摘要： A high strength steel strip excellent in shape having a duplex structure of austenite and martensite has been prepared by a process which comprises providing a cold rolled or cold rolled and annealed strip of a martensitic structure from low carbon martensitic stainless steel containing from 10 to 17 % by weight of Cr and having a carbon content of not exceeding 0.15 % by weight, causing the strip to continuously pass through a continuous heat treatment furnace where the strip is heated to temperatures within the range from (the As point of the steel + 30 DEG C.) to the Af point of the steel and not higher than 900 DEG C. so that a part of the martensitic phase may be changed to a reversed austenitic phase, and cooling the heated strip to ambient temperature, wherein the As point of the steel is a temperature of the steel of which temperature is being raised at which the transformation of martensite to austenite begins and the Af point of the steel is a temperature of the steel of which temperature is being raised at which the transformation of martensite to austenite is finished.

摘要： A heat-resistant austenitic stainless steel is disclosed. This steel essentially consists of: not more than 0.06 C, 1 - 4% Si, 0.5 - 4% Mn, not more than 0.035% P, not more than 0.005% S, 10 - 17% Ni, 14 - 20% Cr, 1 - 4% Mo, 0.01 - 0.5% A l , not more than 0.035% N, and balance essentially Fe, and may further contain small amounts of any of Cu, REM and B and the composition thereof is adjusted so that a limited amout of delta -ferrite appears in solidification. The steel has excellent hot salt corrosion resistance, weldability, salt errosion resistance of the weld and hot-workability.
