MARTENSITIC STAINLESS STEEL HIGHLY RESISTANT TO CORROSION, AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to martensitic stainless steel highly resistant to corrosion, which contains at least one of around 0.50 wt % to around 0.60 wt % of carbon, around 0.02 wt % to around 0.08 wt % of nitrogen, around 0.1 wt % to around 0.4 wt % of silicon, around 0.3 wt % to around 0.6 wt % of manganese, around 12 wt % to around 15 wt % of molybdenum, and around 0.1 wt % to around 1.5 wt % of tungsten and iron and inevitable impurities, as well as to a method for manufacturing same. Thus, the martensitic stainless steel highly resistant to corrosion has superior manufacturability and corrosion resistance.
