439 stainless steel
The 439 steel grade is based on the ordinary ferrite material (430) to reduce the content of C, and the addition of stabilizing elements such as Ti, so that the steel species have improved intergranular corrosion resistance, formability and weldability. Compared with the 304 steel grade, the elongation is low (about 30%), but the strength and corrosion resistance are equivalent, and the corrosion resistance is better than the 200 series materials.
