420 Stainless Steel
420 Stainless Steel: High-Carbon Martensitic for Edge Retention. The standard for industrial cutlery, surgical tools, and wear plates.
420 Stainless Steel
Grade 420 contains higher carbon than 410, allowing it to reach much higher hardness levels (up to 50 HRC). It is characterized by excellent polishability and high wear resistance.

Certified Quality Assurance
At Progressive Metal Manufacturing, we provide high-performance 420-grade stainless steel backed by a commitment to technical precision. Our operations are governed by a robust ISO 9001 certified quality management system, ensuring that every delivery adheres to strict material standards. We prioritize traceability and consistency, providing our clients with the documentation and reliability necessary for high-stakes engineering and manufacturing projects.
Industrial Applications & Versatility
The unique hardening capabilities of 420 stainless steel make it the premier choice for industries requiring sharp edges
and high wear resistance. It is a cornerstone material for the medical and cutlery sectors,
frequently utilized for surgical instruments, industrial knives, and professional hand tools.
Beyond tooling, its structural properties are ideal for pump shafts and plastic molds.
To maintain the integrity of your components, we recommend avoiding use in environments that
exceed the material's specific tempering temperature, as this can impact mechanical performance.
Whether you are crafting delicate medical hardware or heavy-duty industrial shafts,
Progressive Metal Manufacturing delivers the strength your project demands.
