I have used some M4 and like it, but Not only is M4 steel pricy, but it’s also eats a lot of belts. Our full staff of experienced engineers, estimators, detailers, and fabricators are here to get your next project PM M4 high speed tool steel is a flexible steel that provides a unique combination of high wear-resistance with high impact toughness and bend strength, which are results of the fine grain size, small carbides and superior cleanliness of the steel. Can be heat treated to 70 HRC, and the high cobalt content enables the steel to maintain high hardness at elevated service temperatures. Higher toughness at the same hardness compared to AISI M2 tool steel. It is an excellent cutlery steel. Country - United States(US) All six CPM high speed steels offer both excellent red hardness characteristics and very good wear resistance properties compared to M42. Used for high speed cutting tool, machine tool automation, for cutting high strength material. 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. New Castle, PA 16105. Refrigeration treatments may improve long term dimensional stability by transforming retained austenite. 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. 1850/2150F (1010/1175C), 30/45 minutes at temperature. Higher toughness at the same hardness compared to AISI M2 tool steel.Very popular as competition cutting steel of choice. PM M-4 can be nitrided, steam tempered or titanium-nitride coated if desired. The finer carbide structure in CPM also results in finer grain size control. b) More consistent and safer heat treat response Vacuum or atmosphere quench rate through 1850-1300F (1010-705C) range is critical to achieve optimum heat treat results. Hardened Material: Preheat to 25F (15C) below original tempering temperature (1000F (540C) minimum). M35 and M42), and super high speed (e.g. 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. M4’s incredible edge retention and overall hardness make it a steel of choice for cutting contests. Maintain above 900F (480C) during welding. Triple tempering is recommended if austenizing at 2000F (1095C). 11:25. Toll Free: (800) 932-2188 Office: (724) 657-1160 Fax: (724) 654-9550 ESSsales@elwd.com. Recently purchased the Benchmade Contego with M4 steel. Apr 21, 2019 #2. Annealed Material: Preheat 1000/1100F (540/595C), maintain over 1000F (540C) during welding. In fact, CPM M4 exhibits the best toughness properties of any high speed steel we currently produce, conventional or CPM. Common Tradenames: CPM® M4, Z M-4 PM, ASP® 2004, PM M-4, S692. Now it’s time for knife boot camp to see what M4 is made of. Apr 22, 2019 #13. Ellwood Specialty Steel. CPM Rex 76 Powder Metal High Speed Steel. Big Brown Bear 1,696 views. Very popular as competition cutting steel of choice. What is CPM M4 Steel? Refrigeration treatments should generally be performed after the first temper, and must be followed by a temper. Produced conventionally, M4 is difficult to machine in the annealed condition and grind in the hardened condition. ASTM M4 is a molybdenum intermediate type high speed steel, after quenching, surface hardness is 64 HRC min. UNS Metal Steel Grade T11304, It is a High Speed steel. M4 PM. PM M4 is a high-speed steel known primarily for its versatility, toughness and its transverse bend strength. Mainly used in custom knives, however several makers including Benchmade and Spyderco made limited runs of their knives out of Crucible CPM M4. WEAR. About AISI M4 (PM) M4 PM, a member of the molybdenum-tungsten family of high-speed steels, is a special purpose grade which utilizes its higher carbon and vanadium contents to develop excellent abrasion resistance. The High Speed Steel Comparagraph is a graphical presentation of the three properties usually considered when selecting a high speed steel for cutting tools - red hardness, wear resistance, and toughness. Made from powdered metal, M4 tool steel has a consistent microstructure that gives it outstanding resistance to wear and abrasion. Shop thousands of quality knives from all the top knife brands including Spyderco and Benchmade. M3 and M4), cobalt-type (e.g. Welding of PM M-4 is generally not recommended due to the fine-grain microstructure produced by the PM process. Note the very fine and uniformly dispersed carbide distribution in CPM steels compared to the segregated distribution and broad size range of the carbides in the conventional product. CPM 3V is an American-made steel product by Crucible Industries in Syracuse, New York. PM M4 is a molybdenum/tungsten high speed steel produced using the PM (powdered metal) steel making process. 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. If the CVD TiN treatment is used, care is required in vacuum hardening. Natlek. 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. It is well suited for premium-cutting tools of all types. PM steels have excellent grindability vs conventional steels. It is well suited for premium cutting tools of all types, particularly those used for machining abrasive alloys, castings and heat-treated materials. You’ll often see CPM-M4 used in popular custom knives and in production models from big knife brands like Spyderco and Benchmade.
