DIN 17175 17Mn4 alloy steel pipes are of heat resistant pipe and used for high pressure and up to 600℃. Alloy steel with high strength and good chemical stability at high temperature. Hot-strength steel requires higher high-temperature strength and corresponding oxidation resistance. Heat-resistant steel is commonly used in the manufacture of parts that work at high temperatures in industrial sectors such as boilers, steam turbines, power machinery, industrial furnaces, and aviation, petrochemical industries. In addition to high-temperature strength and resistance to high-temperature oxidative corrosion, these components also require sufficient toughness, good workability and weldability, and certain organizational stability according to different applications. In addition, some new low-chromium nickel oxidation-resistant steel types have also been developed.
