Ultra clean stainless steel for extremely fine wire

摘要

An ultra clean stainless steel which allows wire drawing of extremely fine wire with a diameter of 30 micron or less is disclosed. This steel contains 0.006% or less of Al, 10 ppm or less of O, with an inclusion particle size of less than 10 micron.PPThis type of ultra clean stainless steel is produced by refining steel using vacuum induction furnace melting or the AOD method, and preferably carrying out electroslag refining followed by vacuum arc furnace remelting.
