A4-80 Stainless Steel – Properties and Uses

Are you interested in learning more about A4 80 stainless steel, its properties, and its uses? If so, you’ve come to the right place. Read on to discover everything you need to know about this versatile alloy.

What is A4-80 Stainless Steel?

A4 80 stainless steel is an alloy composed of iron, chromium, and nickel. It is a type of austenitic stainless steel with a relatively high strength-to-weight ratio and excellent corrosion resistance. This makes it an ideal material for medical implants, tools and fasteners, food processing equipment, and architectural components. Additionally, due to its high corrosion resistance, it can be used in environments exposed to salt water or other harsh chemicals.

A4-80 Stainless Steel Properties

A4 80 stainless steel has a wide range of properties that make it valuable for many different applications. The most notable of these properties include:

  • Its excellent corrosion resistance (up to 600°F).
  • Superior tensile strength (up to 800 MPa).
  • High malleability (up to 650°F).
  • Excellent formability (up to 250°F).
  • Good weldability and ductility.

Additionally, this material has good fatigue strength (up to 400 MPa), making it suitable for cyclic applications such as valves or pumps. Finally, it has low thermal expansion coefficients making it useful in precision machining processes like CNC milling or turning.

  • A4 80 is martensitic stainless steel with high chromium content.
  • A4 80 has excellent corrosion resistance, especially in marine environments.
  • A4 80 has good mechanical properties and can be heat treated to achieve a wide range of mechanical properties.
  • A4 80 is easy to weld and can be welded using all standard welding methods.
  • A4 80 is non-magnetic and can be used in applications where magnetic materials are not desired.

A4-80 Stainless Steel Uses
