Certain steels require different timing, preheating and soaking temperatures, and number of tempers, e.g., M2, PM-M4, & CPM-10V. Moreover, Our Tool Steel material 100 % ultrasonic tested with good price. In applications where customers have traditionally used conventional M2 or M3 (e.g. CPM is a trademarked name for a process that is also called Powdered Metallurgy or PM steel. Thus, although wear resistance tends to increase with total alloy content and attainable hardness, there are notable peaks in the wear resistance curve at the high vanadium compositions, e.g. PM-M4 vs M2 Punches It is no longer just a question of TOUGHNESS vs. Annealed Material: Preheat 1000/1100F (540/595C), maintain over 1000F (540C) during welding. For the same reason the carbides are fine and uniformly distributed, so are any sulfides that are formed. The steel I am referring to is CPM M4, or simply M4. Cpm-m4 for sale here at Blade HQ. All six CPM high speed steels offer both excellent red hardness characteristics and very good wear resistance properties compared to M42. CPM M4 (Crucible) - Crucible's equivalent of the AISI M4 high sped tool steel. A large volume of vanadium carbides provides the high wear resistance. Refrigeration treatments may improve long term dimensional stability by transforming retained austenite. CPM M4 Tool Steel Chemical composition CPM Rex M4 can be supplied as steel plate/ sheet, round steel bar, steel tube/pipe, steel stripe, steel billet, steel ingot, steel wire rods. Both microstructures are for 2" diameter AISI T15 - CPM on right and conventionally produced on the left (500X, longitudinal cross section). Of the alloying elements generally found in high speed steels, vanadium forms the most wear resistance carbides followed in decreasing order of effectiveness by tungsten, molybdenum, and chromium. Marshalloy MQ® is a pre-hardened alloy steel plate that’s ideal for producing plastic injection molds, tool frames, holder blocks, tool and dies as well as other numerous uses. M4(AISI) - High speed tool steel. PM steels have excellent grindability vs conventional steels. Reanneal or temper 1550F (845C) 6 hours after welding. What is CPM M4 Steel?

PM-M4 *Always consult your Heat Treater* *Information Provided is General* M-4 is a super high-speed steel having a very high carbon and vanadium content for exceptional abrasion resistance. CPM 3V is an American-made steel product by Crucible Industries in Syracuse, New York. Similar European grade M2 has higher carbon so euro M2 might be offered in a PM version. Now it’s time for knife boot camp to see what M4 is made of. e) Larger size capability in full length bars Mainly used in custom knives, however several makers including Benchmade and Spyderco made limited runs of their knives out of Crucible CPM M4.. Manufacturing Technology - Ingot. Stainless Steel, Special Steel, Compressor Blading, Turbine Blading, Superalloy Supplier. M4 is a molybdenum-tungsten high speed steel that is characterized by its high abrasion, wear resistance, transverse bend strength, and impact toughness. PM M4 is a molybdenum/tungsten high speed steel produced using the PM (powdered metal) steel making process. Big Brown Bear 1,696 views. 3,987. At Crucible, we take advantage of this characteristic to re-sulfurize to high sulfur levels where enhanced machinability is required without significantly affecting the toughness properties. Toughness generally decreases with increased alloy content, particularly for the high cobalt, higher attainable hardness materials. CONVENTIONAL  HSS                         CPM. M42, upgrading can be accomplished by progressing from M42 to CPM Rex 20, CPM Rex 45, CPM Rex 54, CPM T15, CPM Rex 76 or CPM Rex 121. Common Tradenames: CPM® M4, Z M-4 PM, ASP® 2004, PM M-4, S692. Salt, oil or atmosphere quench to 1000-1100F(540-595C), equalize, then air cool to below 125F(50C) or hand warm. Free shipping on orders over $99! Characteristics. Can be heat treated to 70 HRC, and the high cobalt content enables the steel to maintain high hardness at elevated service temperatures. CPM M4 will even out wear M42 in applications where red hardness is not the controlling property. It’s a high-end or Premium tool steel high in Molybdenum and Vanadium, which give the steel a great combination of toughness and wear resistance, It’s very popular steel in the knife industry, it’s commonly used in custom knives. M4’s incredible edge retention and overall hardness make it a steel of choice for cutting contests. M4 PM. Annealed Material: Heat to 1100/1300F (595/740C), hold two hours, cool in still air. M4 is an extremely versatile high-speed steel with its extremely high carbon and vanadium contents for exceptional abrasion-resistance. 1850/2150F (1010/1175C), 30/45 minutes at temperature. PM M-4 is a high-vanadium special purpose high speed steel exhibiting better wear resistance and toughness than M2 and M3 in cold work punches, die inserts and cutting applications involving high speed and light cuts. In applications where it has been traditionally necessary to use a high cobalt material for red hardness, e.g. PM-M4 Hi Speed Steel Material Information M-4 is a super high-speed steel having a very high carbon and vanadium content for exceptional abrasion resistance. c) Significantly improved grindability M35 and M42), and super high speed (e.g. PM M-4 High Speed Steel Data Sheet. Use it for punches, dies, and high-speed cutting tools. Specifically, these potential benefits include: We have been servicing the regional area around Sioux Falls, South Dakota since 1970. WEAR. Apr 22, 2019 #13. Made from powdered metal, M4 tool steel has a consistent microstructure that gives it outstanding resistance to wear and abrasion. Maintain above 900F (480C) during welding. Thus M2 with less than 20 percent total alloy content, no cobalt, and an attainable hardness of 64-66 HRC, is at the low end of the red hardness curve; whereas CPM Rex 121 with 37 percent total alloy content, 9 percent Co, and an attainable hardness of 70+ HRC is at the top of the curve. The finer carbide structure in CPM also results in finer grain size control. Very popular as competition cutting steel of choice. Wear resistance is affected by the heat treated hardness, but more importantly it is a function of the amount and type of hard alloy carbide present in the structure of the material. I have used some M4 and like it, but Not only is M4 steel pricy, but it’s also eats a lot of belts. In fact, CPM M4 exhibits the best toughness properties of any high speed steel we currently produce, conventional or CPM. PM M48 super high speed steel is a high-performance high speed steel which exhibits superior hot (red) hardness compared to T15 and M42 high speed steels, and wear resistance comparable to that of T15. Fast Quote. One thing that has changed about this steel is the use of powder metallurgy in its manufacture. Thus, some of the higher alloy CPM-produced grades may be as tough as, or tougher than, lower alloy conventionally-produced grades. P&M Steel is a custom steel fabrication company with a limited distribution center on site. Mainly used in custom knives, however several makers including Benchmade and Spyderco made limited runs of their knives out of Crucible CPM M4. This could not be done with conventional ingot processing. M4 is a tool steel produced by Crucible Industries, a company known for the production of some of the best knife steels on the market today.
