1. Chemical composition and manufacturing process
TP347H stainless steel pipe is mainly composed of alloy elements such as Cr Ni Mo Ti, among which the C content is less than 0.08%, titanium+niobium ≥ 0.70%, and other elements. This material adopts the production process of seamless steel pipes and welded steel pipes.
2. Physical performance
TP347H stainless steel pipe has excellent physical properties, especially high temperature resistance and oxidation resistance. Its tensile strength is 515MPa, yield strength is 205MPa, hardness is 81HRB, tensile strength is 74.8Ksi (515MPa), elongation is 35%, and the microstructure is austenite.
3. Chemical properties and corrosion resistance
TP347H stainless steel pipe has excellent corrosion resistance, which can withstand the corrosion of water vapor, air, food, and chemical substances, including acids, and chloride ions. At the same time, it also has high-temperature strength, which can maintain the chemical stability and physical properties of the material in high-temperature environments.
