METHOD OF MANUFACTURING AUSTENITE STAINLESS STEEL

摘要

The present invention relates to a method for austenite stainless steel with a surface quality due to a reduction of inclusive detects, comprising: a step of producing molten steel by melting a raw material inside an electric furnace; a step of primarily refining the produced molten steel through an argon oxygen decarburization (AOD) process; and a step of secondarily refining the primarily refined molten steel through an LT process. In the step of secondarily refining the molten steel, 0.0001-0.0008 wt% of calcium with respect to the entire weight is added. The austenite stainless steel produced by the method is capable of improving the surface quality as the inclusive defects are reduced.
