First, the material characteristics of TP347HFG stainless steel seamless pipe
TP347HFG stainless steel seamless pipe is a high-alloy heat-resistant steel with excellent high-temperature oxidation resistance and good corrosion resistance. Its chemical composition mainly includes chromium, nickel, and a small amount of niobium and other elements, which together give TP347HFG stainless steel excellent comprehensive properties. TP347HFG stainless steel has a high chromium content, which enables it to form a dense oxide film under high-temperature conditions, effectively preventing further erosion by oxygen. At the same time, the addition of nickel further improves the corrosion resistance of the material, enabling it to maintain stable performance in a variety of corrosive media.
Second, the manufacturing process of TP347HFG stainless steel seamless pipe
The manufacturing process of TP347HFG stainless steel seamless pipe mainly includes raw material preparation, smelting, and casting, hot rolling and piercing, cold drawing or cold rolling, heat treatment, and inspection.
In the raw material preparation stage, high-quality alloy raw materials need to be selected and mixed according to a certain ratio. During the smelting and casting process, the raw materials are melted into liquid through high-temperature smelting and then cast into billets. Hot rolling piercing is to heat the billet to a certain temperature and then pierce it through a hot rolling mill to form the initial shape of the seamless steel pipe.
Cold drawing or cold rolling is to further process the steel pipe after hot rolling piercing to achieve the required size and accuracy. The heat treatment process includes steps such as solution treatment and stabilization treatment to eliminate the residual stress inside the steel pipe and improve the mechanical properties and corrosion resistance of the material.
Finally, after strict inspection and testing, ensure that the quality of TP347HFG seamless steel pipe meets the relevant standards and requirements. These inspections include chemical composition analysis, mechanical properties testing, metallographic structure inspection, and corrosion resistance testing.
