Stainless steel 408

Concept of stainless steel 408

Stainless steel 408 is a type of precipitation hardening stainless steel, with a matrix of austenite or martensite. This stainless steel has unique precipitation hardening (also known as aging hardening) characteristics, which can be hardened (strengthened) by a specific heat treatment process.

Chemical composition of stainless steel 408

The main chemical components of stainless steel 408 include chromium (Cr) and nickel (Ni), with contents of about 11% and 8%, respectively. In addition, stainless steel 408 may also contain other alloying elements to further improve its mechanical properties and corrosion resistance.

Mechanical properties of stainless steel 408

Stainless steel 408 has excellent mechanical properties, mainly including the following points:

High strength: After precipitation hardening treatment, stainless steel 408 has high yield strength and tensile strength, and can withstand large external forces.

Good toughness: The stainless steel shows good toughness under impact load and is not prone to brittle fracture.

Excellent heat resistance: Stainless steel 408 can still maintain good mechanical properties and stability under high temperature environment.

Application scope of stainless steel 408

Stainless steel 408 has been widely used in many fields due to its unique performance characteristics:

High temperature environment: Due to its good heat resistance, stainless steel 408 is often used for structural components and connectors in high temperature environments, such as furnaces, flues, etc.

Machinery manufacturing: In the field of machinery manufacturing, stainless steel 408 is often used to manufacture parts that need to withstand large external forces and high temperature environments, such as engine parts, transmission devices, etc.

Petrochemical: In the petrochemical industry, stainless steel 408 is used to manufacture storage tanks, pipelines and other equipment due to its excellent corrosion resistance and heat resistance.

Other fields: In addition, stainless steel 408 can also be used in construction, vehicle manufacturing and other fields as structural support and connection materials.
