PROCESS FOR THE FORMING OF A STAINLESS STEEL WITH A FERRITE-MARTENSITE DIPHASED STRUCTURE AND STEEL PRODUCED WITH THE SAID PROCESS

摘要

a steel composition, weight: less than 0.10% carbon and between 16% and 20% chromium - nickel between 0.2 2% manganese, and less than 2%, less than 2% of the copper and iron impurities is inherent in the mode of development, and to meet the different levels of relationship, 20% c + 1.1%? (mn + cu) = 1.5 to 2.5 is successively subjected to tempering: a rise in a temperature range from 300 to 1200.degree.(c), and at least one strain at a rate of more than 15%. this steel has a good ductility and high abrasion resistance.
