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. |
