420 Stainless Steel Bar Supplier | Manufacturer | Exporter
Introducing Shanghai Huaxiao Metal – Your Trusted 420 Stainless Steel Bar Supplier, Manufacturer, and Exporter!
420 Stainless Steel Bar, like most other easily machinable stainless steel bars, has its machinability improved by the addition of sulfur, which forms manganese sulfide inclusions; the addition of sulfur also reduces corrosion resistance, weldability, and formability to levels lower than its non-machinable equivalent, Grade 410.
In today’s industrial world, finding a reliable stainless steel supplier is crucial. Welcome to Huaxiao, we have been engaged in the stainless steel industry for more than ten years. We bring you the best quality 420 stainless steel bar supply services.

Corrosion Resistance:
420 stainless steel bars have good corrosion resistance in the passivated state, especially in dry atmospheric environments and fresh water. However, when exposed to humid and corrosive media, 420 has low corrosion resistance, so it is not suitable for use in harsh environments. Hardened 420 stainless steel shows better corrosion resistance.
Heat Resistance:
420 stainless steel shows moderate oxidation resistance at high temperatures, but due to its martensitic structure, it becomes brittle in environments above 650°C, so it is not suitable for use at continuously high temperatures. It is generally recommended that 420 stainless steel bars be used at operating temperatures below 400°C.
Manufacturability:
420 stainless steel has good manufacturability and is often used in the manufacture of knives, valves, shafts, etc. High hardness and mechanical strength can be obtained through proper heat treatment.
Cold Workability:
420 stainless steel has poor cold workability, especially after heat treatment. It may have problems with cracking and brittle cracking during cold working, so large deformation operations during cold working are not recommended.
Hot Workability:
420 stainless steel has good hot workability, but the heating temperature should be controlled between 980°C and 1180°C. It can be formed by forging and hot rolling, but excessive cooling should be avoided during cooling to prevent material embrittlement.
Machinability:
420 stainless steel has moderate machinability. It is relatively easy to process in the annealed state, but the machinability will decrease after hardening treatment. Slow-cutting and wear-resistant tools are generally used to improve the processing effect.
Heat Treatability:
420 stainless steel can be improved by quenching and tempering heat treatment to improve its hardness and mechanical strength. The quenching temperature is usually between 980°C and 1035°C, followed by oil or air cooling. The hardness and toughness of quenched 420 stainless steel can be adjusted by tempering.
Weldability:
420 stainless steel has poor weldability and is prone to cracking. In order to improve the welding quality, preheating is usually required, and heat treatment is performed after welding to reduce welding stress and brittleness.
Applications of 420 Stainless Steel Bar:
- Cutlery: 420 stainless steel is often used to make knives, scissors, and other cutting tools due to its corrosion resistance and hardness.
- Surgical Instruments: Its high strength, hardness, and corrosion resistance make it suitable for surgical instruments and dental tools.
- Industrial Tools: 420 stainless steel bars are used in various industrial applications such as shafts, pump parts, valve components, and tooling fixtures.
- Bearings and Bushings: Its corrosion resistance and moderate strength make it suitable for use in various machinery, such as bearings and bushings.
- Textile Industry: In the textile industry, 420 stainless steel bars are utilized for components like needles and pins due to their hardness and wear resistance.
- Aerospace Components: Some aerospace components, particularly those requiring moderate corrosion resistance and good strength, utilize 420 stainless steel bars.
- Food Processing Equipment: Due to its corrosion resistance and ease of cleaning, 420 stainless steel is often used in food processing equipment such as cutlery, trays, and blades.
- Firearms: Due to its hardness and corrosion resistance, it’s used in some firearm components, such as pistol slides and barrels.
- Chemical Processing Equipment: 420 stainless steel bars find applications in various chemical processing equipment due to their resistance to certain chemicals and moderate strength.
- Decorative Applications: Its aesthetic appeal, along with its corrosion resistance, makes it suitable for decorative applications such as architectural trim and jewelry.
