Possible Alternative Grades

In the table below are a list of possible alternative grades to Grade 430.

Grade

Reason it may be chosen instead of 430

430F

Higher machinability than 430 is needed in bar product, and reduced corrosion resistance is acceptable.

434

Better pitting resistance is required

304

Slightly higher corrosion resistance is needed, together with greatly improved ability to be welded and cold formed

316

Much better corrosion resistance is needed, together with greatly improved ability to be welded and cold formed

3CR12

A lower corrosion resistance is acceptable in a cost-critical application
