The high mechanical properties of 431(16Cr-2Ni) Cr steel can be obtained by heat treatment. The corrosion resistance of 431(16Cr-2Ni) Cr steel is better than 410 and 430 steel. 431 stainless steel corresponding to China 1Cr17Ni2, Japan JIS SUS431.
This is the most cost effective grade of steel. So the 431 Stainless Steel tube 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, 431 tubes are very good for welding applications as they have less carbide precipitation and less localized corrosion.
