SUS347H stainless steel pipe is a chromium-nickel steel containing 17-19% chromium and 9-13% nickel, and about 0.04-0.10% carbon. In addition, it contains approximately 0.75% niobium and is a typical example of niobium added to stainless steel.
High temperature resistance: SUS347H steel pipe can work at high temperatures, and its operating temperature range is usually between 800-1600°C. It has good oxidation resistance and is not prone to surface oxidation and corrosion in high temperature atmospheres.
Good corrosion resistance: SUS347H stainless steel pipe has excellent corrosion resistance and has good resistance to most common organic and inorganic acids. It also has good corrosion resistance to some common corrosive media in high-temperature environments, such as flue gas and slag.
Excellent welding performance: Stainless steel pipe SUS347H has good welding performance and can be easily welded using conventional welding methods. In addition, welded joints have high strength and corrosion resistance.
Enhanced performance: Through appropriate heat treatment and cold working, SUS347H alloy pipe can obtain higher strength and hardness.
