High Speed Steel –M2 with good quality and high hardness
Is M2 high-speed steel a knife? Main uses of M2 high-speed steel
Recently, enthusiasts of knives asked, how good is M2 high-speed steel for knives?
We all know that high-speed steel is also called wind steel or white steel. An alloy steel containing a large amount of carbon (C), tungsten (W), molybdenum (Mo), chromium (Cr), vanadium (V) and other elements. The high-speed steel wool material has high heat hardness after cutting, forging, annealing, semi-finished products, quenching, and toothing. When the cutting temperature is as high as 600 ° C or above, the hardness is still not significantly reduced, and the cutting speed of the saw blade can reach more than 60 meters per minute.
There are many ordinary high-speed hacksaw blades, which are not listed here one by one. Take the most commonly used in the market, and one of the most high-speed steel materials sold by our company — M2 high-speed steel.
M2 high-speed steel in China is similar to W6Mo5Cr4V2 (commonly known as 6542, US brand M2). M2 high-speed steel is mainly used for narrow and deep groove processing or cutting of metal materials such as steel, iron, copper, and aluminum. It can also be used for non-metal milling. M2 high-speed steel is one of the best mold materials for milling cutters. .
Tungsten-molybdenum-based high-speed steel M2 high-speed steel has a series of advantages such as fine and uniform carbide distribution, high wear resistance, high toughness and thermoplasticity, and high cost performance. The high-speed steel produced by it, after high-precision quenching, has a hardness of 62 ~ 64HRC, a bending strength of 4700MPa, and a 50% increase in toughness and thermoplasticity than w18Cr4V. Due to the wear resistance, heat resistance, toughness and other aspects of M2 material high-speed steel, the performance is good, and the performance-price ratio is high, which is welcomed by customers.
The main uses of M2 high-speed steel: cold forging dies, fine blanking dies, powder pressing dies, etc., shear dies, plastic dies with glass fiber, etc. Moulds suitable for shock and impact loads: deep-drawing dies, punching dies. Metal cutting saw blades, cold heading and extrusion tools.
In short, I know through some relevant tool stickers and forums that M2 high-speed steel is also used to make kitchen knives or collect knives. However, the practicality is not high. After all, its high hardness and wear resistance make it destined to be not well. Home sharpening. And its cost is generally too high, only suitable for cutter enthusiasts.
