3CR13 Vs. 420 420J2 Stainless Steel – What’s The Difference

If you are confused when it comes to choosing the right material for your knife, two materials that are often compared are 420 stainless steel and 3Cr13. Both are popular choices for knife making and both have advantages and disadvantages. If you need help deciding which one to choose, this blog post is for you.
In this post, we will analyze the similarities and differences between 420 stainless steel and 3Cr13 to help you make a clear choice!

‌3Cr13 equivalents include: ASTM standard: 420J2, JIS standard: SUS420J2,DIN standard: 1.4028, EN standard: X30Cr13, NF standard: Z33C13.

420 equivalents include： GB-T standard: new grade 20Cr13, old grade 2Cr13, ASTM standard: S42000, JIS standard: SUS420, DIN standard: 1.4021,EN standard: X20Cr13.

What is the difference between 420 stainless steel and 3CR13?
3cr13 stainless steel vs 420 Chemical composition
420 stainless steel contains higher levels of chromium and carbon, while 3cr13 contains higher levels of manganese and silicon.
3cr13 stainless steel vs 420 Mechanical properties
‌3Cr13‌ stainless steel has high hardness, excellent corrosion resistance and easy machining, but slightly lower toughness and corrosion resistance, and poorer welding performance. ‌420 stainless steel‌ has a higher hardness and can better resist wear, especially in high-chlorine environments. 420 stainless steel has better edge retention than 3Cr13, making it more suitable for applications that need to maintain sharpness. ‌
3cr13 stainless steel vs 420 Cost
Finally, cost is another factor to consider when choosing between these two stainless steels. 420 stainless steel is more expensive than 3cr13 because it has superior properties.

In conclusion, 420 stainless steel and 3Cr13 are popular choices for tool manufacturers. Each material has advantages and disadvantages, so it is important to think about what kind of tool you want before deciding.

is 3cr13 stainless steel good for knives?

3Cr13 is a martensitic stainless steel, also known as 420J2. It is used after quenching and tempering. Compared with 1Cr12Cr13 steel, it has higher strength, hardness and hardenability, but its corrosion resistance and thermal stability below 700℃ are lower than 1Cr12Cr13 steel. The cold processing performance and welding performance are not good, and heat treatment should be performed immediately after welding to prevent cracking.
3Cr13 is a low-carbon chromium stainless steel with high hardness, excellent corrosion resistance and easy processing. It is widely used in the manufacture of knives, molds, medical equipment, kitchen utensils, etc.
