IS 440C good for knife?
440c is mid-range (that used to be a high-end) stainless steel that offers great corrosion resistance and great wear resistance, and will take a great mirror polish so the answer is YES, It’s a good steel for knives, but It has low toughness.

Is 440 steel any good?
440C Steel: This steel has a carbon content range between . 95% to 1.20% and is generally considered higher-end steel. It’s prevalent in knives because it provides a good mixture of hardness and corrosion resistance and isn’t terribly expensive.
Does 440C steel rust?
The properties of 440c stainless steel 440c steel has moderate corrosion resistance when compared to other stainless steels, and it exhibits its best corrosion resistance in its hardened and tempered form. However, care must be taken to avoid over-tempering, which results in a decline in its corrosion resistance.
WHAT IS 440C steel used for?
It is a bearing steel, and used in rolling contact stainless bearings, e.g. ball bearings and roller bearings. It is also used to make knife blades. 440C can be oil quenched to achieve maximum hardness.

Is 440 stainless steel good for a pocket knife?
The answer should be evident by now, and YES, it’s suitable for knives, but not the best, it has an excellent corrosion resistance, which is great for kitchen knives and diving knives and a high hardness with a 58hrc, in the same time its cheap and affordable.
IS 440C magnetic?
As a martensitic stainless steel, 440C is magnetic and can be hardened by heat treatment. The high carbon content in 440C provides high hardness and strength. Despite this carbon content, the chromium content is sufficient to retain its stainless characteristics.
How hard is 440C stainless?
440C (UNS designation S44004) is a martensitic 400 series stainless steel, and is the highest carbon content from 400 stainless steel series. It is usually heat treated to reach hardness of 58–60 HRC.
How hard can you heat treat 440C stainless steel?
440C can be hardened for maximum hardness by oil quenching or air cooling from 1850 to 1900°F. Large sections or complex parts should be preheated to 1425°F, equalize, and then raised to the austenitizing temperature.
Is 440C a decent blade steel for hard use?
440c is mid-range (that used to be a high-end) stainless steel that offers great corrosion resistance and great wear resistance, and will take a great mirror polish so the answer is YES, It’s a good steel for knives, but It has low toughness. Therefore I wouldn’t recommend it for hard usage (A boning knife, for example), it would be a great knife for the wet environment (Fishing knife or
What is the difference between 440C and 440A?
To be clear, 440A is a solid knife steel and in fact has several advantages over 440C; it is tougher, has a higher edge stability (much), and is more corrosion resistant. But in practice it tends to be used on cheap knives and gets low end heat treatment and thus the performance is often very low.
Is 440C stainless steel good?
The polish makes the 440c stainless steel knives easy to clean and maintain. These great attributes indicate that 440C is indeed good knife steel. Since it appears in the mid-range category of steels, this knife will not cost you an arm and a leg.
What is the difference between 440A and 440C stainless steel?
The key difference between these two steel grades is that 440C contains higher carbon content and will hold an edge better than 440A. 440A, on the other hand, resists corrosion better than its sibling. As you can easily guess, sharpening 440A would be easier than 440C. The Chinese 8Cr13MoV is similar to AUS-8.
