SUS 304-WPB stainless steel wire has been used generally for springs in Japan. In the case of special purposes for spring usage such as high fatigue properties or heat resistance are required, SUS 631 JI-WPC (17-7 PH) has been applied. Recentry in U.S.A (1980), new type of high strength wire which was stregthened by drawing at subzero temperature was added to the ASTM A 313 code as Type 302 Class 2.We examined mechanical properties, fatigue properties, corrosion resistance and others in comparison test with the above mentioned stainless steel wires and SUS 304 N2 steel wire. In the evaluation of heat resistance, the quality of subzero-drawing wire was intermediate between SUS 304-WPB and SUS 631 JI-WPC. In fatigue properties, subzerodrawing wire was suprior to SUS 304-WPB and typical SUS 631 JI-WPC.
