420 stainless steel is actually a general term for a series of martensitic stainless steels. It is based on high-carbon chromium stainless steel and has hardenability, good wear resistance and corrosion resistance. It is widely used in knives, medical equipment, molds and other fields.
List of common types of 420 stainless steel
| Common Name | Specific brand | Features/Remarks |
| 420J1 | SUS420J1/X20Cr13/1.4021 | Good toughness, relatively low hardness, commonly used in scissors, knife handles, medical forceps, etc. |
| 420J2 | SUS420J2/X30Cr13/1.4028 | The hardness can reach HRC50 or above, commonly used in kitchen knives, scissors, surgical scalpels |
| 1.4034 | X46Cr13 | After heat treatment, the hardness can reach HRC55~58, suitable for cutting edge and anti-wear parts |
| 420U6 | - | It is usually used in the manufacture of knives, scissors and parts requiring high hardness and high wear resistance. |
| 1.4116 | 50Cr15MoV | After heat treatment, the hardness can reach HRC 56~58, meeting the high wear resistance requirements of kitchen knives, etc. |
6Cr13 | - | Excellent hardness and wear resistance, widely used in the razor industry |
| 7Cr13Mo | - | Excellent hardness and wear resistance, widely used in mid-to-high-end kitchen knives |
| 8Cr14MoV | - | Good corrosion resistance and wear resistance, widely used in high-end kitchen knives |
| 9Cr18MoV | - | Higher hardness, corrosion and wear resistance |
