Application Cutting Tools, Precision Parts

Hemaokang Steel (Shandong) Co., Ltd. is proud to offer our high-quality 420 Stainless Steel Rod with an 8mm diameter and 500mm length, precision-hardened to HRC 48-52 for demanding cutting tool applications. As a reliable supplier with an annual export value of US$50 million to US$100 million and a global customer base, we ensure that every rod meets rigorous quality standards. This product combines excellent corrosion resistance, wear resistance, and dimensional stability, making it an ideal choice for manufacturers requiring consistent performance in cutting, machining, and tooling operations.

Key Features & Technical Specifications

Material Grade: 420 stainless steel – a martensitic grade known for its good hardness and moderate corrosion resistance.
Diameter: 8mm (tolerance: +/-0.05mm) – suitable for precision cutting tools, shafts, and pins.
Length: 500mm (custom lengths available upon request).
Hardness: Fully hardened to HRC 48-52, providing excellent edge retention and wear resistance for cutting applications.
Surface Finish: Bright, smooth finish with minimal surface defects, ensuring consistent performance.
Heat Treatment: Controlled hardening and tempering process to achieve uniform hardness and reduce internal stress.
Straightness: Within 0.5mm per meter – critical for rotating or sliding applications.

Advantages for Cutting Tool Applications

Excellent Edge Retention: The hardened HRC 48-52 ensures that cutting edges stay sharp longer, reducing tool change frequency.
Corrosion Resistance: 420 stainless steel offers good resistance to mild corrosive environments, extending tool life in humid or coolant conditions.
Machinability: Despite its hardness, the rod can be machined, ground, and polished with standard equipment, enabling custom tool geometries.
Dimensional Accuracy: Tight tolerances on diameter and length minimize post-processing, saving time and material cost.
Versatility: Suitable for knives, scissors, surgical instruments, woodworking tools, and industrial blades.

Frequently Asked Questions (FAQ)

Q: What is the main application of this 420 stainless steel rod?
A: It is primarily used for manufacturing cutting tools such as knives, blades, surgical instruments, and industrial cutting edges, where hardness and moderate corrosion resistance are required.
Q: Can you supply rods with different diameters or lengths?
A: Yes, we offer custom sizes. Please contact us with your specific requirements; we can produce rods with diameters from 3mm to 50mm and lengths up to 6000mm.
Q: Is the hardness uniform across the entire rod?
A: Yes, our heat treatment process ensures consistent hardness throughout the cross-section and length, meeting the HRC 48-52 specification.
Q: What surface finish is available?
A: Standard finish is bright/polished. We also offer a ground finish for higher precision applications. Please specify when ordering.
Q: Do you provide material test certificates?
A: Yes, we can provide a mill test certificate (MTC) for each batch, including chemical composition and mechanical properties, upon request.
Q: How is the rod packaged for export?
A: Rods are bundled with steel straps, wrapped in protective paper or plastic, and packed in wooden crates or pallets to prevent damage during transit.
Q: What is the lead time for this product?
A: For standard sizes (8mm×500mm), lead time is typically 7–15 days after order confirmation. Custom sizes may require 15–25 days.
Q: Is this material suitable for high-temperature applications?
A: 420 stainless steel is not recommended for temperatures above 400°C (750°F) due to loss of hardness. For high-temperature cutting tools, consider alternative grades like HSS.
