Today, the Shanghai Yaluo editor will share with you the characteristics and application scope of SUS317 stainless steel bolts.
S (L) is a type of stainless steel containing molybdenum, and the molybdenum content in SUS317 stainless steel bolts is slightly higher than that in SUS317 stainless steel bolts.
Standard: JIS
Characteristics and Scope of Application:
Features: Similar to 316L, but with the addition of molybdenum metal to improve corrosion resistance. HB ≤ 195, SUS317 is used for chemical ships, chemical product reactors, and other chemical equipment that require high corrosion resistance.
