Product Description
439 Stainless Steel Strip：
The steel grade 439 reduces the content of C on the basis of ordinary ferritic material (430), and adds Ti and other stabilizing elements at the same time, so that the resistance to intergranular corrosion, formability and weldability of the steel grade are improved. Compared with 304 steel, although the elongation is low (about 30%), the strength and corrosion resistance are comparable, and the corrosion resistance is excellent 200 series materials.

Product Advantage
Has very excellent resistance to chloride stress corrosion cracking, good resistance to general corrosion, especially in fresh water and mild oxidation environment, has a long-term cost advantage, and high thermal conductivity, thermal expansion coefficient is good, can also resist continuous and periodic oxidation of 439 stainless steel linear thermal expansion coefficient is slightly lower than the equivalent carbon steel, And significantly lower than 304 stainless steel and 90-10Cu-Ni alloy (CA 706).
Product Apply
Automotive industry: Due to its excellent corrosion and heat resistance, 439 stainless steel is widely used in automotive exhaust systems. It can withstand high temperatures and harsh conditions without losing its structural integrity.
Appliances: Many household appliances, such as ovens, refrigerators, dishwashers and washing machines, require materials that are resistant to moisture and chemicals. The durability and corrosion resistance of 439 stainless steel make it ideal for these applications.
