Compared to the austenitic grades, 430 sheet and 430 SS plate has a low work hardening rate, which enables easy bending and forming and consequently this grade is less appropriate for stretch forming applications than austenitic grades.

According to the 430 stainless steel data sheet, SS 430 or 430 stainless sheet offers exceptional resistance to corrosion by sulphuric and phosphoric acids and is often the most cost effective alloy in sulphuric acid service. The additions of copper and molybdenum increase its resistance to general stress corrosion and to specific attacks such as crevice corrosion.
