T4003 / 3chapa de aço inoxidável cr12

What is T4003 /3Cr12 stainless steel?

3Cr12 stainless steel sheet is a ferritic stainless steel containing 12% Cr, which is equivalent to the European 1.4003 nota. It is an economical ferritic stainless steel used to replace coated carbon steel, weathering steel and aluminum. It has the characteristics of simple processing and manufacturing, and can be welded by conventional welding technology. It can be used to make: motor vehicle frames, chassis, hoppers, correias transportadoras, mesh screens, conveying troughs, coal bins, containers and tanks, chimneys, air ducts, and outer covers , Panels, sidewalks, stairs, rails, etc..

In order to improve the overall performance of the material, trace metal elements such as Nb and V can be added, and the total addition amount does not exceed 0.15%.

The company provides T4003, 1.4003, 3Cr12 stainless steel cold and hot rolled coils, steel plates, flat plates, and steel strips.
