310S, 314 products need to resist high temperature
316, 316L products need to resist acid corroison
 
 
  Major Types of Stainless Stell:
According to chemical composition, stainless steel can be divided into two major types:
1.  The chromium-nickel grade, with the AISI/ASTM specification is usually identified as "3" series: 302, 302HQ, 303, 304H, 304L, 305, 308, 310S, 314, 316, and etc.
2.  The chromium grade is identified as "4" series: 410, 420, 430 in AISI/ASTM.
