What Are the Alloys of Stainless Steels?

Stainless steels are iron-based alloys made primarily of iron, carbon, and key alloying elements such as chromium and nickel. Known for their exceptional corrosion resistance, strength, and versatility, stainless steels play a crucial role in modern engineering and industrial applications. Whether for structural purposes or decorative finishes, stainless steels provide unmatched performance across diverse environments.

Types of Stainless Steel Alloys

There are four primary types of stainless steel, each suited for specific applications:

• Austenitic Stainless Steels: Known for their corrosion resistance and excellent weldability, making them ideal for food processing and medical applications.
• Ferritic Stainless Steels: Offer good corrosion resistance and are commonly used in automotive components and household appliances.
• Martensitic Stainless Steels: Characterised by their hardness and strength, they are commonly used in surgical instruments and cutlery.
• Duplex Stainless Steels: Combining the strengths of both austenitic and ferritic steels, duplex alloys offer superior strength and stress corrosion resistance.
