Possible Alternative Grades
Table 5. Possible alternative grades to 904L stainless steel.
Grade | Why it might be chosen instead of 904L |
316L | A lower cost alternative, but with much lower corrosion resistance. |
6Mo | A higher resistance to pitting and crevice corrosion resistance is needed. |
2205 | A very similar corrosion resistance, with the 2205 having higher mechanical strength, and at a lower cost to 904L. (2205 not suitable for temperatures above 300°C.) |
Super duplex | Higher corrosion resistance is needed, together with a higher strength than 904L. |
