essentially of Fe and inevitable impurities.</p> |
