Type 439 is a ferritic stainless steel that outperforms Type 409 in both oxidation resistance and corrosion resistance. Type 439 is stabilized with a titanium (Ti) addition resulting in good weldability. The alloy resists intergranular corrosion and stress corrosion cracking. It has higher thermal conductivity and lower coefficient of expansion than Type 304. Type 439 performs well in oxidizing environments and resists stress corrosion cracking. The alloy’s good weldability, high thermal conductivity and low thermal expansion make it a good choice for many applications. Non-automotive applications include heat exchanger tubing, kitchen equipment, household appliances and architectural structures. Type 439 exhibit good wet corrosion resistance to chlorides, sulfates, and many organic acids and have proven to be acceptable for many automotive exhaust applications. It is also preferred where wet corrosion resistance especially to chlorides is required. . These Stainless Steel 439 Sheets and plates are used in Chemical Industries, Electrical Industries, Generator Industries, Food Industries, Shaft Industries, Cement Industries, Gas Industries, and Power Project etc.
Stainless steel 439 Sheets have good weldability, brightness, and pitting corrosion resistance. It polishes well, and is good for deep drawing. We provide various test certificates along with our products in accordance with EN 10204/3.1B, 100% radiography test report, third-party test report, raw material certificate, etc. to ensure damage free products are being delivered to our clients.
