AISI 420 Stainless Steel Coil – Product Overview

The AISI 420 Stainless Steel Coil is a high-carbon, martensitic stainless steel that is known for its excellent hardness, strength, and moderate corrosion resistance. Composed primarily of iron and chromium (12-14%), with a carbon content of up to 0.15%, AISI 420 provides superior wear resistance, making it an ideal choice for applications that require high strength and hardness. It is widely used in applications such as cutlery, surgical instruments, valves, and pumps where the material needs to withstand wear and corrosion, while maintaining excellent performance under high-stress conditions. Yuanchi Metal offers AISI 420 stainless steel coils that meet high-quality standards and can be customized to meet your specific needs.

Unique Features of AISI 420 Stainless Steel Coil

• High Hardness and Strength: AISI 420 stainless steel can be hardened to a high degree, providing excellent wear and abrasion resistance, making it suitable for cutting tools and industrial applications.
• Moderate Corrosion Resistance: While it provides good corrosion resistance in mild environments, AISI 420 is not as resistant to corrosion as austenitic grades like AISI 304 or 316. It is best used in applications where corrosion is not extreme.
• Magnetic Properties: AISI 420 is a martensitic stainless steel, which means it is magnetic. This can be advantageous in certain applications, including magnetic components or when magnetic properties are required.
• Good Fabricability: Although AISI 420 is hard, it can be cold worked and hardened by heat treatment, making it versatile for various manufacturing processes such as cutting, grinding, and polishing.
• Polished Finish: AISI 420 can be polished to a high gloss, making it ideal for applications where aesthetics are important, such as in cutlery or decorative components.
