347 Stainless Steel Strip (UNS S34700)
Lork Group is a reliable manufacturer and supplier of 347 Stainless Steel Strip and Coil in China. Type 347 is a stabilized austenitic stainless steel, similar to type 304, but alloyed with Niobium (Columbium) for use in applications involving continuous or intermittent service at 800-1500°F (427-816°C).
347 Stainless Steel Strip has excellent resistance to oxidation, even surpassing that of 321 in strong oxidizing conditions. The alloy maintains resistance to intergranular corrosion, while also possessing good creep strength compared to other 300 series stainless steels. The alloy is strengthened only through cold work and can be fabricated, machined, and welded via most conventional processes.
As a leading Stainless Steel strip and coil supplier in China, Lork Group manufactures and produces 347 Stainless Steel Strip of various sizes. If you have any mechanical requirements, please confirm with we. We can customize the material exactly to your requirements.
