AISI 4140 Steel Characteristics 1.It is low alloy steel with chromium, molybdenum, and manganese. 2.Great toughness, fatigue strength, abrasion and impact resistance. 3.It is widely be used in the industry due to its excellent versatility and usefulness. 4.The higher carbon content in it, the higher the strength and heat treatment capabilities it is. 5.It can be oil hardened to relatively high hardenability. ASTM 4140 Steel Application 4140 steel is medium hardenability steel with good strength and good comprehensive mechanical properties after heat treatment. It has good manufacturability. The maximum temperature of use is 427 °C. It can be used to make turbine fastener, tool bodies, forming dies, brake dies and etc. And it also as the material of Oil deep well drill pipe joints and fishing tools below 2000m. 4140 Steel Round Bar Sheet Plate Heat Treatment Machinability At the annealed condition, 1.7225 alloy tool steel has good machinability. Forming DIN 1.7225 steel has high ductility. It can be formed using conventional techniques in the annealed condition. It is required more pressure or force for forming because it is tougher than plain carbon steels. Welding 1.7225 alloy steel can be welded using all advanced techniques. But, the mechanical properties of it will be affected if it is welded in the heat treated condition, and post weld heat treatment should be performed. Heat Treatment 1.7225 tool steel is heated at 845°C(1550°F) followed by quenching in oil. Before hardening, it can be normalized by heating at 913°C (1675°F) for a long period of time followed by air cooling. Forging It is forged at 926 to 1205°C(1700 to 2200°F) Hot Working 4140 steel can be hot worked at 816 to 1038°C(1500 to 1900°F) Cold Working 1.7225 steel can be cold worked using conventional methods in the annealed condition. Annealing Heat it to 800℃ – 850℃, hold until temperature is uniform throughout the section and cool in furnace. Normalizing Heat 1.7225 alloy steel to 870℃ – 900℃, hold it until the temperature is uniform throughout the section, soak for 10 – 15 minutes and cool in still air. Tempering DIN 1.7225 steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has lower tempering temperature. For example, tensile strength of 225 ksi cab be achieved by tempering at 316°C (600°F), and tensile strength of 130 ksi can be achieved by tempering at 538°C (1000°F). Hardening DIN 1.7225 alloy steel can be hardened by cold working, or heating and quenching. Test 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.

What is AISI 4140 Steel? AISI 4140 alloy steel round bar sheet plate belongs to medium hardenability steel.AISI 4140 steel has high fatigue strength and low notch sensitivity. Low- temperature impact toughness is also very high, no obvious temper brittleness. AISI 4140 steel round bar is mainly used after quenching and tempering state. it is used to manufacture high-strength parts under impact loads and the fittings with large cross-sections and other stressed members. Such as the horizontal eccentric shaft of the horizontal forging machine, the crankshaft of the forging press, and etc. Its equivalent grade is JIS SCM440 and DIN 1.7225. The properties and composition of 4140 steel round bar sheet plate as below. AVAILABLE SIZE: Round bar: Diameter(mm) Max 800mm; Length(mm) Max 12000mm. Plate: Thickness(mm) Max 800mm; Width(mm) Max 2300mm; Length(mm) Max 12000mm. 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.

Process: Roll the hot metal billet into a 6.5mm thick steel bar, that is, a wire rod, and then put it into the wire drawing device to draw wires of different diameters, and gradually reduce the diameter of the wire drawing disc for cooling, annealing, and coating. And other processing technology into a variety of different specifications of wire. It contains components: iron, cobalt, nickel, copper, carbon, zinc, and other elements.  Annealed iron wire has good elasticity and flexibility, and its softness and hardness can be controlled during the annealing process. The wire number is mainly 5#-38# (silk warp 0.17-4.5mm). Characteristics: The weaving of annealed wire barbed wire has methods such as first weaving and then plating, first plating and then weaving, etc. The treated barbed wire or steel wire mesh has excellent anti-corrosion and anti- oxidation characteristics, which can be used for construction, petroleum, chemical industry, breeding, and garden protection. , food processing and other occupations reinforcement, protection and insulation. It is softer and more flexible than ordinary black iron wire, with uniform softness and consistent color. Uses: Mainly used in construction, mining, chemical industry, welded wire mesh, welding hanger, reprocessing, etc. After annealing, the iron wire becomes soft and the flexibility increases, and the effect of making building wire and binding steel bars is more effective.

The galvanizing process is to coat the ordinary iron wire we see daily with a layer of zinc to prolong the service life of the iron wire. Iron is very easy to corrode and rust. Zinc is a metal that is not easy to rust. If zinc is plated on the surface of iron through special equipment and processes, it can resist corrosion and is not easy to rust. The stability of zinc Higher than iron, it is not easy to rust in a humid environment. Electro Galvanized Coil Wire is divided into two categories: hot-dip and cold-dip due to different production processes. Iron wire is easy to rust in air, water or soil, or even completely lost. The annual loss due to corrosion accounts for about 1/10 of the entire steel production. In order to make the surface of the fastener have a certain special function and at the same time give its surface a decorative appearance, it is generally treated by electro-galvanized wire. Application range of electro- galvanized wire. The fields involved in electro-galvanized wire are more and more extensive, and the application of fastener products has spread to machinery manufacturing, electronics, precision instruments, chemical industry, transportation, aerospace, etc. It is of great significance in the national economy.
