Is 440c Steel Good? Complete Updated Guide Of 2023

Basic 440c steel is a high-carbon stainless alloy with hardness and mechanical stress at its base. This material is perfect for components that must resist corrosion relatively well and yet not wear under repeated use.

Don’t worry if you are looking for a good component. I will explain some good terms as to whether 440c steel is good or not. Just read till the end just like you did for my previous post on the best Knife blade types in 2023 for accurate purchasing aspects.

440c Steel Composition-What Makes It Important?

  • 1.1% Carbon: Looking for a material that gives hardness, Carbon is the primary element that gives the 440c steel its hardness. It also improves wear resistance.
  • 17% Chromium: Chromium prevent steel from rust and corrosion. It also stabilizes the alloy and improves its tensile strength.
  • 0.8% Manganese: Manganese helps form martensite, the desired phase in heat treatment. In addition, it increases the steel’s tensile strength, toughness, and brittleness.
  • 0.70% Molybdenum: Molybdenum makes the steel more machinable. It also enhances the strength and toughness of the steel.
  • 0.5% Silicon: Silicon improves steel’s hardness and strength, but not as much as manganese or carbon.
  • 0.2% Phosphorus: Phosphorus increases steel’s corrosion resistance, strength, and machinability.
  • 0.02% Sulfur: A minor alloying element, sulfur works with phosphorus to improve machinability.
  • 79.5% Iron: Iron is the primary component in the alloy. It gives the steel its characteristic ductility and malleability.

Is 440c Steel Good As A Knife Material?

440c steel has a unique chemical composition that makes it a special alloy. Steel is good for knife blades for several reasons. The best knife blade material should be corrosion-resistant and have a good hardness balance. What is 440 steel, let’s check how is 440 steel works. 

The 17% chromium offers good corrosion resistance. Do you know if 440 steel is good for knife making or not, or Is 440 steel good for knife making?  The steel also has the right amount of manganese, molybdenum, and silicon to achieve the desired properties.

1. Hardness

If we talk about the 440 stainless steel hardness it’s about 58-60 on the Rockwell scale. Due to its high carbon content, it can retain a high level of steel hardness. 

Is 440 steel good for knives? It’s not as hard as other modern steel variants, but it’s the hardest in the 440 series. Also, this 440 steel is good for swords. 

2. Edge Retention

This 440 stainless steel properties have good retention and withstand high before the blade needs to be sharp. If you need a high wear resistance must try a combined effect of carbon and chromium. 

3. Wear Resistance

440c alloys have high wear resistance due to their carbon and chromium content, and do you know why is 440 stainless steel magnetic? Or What is 440 stainless steel?  440c steel blades are durable and can last for a long time.

 The best comparison of this product is 440 stainless steel vs 304. The 440c steel is ideal for chefs and other users who need knives that can withstand repeated use.

4. Corrosion Resistance

With a chromium content of 17%, the steel is highly corrosion-resistant in any environment. For knife blades, steel is ideal because it resists corrosion and rust. Corrosion-resistant knives are easy to maintain and don’t make any more rust.

5. Sharpening

Steel’s hardness makes sharpening difficult. In keeping with the 440 series, 440c steel is harder to sharpen than softer steel. As it doesn’t become too sharp like some other high-carbon steel. However, it can hold its edge for a long time.

6. Toughness

Wear and corrosion resistance reduces toughness at the expense of corrosion resistance. However, 440c steel is still tougher than other high-carbon steels, despite its lower carbon content. Due to its toughness, this steel is ideal for making knife blades.


  • Excellent hardness
  • Good retention
  • High wear resistance
  • Excellent corrosion resistance
  • Easy to maintain


  • It’s not the sharpest blade
  • Limited toughness
  • Difficult to sharp

Frequently Asked Questions:

Is 440 steel good quality?

440C steel is a great choice for many users. It is highly resistant to corrosion and wear, making it suitable for tools and knives, or other steel stuff. It is also highly durable and strong, and heat treatment can improve its wear resistance and toughness.

Is 440 stainless steel cheap?

The 440a is low-end steel, with decent edge retention and hardenability, it’s very affordable and has excellent corrosion resistance, very similar to the 420Hc and 425M, they have a very similar chemical composition, and they’re very similar in price.

Is 440 stainless steel food safe?

SAE 400 steel comes in a variety of types, and many of them meet the minimum chromium requirements to be considered food-grade. Food-safe stainless steels in this category include SAE 420 and 440C.

Final Verdict:

Is 440c steel good or not? In conclusion, this popular 440c is the best choice for making knife blades and more cutting tools. This 440c has excellent hardness, wear resistance, and corrosion resistance. Also, it is very easy to sharpen and easy to maintain. 

So, be sure to give this amazing product a quick try.
