403 stainless steelis a grade under the standard ASTM. The Chinese grade equal to 403 is 1Cr12. 403 stainless steel can be produced into 403 stainless plate, 403 stainless steel sheet, 403 stainless steel pipe, 403 stainless steel tube, 403 stainless profile steel, 403 square/rectangle hollow section.
403 stainless steel is mainly used for industrial, such as machinery, accessories, mould materials and as the turbine blade and high stress components of good corrosion and heat resistant steel.
