What is CPM 440v?
(AISI 440C Modified) CPM S60V is a unique tool steel made by the Crucible Particle Metallurgy process. It is designed from a 440C stainless base analysis with added high carbon and vanadium for exceptionally good wear resistance.
What does CPM stand for knives?
CPM stands for Crucible Particle Metallurgy and is a method of producing higher alloyed grades of superior quality than could be accomplished through conventional steelmaking. CPM steel is useful for high-alloy tool steel and high speed steel.
Is CPM S30V a good knife steel?
CPM S30V is considered a premium grade knife steel. It is so expensive that it strongly affects the price of the knife, and is largely used in higher-end production and custom knives. Buck Knives calls it “the absolute best blade steel available”.
What is CPM S30V stainless steel?
CPM® S30V® is a martensitic stainless steel designed to offer the best combination of toughness, wear resistance and corrosion resistance. Its chemistry has been specially balanced to promote the formation of vanadium carbides which are harder and more effective than chromium carbides in providing wear resistance.
What is S90V steel?
CPM S90V® is a unique tool steel made by the Crucible Metallurgy process. It is a martensitic stainless steel with a high volume of vanadium carbides for exceptionally good wear resistance. S90V offers substantial improvements in wear resistance over 440C and D2, and other high chromium tool steels.
How tough is CPM 3V?
Hardness. The CPM 3V steel has a Rockwell hardness rating of 58-60HRC, which is considered a relatively decent score for a steel blade. The CPM 3V steel is used in applications where chronic breakage, chipping, and wear are encountered on a regular basis with other tools.
Is CPM S30V the same as S30V?
To note, Crucible Particulate Metallurgy S30V (CPM S30V) and S30V are the same steel. In recent years, there have been advances to make the best combination of hardest, wear resistance, and corrosion resistance steel and S30V powder steel is a product of that effort.
Is S30V or S90V better?
When it comes to edge retention, S90v steel is far better than S30v steel as it can stay sharp for an incredible amount of time. However, S30v steel is much easier to sharpen, and some people find it to be a more practical option for a knife you intend to sharpen yourself.
Is 440 steel Good for knives?
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.
