Product Description
439 Stainless Steel U Channel：
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.

Product Advantage
A key characteristic of 439 stainless steel is its ability to resist stress corrosion cracking, making it ideal for applications such as automotive exhaust systems or outdoor equipment exposed to harsh conditions. In addition, it has good weldability and formability, allowing manufacturers to easily create complex shapes.
Another advantage of using this type of stainless steel over other higher grade alloys such as austenitic or duplex stainless steels is its cost effectiveness. This makes it an attractive option for budget-conscious projects without compromising performance.
