Jiangsu Jend Tube Co., Ltd. As a manufacturing enterprise integrating R&D, production and sales, its product types and application fields can better reflect the development trends and technical requirements of the current stainless steel tube industry.

Basic classification and performance characteristics of stainless steel tubes

Stainless steel tubes are mainly divided into three categories according to metallographic structure: austenite, ferrite and martensite. In addition, there are special alloy steels such as duplex stainless steel and nickel-based alloys.

Austenitic stainless steel tubes (such as TP304, TP316, TP321, etc.) have good oxidation resistance and corrosion resistance, and are suitable for most neutral and weakly corrosive environments. This type of steel tube is widely used in the chemical, pharmaceutical, food, pressure vessel and other industries.

Ferritic stainless steel tubes (such as TP430, TP405, etc.) are stable in terms of stress corrosion cracking resistance and have high thermal conductivity. They are usually used in heat exchange systems and automobile exhaust devices.

Martensitic stainless steel tubes (such as TP410, 1Cr13, etc.) have certain strength and hardness and can be used in occasions with high mechanical properties, such as valves, pump shafts, etc.

Duplex stainless steel tubes (such as S31803, S2205, etc.) combine the characteristics of austenite and ferrite, have both strength and corrosion resistance, and are suitable for marine engineering and oil and gas transportation systems.

Nickel-based alloys and special alloy tubes (such as Inconel 625, Monel 400, etc.) are suitable for high temperature, high pressure or strong corrosion environments, and are mainly used in high-demand fields such as energy, aerospace and deep-sea operations.
