16 / 24 / 30 Gauge Cold Rolled Steel Sheet Coil Ferrite 439 / 1.4509
1.439 stainless steel
Type 439 Stainless Steel is a ferritic stainless steel designed to resist corrosion in a variety of oxidizing environments from fresh water to boiling acids. It may be used in either the annealed, cold formed or as-welded condition in many applications where other stainless steel alloys such as Type 304, Type 410, Type 409 and Type 430are used.
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.
