1.m2 steel is molybdenum-based high-speed steel, which has the advantages of small carbide inhomogeneity and high toughness. It is easy to overheat, so the quenching heating temperature should be strictly controlled, and the requirements for heat treatment protection are stricter. Due to its good hardness and wear resistance, it is mostly used to manufacture tools for cutting difficult-to-cut materials. M2 steel has a high tendency to carbides, so it has stricter requirements for heat treatment protection, and is suitable for molds that withstand vibration and impact loads. 2.AISI M2 Steel physical properties Factory hardness: ≤255HB Quenching temperature: 1220-1240 Hardness:≤63 3.1.3343 High Speed Steel Features Hardness (factory state): ≤255HB Curing Temperature: 1220℃-1240℃ Hardness (after heat treatment): ≤ 63 HRC It is a good choice for cutting applications due to its high wear resistance and toughness. Carbide evenly distributed and high toughness. Can be used to make milling cutters, reamers, broaches, gear cutters and other industrial tools. 4.M2 chemical composition Carbon C: 0.80 to 0.90 (allowable deviation: ±0.01) Silicon Si: 0.20 to 0.45 (allowable deviation: ±0.05) Manganese Mn: 0.15 to 0.40 (allowable deviation: +0.04) Sulfur S: ≤0.030 Phosphorus P: ≤0.030 Chromium Cr: 3.80～4.40 (allowable deviation: ±0.05) Nickel Ni: Allowable residual content ≤ 0.30 Copper Cu: allowable residual content ≤ 0.25 Vanadium V: 1.75～2.20 (allowable deviation: ±0.05) Molybdenum Mo: 4.50～5.50 (allowable deviation: size≤6,±0.05; size>6,±0.10) Tungsten W: 5.50～6.75 (allowable deviation: size≤10,±0.10; size>10,±0.20) Note: According to the agreement between supply and demand, the content of V can be 1.60～2.20 5.Our company (Dongguan Songshun Mould Steel Co., Ltd.) has been producing and exporting alloy steel plates for more than ten years.

5140 steel is medium carbon modulation steel, cold heading die steel. The steel is moderate in price, easy to process, and can obtain certain toughness, plasticity and wear resistance after proper heat treatment. Normalizing can promote tissue spheroidization and improve the cutting performance of blanks with hardness less than 160HBS. Tempered at a temperature of 550~570℃, the steel has the best comprehensive mechanical properties. The hardenability of this steel is higher than that of S45C steel, and it is suitable for surface hardening such as high frequency quenching and flame quenching. Heat Treatment AISI/SAE/ASTM 5140 Steel Heat Treatment Heat treatment specification: quenching at 850℃, oil cooling; tempering at 520℃, water cooling, oil cooling 5140 surface quenching hardness is 52-60HRC, flame quenching can reach 48-55HRC Nitriding treatment 1.7035 is a nitridable steel, and the elements it contains are conducive to nitriding. 40Cr can obtain higher surface hardness after nitriding treatment, the highest hardness of 40Cr after nitriding treatment can reach 72~78HRA, and the core hardness can reach 43~55HRC. Nitriding workpiece process route: forging – annealing – roughing – quenching and tempering – finishing – stress relief – rough grinding – nitriding – fine grinding or grinding. Since the nitrided layer is thin and brittle, a high-strength core structure is required, so quenching and tempering heat treatment should be performed first to obtain tempered sorbite to improve the mechanical properties of the core and the quality of the nitrided layer. Weldability of 5140 steel: It is easy to segregate during crystallization, and is sensitive to crystallization cracks (a kind of thermal cracks), and it is easy to crack in arc craters and concave parts of welds during welding. The carbon content is high, and it is easy to obtain a hardened structure (martensitic structure) that is sensitive to cold cracks during rapid cooling. When the cooling rate of the superheated zone is large, it is easy to form hard and brittle high-carbon martensite to embrittle the superheated zone. Welding process points 1. Generally, welding is carried out in the annealed (normalized) state. 2. The welding method is not limited. 3. Use larger line energy to appropriately increase the preheating temperature. Generally, the preheating temperature and interlayer temperature can be controlled between 250 and 300 °C. 4. The welding material should ensure that the composition of the deposited metal is basically the same as that of the base metal, such as J107-Cr. 5. Quenching and tempering heat treatment should be carried out in time after welding. If it is difficult to carry out the quenching and tempering treatment in time, intermediate annealing or holding for a period of time at a temperature higher than preheating can be carried out to eliminate diffusible hydrogen and soften the structure. For products with complex structure and many welds, an intermediate annealing can be performed after a certain number of welds have been welded. If you have any questions,pls feel free to contact us.

Introduction What is AISI 5140 Steel? AISI 5140 steel also can be called JIS Scr440 and DIN 1.7035 steel.AISI 5140 steel round bar is one of the alloy steel as well as the most popular steel grades in the productions of the machine. The AISI 5140 steel price is on the medium level and it was easy to processing. After tempering and quenching, the toughness, plasticity and wearing resistance of it will get better. Steel normalizing can make the spheroidizing for the organization of steel get easier. And it will raise the machinability of the semi-finished product with the hardness less than 160HBS. Tempering it at the temperature of 550℃-570℃ which can make it get better mechanical property. And the hardenability of it is higher than S45C steel. You can check 5140 Steel chemical composition and mechanical properties as below. use 5140 This steel is quenched and tempered and used to manufacture mechanical parts that are subjected to medium load and medium speed work, such as steering knuckles of automobiles, rear axle shafts and gears, shafts, worms, spline shafts, top sleeves, etc. on machine tools; After quenching and tempering at medium temperature, it is used to manufacture parts that are subjected to high load, impact and medium speed work, such as gears, spindles, oil pump rotors, sliders, collars, etc. Low-impact and wear-resistant parts, such as worms, spindles, shafts, collars, etc., with a solid thickness of less than 25mm on the cross-section; after quenching and tempering and high-frequency surface quenching, they are used to manufacture high surface hardness and wear resistance And parts without great impact, such as gears, sleeves, shafts, main shafts, crankshafts, mandrels, pins, connecting rods, screws, nuts, intake valves, etc. In addition, this steel is suitable for the manufacture of various transmission parts for carbonitriding, such as gears and shafts with large diameters and good low temperature toughness Test How is ASTM 5140 steel tested? AISI 5140 Steel Chemical Composition Testing-Spectrometer We are sae 5140 Alloy Structural Steel for composition testing using spectrometer.The spectrometer one-time excitation of the sample to analyze its composition method is widely accepted by the public at this stage.Compared with traditional analytical methods, the advantages of spectrometers for the detection of modern steel components are fast, accurate and efficient. This method can directly inject solid samples without chemical digestion, which can reduce the human error caused by the digestion process and the constant volume process; to good quality steel.
