3CR12 Steel Products

3CR12 Stainless Steel

3CR12 does not depend on the alloying elements nickel and molybdenum to lend their stainless properties. 3CR12 offers weldability, formability, and savings when compared to other corrosion resisting stainless steels. It also can reduce your product costs through the elimination of protective treatments and corrosion allowances. In service, utility stainless provides savings in maintenance, improved productivity, and longer service life. 3CR12 has been proven to lower life-cycle costs than other materials where corrosion or abrasion affects service conditions.

Our 3CR12 Steel Products

3CR12 is certified to ASTM A240 UNS S41003 ( It also conforms to the European grade for stainless steel type 1-4003, included in specification EN 10088, which covers stainless flat and long products.

Its fine-grained microstructure makes 3CR12 well suited for welding and other forming and fabrication. It has been successful in many applications, typically providing advantages of excellent performance and economy.
