The corresponding Chinese material for CF3M is 316L stainless steel.
CF3M is a grade of austenitic stainless steel castings specified in the ASTM A351 standard of the United States. Its chemical composition is basically the same as that of 316L stainless steel (the national standard grade is ZG03Cr18Ni10Mo) in China. Both belong to low-carbon molybdenum austenitic stainless steel and have excellent corrosion resistance, especially suitable for pressure-bearing components such as chemical equipment, valves, and pipelines.
According to the Chinese standard GB/T 12230-2005 "General Valves - Technical Specifications for Stainless Steel Castings", CF3M has been directly adopted as the standard grade. The corresponding Chinese material code is ZG03Cr18Ni10Mo, which is equivalent to 316L stainless steel.
- CF3M: American standard casting grade (ASTM A351)
- 316L: American standard forged piece/rod material grade (ASTM A182 F316L)
- ZG03Cr18Ni10Mo: Chinese casting grade (GB/T 12230-2005), equivalent to 316L
Therefore, in engineering applications, the CF3M castings can directly meet the material performance requirements of 316L stainless steel.
