These comparisons are approximate only. The list is intended as a comparison of functionally similar materials not as a schedule of contractual equivalents. If exact equivalents are needed original specifications must be consulted.

 
Possible Alternative Grades
Possible alternative grades to grade 304 stainless steels are given in table 5.

 

Possible alternative grades to 304 grade stainless steel
Grade Why it might be chosen instead of 304
301L A higher work hardening rate grade is required for certain roll formed or stretch formed components.
302HQ Lower work hardening rate is needed for cold forging of screws, bolts and rivets.
303 Higher machinability needed, and the lower corrosion resistance, formability and weldability are acceptable.
316 Higher resistance to pitting and crevice corrosion is required, in chloride environments
321 Better resistance to temperatures of around 600-900°C is needed…321 has higher hot strength.
3CR12 A lower cost is required, and the reduced corrosion resistance and resulting discolouration are acceptable.
430 A lower cost is required, and the reduced corrosion resistance and fabrication characteristics are acceptable.
