Both the price of nickel and the allergic reaction that it can cause to human beings make it desirable to develop and use nickel-free austenitic stainless steels. The steels should be austenitic so as to avoid ferro-magnetism, a condition which has to be fulfilled for a number of requirements, including its use as implants in the human body, for wrist watch cases and many others. The paper presents the development of a nickel-free steel containing 11 percent manganese, 17 percent chromium, 4 percent molybdenum, and 0.9 percent nitrogen. This austenitic stainless steel has exceptional strength and corrosion resistance. These properties could result in numerous applications of the steel. A limitation, however, is that the steel is not weldable.
