Product Description:
410 and 420 stainless steel round bars and rods are high-strength martensitic stainless steels known for their excellent hardness, wear resistance, and moderate corrosion resistance. These grades are particularly suitable for applications requiring a combination of mechanical strength and corrosion resistance.
410 Stainless Steel
- A general-purpose martensitic stainless steel with good corrosion resistance and high mechanical properties.
- Suitable for applications requiring moderate corrosion resistance and high strength.
420 Stainless Steel
- Known as “cutlery grade” stainless steel, 420 offers excellent hardness and higher corrosion resistance compared to 410.
- Can achieve superior hardness after heat treatment.
Key Features of 410/420 Stainless Steel Bars and Rods
- High Strength: Excellent tensile and yield strength, suitable for structural applications.
- Wear Resistance: Outstanding wear resistance, especially in 420 after heat treatment.
- Corrosion Resistance: Moderate resistance to atmospheric, water, and mild chemical environments.
- Heat Treatable: Can be hardened through heat treatment to achieve higher strength and wear resistance.
- Magnetic Properties: Both grades are magnetic, even after heat treatment.
Common Applications
- Cutlery and Tools: Knives, surgical instruments, and cutting tools.
- Automotive: Engine components, shafts, and fasteners.
- Industrial: Pumps, valves, and heat-resistant structures.
- Oil and Gas: Downhole tools, pipeline components, and drilling equipment.
- Aerospace: Components requiring high strength and wear resistance.
Available Sizes and Shapes
- Sizes: Diameters ranging from 6mm to 300mm.
- Shapes: Round bars, hexagonal bars, square bars, and custom profiles.
- Length: Standard lengths or custom cut-to-size as required.
Surface Finishes
- Hot Rolled: For industrial and structural applications.
- Cold Drawn: Provides a smooth surface with tight tolerances for precision applications.
- Polished: Aesthetic applications and enhanced corrosion resistance.
Value-Added Services
- Custom Fabrication: Cutting, machining, and finishing to exact project specifications.
- Heat Treatment: Annealing, hardening, and tempering for desired mechanical properties.
- Testing and Certification: Compliance with ASTM, ASME, and other international standards.
