Sheets/Plates
Type 439 is a ferritic stainless steel that surpasses Type 409 in oxidation resistance and corrosion resistance. Type 439 is stabilized with the addition of titanium (Ti), which yields good weldability. The alloy is resistant to intergranular corrosion and stress corrosion cracking. It has greater thermal conductivity and a lower coefficient of expansion compared to Type 304. Type 439 shows strong performance in oxidizing environments and resists stress corrosion cracking. The alloy's excellent weldability, high thermal conductivity, and low thermal expansion render it a suitable option for various applications. Non-automotive uses encompass heat exchanger tubing, kitchen equipment, household appliances, and architectural structures. Type 439 demonstrates reliable wet corrosion resistance to chlorides, sulfates, and numerous organic acids, proving acceptable for many automotive exhaust applications. It is also favored where wet corrosion resistance, particularly to chlorides, is essential. These Stainless Steel 439 Sheets and plates find applications in Chemical Industries, Electrical Industries, Generator Industries, Food Industries, Shaft Industries, Cement Industries, Gas Industries, and Power Projects, among others.
Stainless steel 439 Sheets exhibit excellent weldability, shine, and resistance to pitting corrosion. It has a good polishing quality and is suitable for deep drawing. We supply multiple test certificates with our products as per EN 10204/3. 1B, including a complete radiography test report, a third-party test report, a raw material certificate, etc. , to guarantee that undamaged products are supplied to our customers.
