TP304H stainless steel seamless steel pipe characteristics
TP304H belongs to the austenitic stainless steel series, which is the high temperature version of 304 stainless steel, with excellent high temperature resistance and good corrosion resistance. Its main chemical composition includes chromium (chromium Cr: 18~ 20%, nickel Ni: 8.0~ 10.5%, Manganese Mn: ≤ 2%, silicon Si≤ 1%, phosphorus P: ≤ 0.045%, sulfur S: ≤ 0.03%, carbon C≤0.040~0.10. Such elements. These components give the TP304H seamless pipe the following remarkable characteristics:
- ** High temperature stability ** : TP304H can maintain structural stability at higher temperatures and can usually work in the range of 550°C to 870°C for a long time without significant tissue changes or performance degradation, which makes it ideal for high temperature environments.
- Excellent corrosion resistance ** : Due to the sufficient chromium and nickel elements, TP304H has good corrosion resistance to most oxidizing media, weak acids, weak bases and organic compounds, and can maintain long-term stability in a variety of harsh environments.
- ** Good mechanical properties ** : At room temperature, TP304H shows good strength, toughness and ductility, and can withstand a certain impact load to ensure reliability in various application scenarios.
- ** Easy processing and welding ** : The material has good processability and weldability, and can be made into various shapes and sizes through a variety of forming processes such as cold drawing, hot rolling, etc., while the strength of the welded joint is close to the base material, which is convenient for on-site construction.
