CPM M4 steel hardness. Stainless steel is a popular class of material for knife blades because it resists corrosion and is easy to maintain. Advantages: Relative toughness, wear resistance. Steel is a product of iron and carbon. As indicated in this datasheet from its Crucible. M4 will not rust as easily as 1095 but it will rust I'd you don't clean it. CPM M4 steel HRC is 63.5 to 65.5 RC. It can be hardened to around 62-64 HRC but note M4 is a carbon steel is not considered stainless with relatively low levels of chromium. 154CM / ATS-34 steels Technically referred to as CPM Rex M4 HC, the CPM M4 steel is a special-purpose high-speed steel that is created by the Crucible Industries using the powder metallurgy process. The CPM-M4 is a very high-performance carbon-steel. The high hardness comes from the high carbon content used in making this alloy. What is CPM M4 Steel? It’s noted for its high vanadium content and its unique composition that promise great wear resistance, high transverse bend strength, and exceptional high-impact toughness. CPM M4 provides superbly balances levels of abrasion resistance and toughness through high doses of molybdenum (hence the “M”), vanadium and tungsten together with reasonably high levels of carbon. M4 model Eye Bolt rod total length 53.5mm, thread length 32mm, ring inner diameter 9mm(Product measurement in millimeters, 1 mm = 0.0393701 inches) 304 stainless steel, high hardness, corrosion resistance, can be used in humid environments, and do not worry about rust It will resist deformation and chipping more so then many other steels used in … M4 is a great steel and it's tough to beat with cerakote applied. To understand what makes chrome steel rust, it is first important to have a plain understanding of the science that typically prevents it from rusting. However, it is not impervious to corrosion or rust. With such a high hardness, CPM M4 steel knives usually deliver high resistance to surface deformation, penetration, deformation, and even scratching. CPM M4 Steel - This steel has excellent wear resistance and toughness. Popular M4 Knives: Spyderco Paramilitary 2 (Sold Out) Spyderco Military; D2 Steel - This steel has high chromium content, just less than what might classify it as stainless steel. Oiling the steel ensures water runs off of it and does not penetrate the pores in the steel, creating rust. Crucible doesn’t only forge stainless steels, but also carbon steel as well. Some knife steels, like VG-10, have carbon and steel mixtures but they also use chromium for corrosion resistance, so these would need far less and perhaps even no oil for longevity. CPM M4. Cerakote works wonders. Has about 1.42% carbon. Disadvantages: Relatively more difficult to sharpen than CPM 3V and predecessor tool steels like A2, not as tough as CPM 3V or CPM 4V. Because of this it has good rust resistance. What it is: CPM M4 is a "Crucible Particle Metallurgy" carbon tool steel, widely regarded as a "super steel" for its properties and performance. Combined with its excellent wear resistant properties and good grindability (comparable to conventional M2) CPM M4 represents the best high performance “general purpose” high speed steel on the market today. In fact, CPM M4 exhibits the best toughness properties of any high speed steel we currently produce, conventional or CPM. My BM 810 was in my pocket every day for 6 months and never rusted. In order for a steel to be considered stainless it must have a chromium content of at least 10.5%. CPM M4 has good edge holding, sharpening ease, toughness, strength, and is not a rust monster people make it seem like. Stainless steel contains iron, carbon, and anywhere from 12-30% chromium. It gets super sharp, very easily. This comes at the cost of losing some of its corrosion resistance.
