AISI 5140 Steel Round Bar Process Easy AISI 5140 Steel Round Bar For Sale

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. Dongguan Songshun Mould Steel Co.,LTD We are an Industrial and Trading Company with 3500,0000 hydraulic forging machine,who has about years experience in this field.We provide a great variety of steels, competitive price with good quality and keep the mass stock are over 20000 tons.Our main products are round and flat bars for alloy steel, tool steel, stainless steel, spring steel, bearing steel and etc. In those years we offer a wide range of high-quality steel for automobile manufacturing, engineering machinery, mold tooling, cutting tools manufacturing industry and also get high praise by at home and aboard clients.

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.

4140 alloy steel bar hot sale 4140 alloy steel bar price per kg

4140 steel, this steel has good workability, small processing deformation, good fatigue resistance, is a medium hardenability steel, 4140 has good strength and good comprehensive mechanical properties after heat treatment, good workability, yield High. The maximum use temperature is 427 degrees Celsius. 4140 strength, high hardenability, good toughness, small deformation during quenching, high creep strength and lasting strength at high temperature. It is used to manufacture forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods and spring clips that are heavily loaded, and can also be used for Drill pipe joints and fishing tools for oil wells below 2000m, and can be used for molds of bending machines. ASTM 4140 Surface Treatment and Heat Treatment 1.Surface Treatment Plate:Origin Black,Orign cold rolled bright, Machined,Grinded Bar:Origin Black,Orign cold rolled(drawn) bright,Turned,Peeled,Grinded Heat treatment specification Heat treatment standard: quenching at 850℃, oil cooling; tempering at 560℃, water cooling, oil cooling; 4140 Steel Applications It is used to manufacture forgings that require higher strength and larger quenched and tempered sections than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods and spring clips that are heavily loaded, and can also be used for Drill pipe joints and fishing tools for oil wells below 2000m, and can be used for molds of bending machines, etc.                     How is SAE 4140 steel tested? Our AISI 4140 steel round bar and steel plate composition detection is carried out by a spectrometer, which is fast, accurate and efficient in detection; hardness is tested by a hardness tester, The hardness tester is based on the Leeb hardness measurement principle, which can easily and quickly measure a variety of metal materials. While displaying the hardness measurement value immediately, it can be freely converted between different hardness scales, and the tolerance limit can be set in advance, and it will automatically alarm when it exceeds the range. 1. Measuring range: (170-960)HLD,(17-68.5)HRC,(19-651)HB,(80-976)HV,(3 , 0-100)HS, (59-85)HRA(13-100 )HRB 2. Measurement direction: support 360° (vertical down, oblique down, horizontal, oblique up, vertical up) 3. Hardness scale: Richter (HL), Brinell (HB), Rockwell B (HRB), Rockwell C (HRC), Rockwell A (HRA), Vickers (HV), Shore (HS) 4. Display: quarter dot matrix LCD 5. Data storage: maximum 500 groups (impact times 32 to 1) 6. Working voltage: 3V (2 AA size alkaline batteries connected in series) 7. Continuous working time: about 100 hours (when the backlight is not turned on) FAQ Q:Are you a factory or a trading company? A: The fact is that we are a company. We have own factory and several warehouses. Under the trend of globalization of the world, we established a professional foreign trade department to change the world. Q: What is your delivery date?
