SUS317 (S31700)
Austenitic Stainless Steel SUS317
317 (S31700)Characteristics of SUS317:
SUS317 is a kind of molybdenum containing austenitic stainless steel. The content of molybdenum of SUS317 is a little higher than that of SUS316. The characteristics of SUS317 are very similar to that of SUS316. Its corrosion resistance is improved a lot due to the high content of molybdenum. In addition, it has good resistance to seawater and oxidation.Chemical composition of SUS317 (%):
