Product Description Of 309 Stainless Steel Wire

309 stainless steel wire is a high-alloy stainless steel product, containing high levels of chromium and nickel, thus possessing excellent high-temperature resistance and corrosion resistance. This type of wire is widely used in various fields, especially in applications requiring high-temperature resistance and corrosion resistance, such as storage tanks and reactors in high-temperature equipment, pipelines, and chemical, and metallurgical industries.

Regarding chemical composition, 309 stainless steel cable mainly consists of Cr 22-24%, Ni 12-15%, and C ≤0.20%. This chemical composition configuration enables 309 stainless steel rope to exhibit good cutting performance and quality in high-energy beam processing such as laser and plasma.

Additionally, 309 stainless steel rope has good welding performance and can be welded using various methods such as argon arc welding, manual arc welding, and gas-shielded welding. The welded joints exhibit stable performance. Its hardness can also be controlled by adjusting the composition and heat treatment process to meet the requirements of different application scenarios.
