About Stainless Steel Strip

Stainless steel strip is an extension of ultra-thin stainless steel plate. In fact, it is also a kind of steel plate used in industry, but it is different from ordinary steel plate in that its shape is longer. The application field is also different from ordinary steel plate. At present, there are many kinds of stainless steel belts, and there are also many different production standards. He has been applied in many fields.

439 Stainless Steel

439 stainless steel reduces the content of C on the basis of ordinary ferritic material (430) and adds stabilizing elements such as Ti to improve the intergranular corrosion resistance, formability and weldability of the steel. Compared with 304 steel, although the elongation is low (about 30%), the strength and corrosion resistance are equivalent, and the corrosion resistance is better than 200 series materials. Chromium content is 12% ~ 30%. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its chloride stress corrosion resistance is better than that of stainless steel.
