Heat-resistant stainless steel pipe is a high-alloy stainless steel pipe belonging to the 25Cr-20Ni series. It has excellent high-temperature oxidation resistance and is suitable for heat-resistant parts below 1200°C.
Heat-resistant stainless steel pipe features
1) Excellent high temperature oxidation resistance;
2) The operating temperature range is very wide (below 1200℃);
3) Non-magnetic in solid solution state;
4) High temperature strength.
Heat-resistant stainless steel pipe application range
Exhaust pipes, pipes, heat treatment furnaces, heat exchangers, incinerators and other steel types that require heat resistance, high heat/high temperature contact parts
Heat-resistant stainless steel pipe is austenitic chromium-nickel stainless steel with good oxidation resistance and corrosion resistance. Because of the higher percentage of chromium and nickel, it has much better creep strength, can continue to operate at high temperatures, and has good high temperature resistance. Due to its high content of nickel (Ni) and chromium (Cr), it has good oxidation resistance and corrosion resistance. Acid, alkali and high temperature resistance, heat-resistant steel pipes are specially used for manufacturing electric furnace tubes and other occasions. After increasing the carbon content in austenitic stainless steel, the strength is improved due to its solid solution strengthening effect. The chemistry of austenitic stainless steel The composition characteristics are based on chromium and nickel with elements such as molybdenum, tungsten, niobium and titanium added. Since its structure is a face-centered cubic structure, it has high strength and creep strength at high temperatures.
