CF8, CF8M, CF3, CF3M are stainless steel castings in the American Standard ASTM A351 standard. CF8M is equivalent to China's ZG0Cr17Ni12Mo2. Corresponds to 316 stainless steel. CF8 is equivalent to China's ZG0Cr18Ni9. Corresponds to 304 stainless steel. CF3 is equivalent to 304L. CF3M is equivalent to 316L.

Differences between CF8M and 304. One major difference between these two stainless steel alloys is their level of corrosion resistance; At the same time, both offer excellent protection from rusting, or corrosion on their own, cf8m offers superior corrosion resistance compared to 304 thanks to its higher molybdenum content.

Both CF8M and CF3M stainless steels have good mechanical properties. They are both strong and ductile, and can be easily formed and welded. However, CF8M stainless steel is slightly tougher than CF3M stainless steel due to its higher chromium and molybdenum content. Applications. CF8M and CF3M stainless steels are used in various …
