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.

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.

Condition: Cold rolled(drawn)≤50mm, Hot rolled≤12-250mm, Hot forged≥50mm.   AISI 4140/DIN 1.7225 Introduction: AISI 4140 alloy steel is chromium, molybdenum, manganese containing low alloy steel. It has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength.   Fabrication and Heat Treatment: 1. Forging Preheat the steel carefully, then raise the temperature to 1150-1200°C for forging. Do not forge below 850°C. 2. Annealing Heat the AISI 4140 slowly to 800-850°C and allow enough time for the steel to be thoroughly heated. Cool slowly in the furnace to 480°C followed by air cooling. 3. Stress Relieving When parts are heavily machined, ground or otherwise subject to cold work, stress relieving will be beneficial prior to hardening. 4. Hardening AISI 4140 steel is usually supplied ready heat treated to 18-22HRC. If further heat treatment is required annealed AISI 4140 should be heated slowly to 840- 875°C and after adequate soaking at this temperature quench in oil. Temper as soon as the tools reach room temperature. 5. Tempering Heat the AISI 4140 carefully to a suitable temperature selected by reference to a tempering chart or table (usually between 550-700°C, soak at the temperature for 2 hours per 25mm of ruling section, then allow to cool in air. Tempering between 250-375°C is not advised as tempering within this range will seriously reduce the impact value. 6.

316L 6mm Stainless Steel Plates 1D Heat Annealed AMS 5507 Type 316 Austenitic Stainless Steel Sheets Metal AMS 5507 Flat rolled No.1 or 2B overview ASTM A240 Type 316 is the second-most common stainless steel next to 304. Stainless Steel Sheet Type 316 generally contains 16% chromium and 10% nickel, with the addition of molybdenum normally ranging from 2-3%. Molybdenum increases corrosion resistance, particularly against chlorides and other industrial solvents. While there may be a difference between the chemical compositions of SA 240 type 316L Perforated Sheet and 304, their mechanical properties are similar. ASTM A240 Grade 316 Chequered Plate is commonly used in many industrial applications involving processing chemicals, as well as high-saline environments such as coastal regions and outdoor areas where de-icing salts are common. Due to its non-reactive qualities, 316 Stainless Steel Strip & Mesh Sheet is also used in the manufacture of medical surgical instruments. 316 Stainless Steel is more corrosion resistant than grade 304 and is suitable for marine and coastal applications.
