430 Stainless Steel Sheet SS Sheet Metal 430 JIS ASTM 2B Finished
430 Stainless Steel Sheet Description:
430 stainless steel is a general steel with good corrosion resistance. Its thermal conductivity is better than austenite, its thermal expansion coefficient is smaller than austenite, its heat resistance fatigue, and the addition of stabilized element titanium has good mechanical properties at the welding seam. 430 stainless steel has the ability of oxidation resistance to corrosion, but has the tendency of intergranular corrosion.
This is the most cost effective grade of steel. So the 430 stainless steel sheet price is lower compared to other grades of stainless steels and all metallic products in general. There are different versions of the material with low carbon and high carbon content. The low carbon version, 430 stainless steel sheets are very good for welding applications as they have less carbide precipitation and less localized corrosion.

430 Stainless Steel Sheet Information:
1-1: Is this ferritic stainless steel stabilized?
No. This stainless steel grade is not stabilized which impacts weldability.
1-2: Does this stainless steel resist stress corrosion cracking?
Yes. All ferritic stainless steels including 430 show excellent resistance to stress corrosion cracking.
1-3: Is this grade easily formed?
Yes. 430 stainless steel is easily formed.
