Introduction to 420 Martensitic Stainless Steel:
420 stainless steel is a martensitic type stainless steel, which belongs to the high carbon grade, and has good resistance to the atmosphere under hardened conditions,It has the characteristics of certain wear resistance and corrosion resistance, high hardness, etc., and is suitable for all kinds of precision machinery, bearings, electrical, equipment, instruments, meters, transportation, household appliances, as well as food tableware, stainless steel hospital equipment, etc.
Chemical composition is (%)
| C | Mn | Si | Cr | Ni | P |
| 0.16~0.25 | ≤1.00 | ≤1.00 | 12.0~14.0 | ≤0.75 | ≤0.04 |
| S | | | | | |
| ≤0.03 | | | |
420 martensitic stainless steel main areas:
1.Tool Manufacturing:
- Kitchen knives: including chef's knife, vegetable cutting knife, fish filleting knife, etc.
- Outdoor knives: such as hunting knives, camping knives, etc.
- Multi-functional tools: such as folding knives, military knives, etc.
2.medical instruments:
- Surgical instruments: including surgical blades, scissors, medical pliers, etc..
- General medical equipment: such as medical syringes, combs, etc.
3.Industrial Applications:
- Pump parts: such as pump shaft, pump impeller, etc.
- Valve parts: including valve seat ring, valve core, etc.
- Machinery parts: Components used to manufacture various industrial equipment and machinery.
4.auto industry:

Main uses of 420 martensitic stainless steel:
- Knife manufacturing: 420 stainless steel is often used to make various types of knives, including kitchen knives (such as chef knives, vegetable cutting knives), outdoor knives (such as hunting knives, camping knives), multi-functional tools (such as folding knives, military knives), etc. It has moderate hardness and good corrosion resistance, and is suitable for daily use knife manufacturing.
- Medical devices: 420 stainless steel is used in the medical industry to manufacture some common medical devices, such as surgical blades, scissors, medical pliers, etc. Its corrosion resistance and mechanical properties make it widely used in the manufacture of medical devices.
- Industrial Use: 420 stainless steel is used in the industrial field to manufacture various parts and tools, such as valves, pump parts, bearings, valve seats, etc. It is usually used in industrial applications that require high corrosion resistance and a certain mechanical strength.
- Automobile manufacturing: In the automobile industry, 420 stainless steel is often used to manufacture brake system tools, transmission system parts and some structural parts. Its corrosion resistance and mechanical properties can meet the requirements of automobile parts.
In general, 420 stainless steel is widely used in knives, medical devices, industry, and automobiles due to its moderate hardness, good corrosion resistance, and relatively economical price.
