Stainless Steel PipeStainless steel pipe/tube is a kind of hollow long circular steel, mainly widely used in petroleum, chemical, medical, food, light industry, machinery instrument and other industrial conveying pipes and mechanical structure components. In addition, the bending, torsional strength is the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also commonly used for furniture kitchenware and so on.Learn More
904L/904S13 Stainless Pipe/Tube904L stainless steel (UNS N08904, European standard 1.4539) is a super austenitic stainless steel. It is designed with ultra-high chromium, nickel, molybdenum and copper (Cr-Ni-Mo-Cu) alloy to become a top-level material resistant to strong acid and seawater corrosion. It is specially developed for chemical, marine and extreme corrosive environments.Learn More
430/SUS430 Stainless Pipe/Tube430 stainless steel is a low-cost ferritic stainless steel that provides moderate corrosion resistance and good formability, making it a popular choice for decorative, household, and industrial applications. Unlike austenitic grades (like 304), it contains no nickel, reducing cost while maintaining basic stainless properties.Learn More
- 420/SUS420J2 Stainless Pipe/Tube420 stainless steel (UNS S42000, Japanese standard SUS420) is a high-carbon martensitic stainless steel that can obtain ultra-high hardness (HRC 50-55) through heat treatment. It is a classic material for surgical instruments, knives and wear-resistant parts. Compared with 410 stainless steel, its higher carbon content (0.15-0.40%) significantly improves hardness and wear resistance, but sacrifices some toughness and corrosion resistance.

- 410/410S21 Stainless Pipe/Tube410 stainless steel (UNS S41000, Japanese standard SUS410) is the most basic martensitic stainless steel. It can obtain high hardness and strength through heat treatment and is an economical choice for wear-resistant parts such as knives and bearings. It has a simple composition (11.5-13.5% Cr), does not contain nickel (Ni), and has a certain degree of corrosion resistance and excellent mechanical properties.

- 409/SUS409L Stainless Pipe/Tube409 stainless steel (UNS S40900, Japanese standard SUS409) is an economical ferritic stainless steel. It has excellent high temperature oxidation resistance and stress corrosion cracking resistance by adding titanium (Ti) for stabilization. It is mainly used in heat-resistant scenes such as automobile exhaust systems. Its low-carbon version 409L (UNS S40930) further improves weldability and formability.

- 347/347S31 Stainless Pipe/Tube347 stainless steel (UNS S34700, European standard 1.4550) is a niobium (Nb) stabilized version of 304 stainless steel. By adding niobium (Nb ≥ 10×C%), the intergranular corrosion resistance and high temperature strength are significantly improved, making it a high-performance material for welded structures and high-temperature environments.

- 316Ti/SUS316Ti Stainless Pipe/Tube316Ti stainless steel (UNS S31635, European standard 1.4571) is a titanium (Ti) stabilized version of 316 stainless steel. By adding titanium (Ti ≥ 5 × C%), the precipitation of chromium carbide is effectively inhibited. It has both high temperature corrosion resistance and intergranular corrosion resistance, and is particularly suitable for welding thick plates and high temperature acidic environments.

- 316L/SUS316L Stainless Pipe/Tube316L stainless steel (UNS S31603, European standard 1.4404) is an ultra-low carbon version of 316 stainless steel (C≤0.03%), designed for welded structures and highly corrosive environments. By reducing the carbon content, the risk of intergranular corrosion is completely eliminated, while retaining the pitting corrosion resistance advantage brought by molybdenum (Mo), making it the preferred material for high-end fields such as chemical and medical.
Learn More
- 316/SUS316 Stainless Pipe/Tube316 stainless steel (UNS S31600, Japanese standard SUS316) is an upgraded version of 304 stainless steel. By adding 2-3% molybdenum (Mo), it significantly improves the resistance to pitting and crevice corrosion, becoming the preferred material for highly corrosive environments such as chemical and marine industries. Its austenitic structure has excellent formability, weldability and low temperature resistance.
