What are the materials of industrial thin-walled stainless steel pipes

Thin walled stainless steel pipes have good heat dissipation and corrosion resistance, so many industrial productions use this type of pipe. Although we often come into contact with stainless steel pipes, industrial pipes are very different from those we usually come into contact with. The industrial process environment is relatively harsh, so the selection of materials is also very cautious.

Austenitic 310s stainless steel has good oxidation resistance and corrosion resistance. Due to the high percentage content of chromium and nickel, it has creep resistance and can work continuously at high temperatures, demonstrating excellent high-temperature resistance. Under the same bending and torsional strength, it is lightweight and suitable for heat dissipation pipeline systems in the chemical industry. Heat resistant steel is also suitable for manufacturing various furnace components, with a working temperature of up to 1200 ℃ and a continuous usage temperature of up to 1150 ℃.

304L pipe is a variant of low-carbon 304, also known as ultra-low carbon steel, used in situations where welding is required. The lower carbon content reduces the precipitation of carbides in the heat affected zone near the weld, which may lead to intergranular corrosion (welding corrosion) of stainless steel in certain environments, such as industrial pipelines.

316 thin-walled stainless steel pipes with a carbon content less than 0.03 can be used in applications where welding cannot be annealed and high corrosion resistance is required. The comprehensive performance of this steel is superior to 310 and 304 stainless steel, and it has good high-temperature corrosion resistance when the sulfuric acid concentration is below 15% and above 85%. Typical applications include heat exchangers, dyeing equipment, film development equipment, and pulp and paper pipelines.
