Heat Treatment
The heat treatment process for grade 420 stainless steel involves annealing at a temperature range of 840 to 900°C, followed by slow furnace cooling at 600°C, and finally air-cooling. Another heat treatment option is the process annealing method, which involves annealing at a temperature range of 735 to 785°C, followed by air-cooling. Both methods aim to enhance the material’s properties, and their meanings should not be altered.

420 Stainless Steel vs 304
420 stainless steel vs 304 stainless steel are both popular grades of stainless steel, but they have some important differences in their composition, properties, and applications.
| Feature | 420 SS | 304 SS | 420HC SS |
|---|---|---|---|
| Hardness | High | Medium | Very High |
| Corrosion Resistance | Moderate | Excellent | Moderate |
| Weldability | Limited | Good | Limited |
| Common Applications | Tools, molds, wear parts | Food, chemical equipment | High-end knives, cutting tools |
Composition:
420 stainless steel contains a higher percentage of carbon (between 0.15% and 0.40%) than 304 stainless steel (0.08% max).
304 stainless steel contains a higher percentage of chromium (between 18% and 20%) than 420 stainless steel (between 12% and 14%).
Properties:
420 stainless steel has a higher hardness and strength than 304 stainless steel, but it is less corrosion-resistant.
304 stainless steel has excellent corrosion resistance, especially in acidic and corrosive environments, but it is not as hard or strong as 420 stainless steel.
420 stainless steel has good wear resistance and can maintain its properties at high temperatures, while 304 stainless steel is more suitable for lower-temperature applications.
Applications:
420 stainless steel is commonly used in the manufacturing of cutting tools, surgical instruments, and molds, where high hardness and wear resistance are required.
304 stainless steel is widely used in various applications such as food processing equipment, chemical processing equipment, and architectural applications, where corrosion resistance is critical.
In summary, both 420 and 304 stainless steel have their own unique properties and applications. The choice between the two will depend on the specific requirements of the application.
FAQ
Does 420 stainless steel rust?
Yes — While it has moderate corrosion resistance, prolonged exposure to high humidity, salt, or acidic environments may cause surface rust. Protective coatings or maintenance are recommended.
Can 420 SS be welded?
Yes, but use welding materials compatible with martensitic stainless steel. Post-weld heat treatment is recommended to reduce stress.
What is the difference between 420 and 420HC?
420HC has higher carbon content and achieves higher hardness after heat treatment, making it ideal for cutting tools.
Can Huaxiao Metal provide custom sizes and finishes?
Yes, we can provide fully customized 420 SS sheets to meet your industrial requirements.
