What Is 316 Stainless Steel Pipe?

316 stainless steel pipe belongs to austenitic stainless steel. This type of stainless steel is named after its microstructure, which is mainly composed of austenite phase (face-centered cubic crystal structure).

SS 316 pipe is an austenitic stainless steel, the main components of which include iron, chromium, nickel and molybdenum. It is widely used for its excellent corrosion resistance and high temperature performance in chloride environments.

316 stainless steel pipe contains chromium, which helps to form a passivation film on the metal surface. This film protects the metal from corrosion by preventing oxygen and water from contacting the underlying metal. The addition of molybdenum also enhances the corrosion resistance of 316 stainless steel tube.

What Are The Chemical Elements And Mechanical Properties Of 316 Stainless Steel Pipe?

Chemical elements:

The addition of molybdenum gives 316 stainless steel excellent resistance to pitting and crevice corrosion, especially in chloride environments.

Mechanical properties:

These mechanical properties give 316 ss pipe excellent stability and durability in high pressure and high temperature environments.

What Are The Characteristics Of 316 Stainless Steel Pipe?

Corrosion resistance: 316 stainless steel tube has excellent corrosion resistance due to the 2-3% molybdenum element, especially in environments containing chloride ions, such as seawater, acidic and alkaline solutions in the chemical industry, etc.

Mechanical properties: It has high tensile strength and yield strength, and has good ductility and toughness.

High temperature performance: 316 stainless steel has good oxidation resistance and strength at high temperatures, can maintain stable performance, and is suitable for high temperature environments.

Machinability: 316 stainless steel pipe has good machinability and can be formed and processed by cold working, hot working, welding and other methods to meet different application requirements.
