Cold Rolled S43932 AISI439 DIN1.4510 Stainless Steel Metal Sheet 0.5-4mm 2D Surface

439 stainless steel is a titanium stabilized ferritic stainless steel grade with, 18 percent chromium alloy, it is designed to resist corrosion in a variety of oxidizing environments from freshwater to boiling acids, and its corrosion resistance is similar to that of 304/304L stainless steel. Type 439 may also be used in many oxidizing environments where Type 304 is considered adequate in terms of general corrosion resistance but is subject to chloride stress corrosion cracking. This variation does not require annealing after welding to restore ductility or to provide intergranular corrosion resistance. Type 439 also has superior formability capabilities and is heavily used in the automotive industry; it can be work-hardened slightly to increase tensile strength.

Excellent resistance to stress corrosion cracking, good weldability, high thermal conductivity and low thermal expansion characteristics make Type 439 stainless steel an ideal consideration for many applications, typical applications include tubular manifolds and exhaust system components.
