Which is better 440A VS 440C?
440 series has three types: 440A, 440B, and 440C. 440A is a relatively low-cost, highly corrosion-resistant stainless steel. 440C is also highly corrosion-resistant, but is capable of having a very high hardness. The hardenability of 440C is due to it having the highest carbon content in the 440 group.
Does 440A stainless steel rust?
440A Corrosion resistance Being stainless steel, it won’t easily catch rust or stains. The lower carbon content also gives it superior corrosion resistance over its siblings in the 400 steel family.
What is the best stainless steel for knives?
The Best Types of Stainless Steel for Kitchen Knives
- Cronidur 30 – Stainless Steel.
- X50CrMoV15 – Stainless Steel.
- D2 / SKD11 – Stainless Powder Steel.
- MC66 / ZDP-189 – Stainless Powder Steel.
- SG2 / SGPS – Stainless Powder Steel.

What is the difference between 440A and 440C stainless steel?
440B has a higher hardness and toughness than 440A and 440C for cutting tools, measuring tools, bearings and valves. The 440C has the highest hardness of all stainless steel and heat resistant steel for high quality cutting tools, nozzles and bearings.
Is 440 stainless good for knives?
440C is the highest Carbon steel in this series and has the highest strength, hardness, and wear-resistance than its siblings. This steel is loved by both knife makers and knife users due to its really high corrosion resistance. The steel is pretty tough, highly wear-resistant, and dependable.
Can you sharpen 440 stainless steel?
Carbon steel blades seem easy to sharpen. I once had a 440 stainless knife what would take an edge in an instant … and keep it for a while. But otherwise, for me, it’s pure guess work at whether 5, 10 or 15 minutes will produce a decent blade on any stainless knife (high dollar or cheap).
How good is 440 stainless steel?
Type 440 Stainless Steel, which comes in four different grades, 440A, 440B, 440C, 440F, offers good corrosion resistance along with abrasion resistance. All grades can be easily machined in their annealed state, they also offer resistance to mild acids, alkalis, foods, fresh water, and air.
IS 440C stainless steel good?
Grade 440C stainless steel is a high carbon martensitic stainless steel. It has high strength, moderate corrosion resistance, and good hardness and wear resistance. Grade 440C is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys.
Is the 440A stainless steel good for knives?
Is 440A stainless steel good for knives? “Good” is relative when it comes to blade steel. 440A steel is a good steel blade in that it offers excellent corrosion resistance. And as soft steel, it has high machinability (easy to work with) and is also easy to sharpen, making it good steel for knife makers.
What kind of steel is the 440 series?
440A is a 400 series Martensitic stainless steel with Carbon and Chromium content of 0.7% and 17% respectively. The high levels of Chromium give it excellent corrosion resistance, while Carbon is one of the major factors that gives the steel its characteristic hardness.
What is the hardness of a 440A blade?
With a Rockwell hardness of 55-58 HRC, 440A is a relatively soft blade steel compared to 440B or 440C. This, along with the exclusion of other carbide forming elements, makes it fairly easy to sharpen.
Which is the best steel for a knife blade?
“Good” is relative when it comes to blade steel. 440A steel is a good steel blade in that it offers excellent corrosion resistance. And as soft steel, it has high machinability (easy to work with) and is also easy to sharpen, making it good steel for knife makers.
