In addition to iron and carbon, alloy steel is called alloy steel by adding other alloying elements. An iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements on the basis of ordinary carbon steel. According to the difference of added elements and appropriate processing technology, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, and non-magnetic properties can be obtained. In addition to iron, carbon and unavoidable small amounts of silicon, manganese, phosphorus and sulfur, steel also contains a certain amount of alloying elements. The alloying elements in steel include one or more of silicon, manganese, molybdenum, nickel, antimony, vanadium, titanium, niobium, boron, lead and rare earth. This steel is called alloy steel of the alloy steel system. According to their respective resource conditions, it is found in my country that the alloy steel system mainly composed of silicon, manganese, vanadium, titanium, niobium, boron, lead and rare earth accounts for more than 10% of the total steel output. 8 categories. They are: alloy structural steel, spring steel, bearing steel, alloy tool steel, high speed tool steel, stainless steel, heat resistant stainless steel and electrical silicon steel.songshunmoldsteel41404340

1.The main alloying elements of alloy steel are silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron and rare earth. Among them, vanadium, titanium, niobium, zirconium, etc. It is a strong carbide forming element in steel. Given enough carbon, they can form their own carbides under the right conditions. When carbon is lacking or under high temperature conditions, they enter into solid solution in atomic state; manganese, chromium, tungsten, and molybdenum are carbide-forming elements, part of which enters solid solution in atomic state, and the other part forms substitute alloy cementite; aluminum, copper, nickel , cobalt, silicon, etc. are elements that do not form carbides and usually exist in solid solution in an atomic state. 2.There are many types of alloy steel, usually divided into low alloy steel (content <5%), medium alloy steel (content 5% ~ 10%) and high alloy steel (content > 10%). According to quality, it is divided into high-quality alloy steel and special alloy steel; according to its characteristics and uses, it is divided into alloy structural steel, stainless steel, acid-resistant steel, wear-resistant steel, heat-resistant steel, alloy tool steel, rolling bearing steel, alloy spring steel and special properties. Steel (such as soft magnetic steel, permanent magnetic steel and non-magnetic steel). 3.Alloy steel contains more other elements than carbon steel Alloy steel refers to steel containing silicon and manganese as alloying elements or deoxidizing elements, as well as other alloying elements, and some also contain certain non-metallic elements. According to the content of alloying elements in steel, it can be divided into low alloy steel, medium alloy steel and high alloy steel. The carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the steel, and generally does not add a large amount of alloying elements, and is sometimes called ordinary carbon steel or carbon steel. Carbon steel is also called carbon steel, an iron-carbon alloy with a carbon content of less than 2% WC. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur, and phosphorus. According to the purpose, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel. According to the carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25% - 0.6%) and high carbon steel (WC>0.6%)songshunmoldsteel41404340

AISI 4340 steel is a medium carbon, low alloy steel known for its toughness and strength in relatively large sections. AISI 4340 is also one kind of nickel chromium molybdenum steels. 4340 alloy steel is generally supplied hardened and tempered in the tensile range of 930 – 1080 Mpa. Pre hardened and tempered 4340 steels can be further surface hardened by flame or induction hardening and by nitriding. The 4340 steel has good shock and impact resistance as well as wear and abrasion resistance in the hardened condition. AISI 4340 steel properties offer good ductility in the annealed condition, allowing it to be bent or formed. Fusion and resistance welding is also possible with our 4340 alloy steel. ASTM 4340 material is often utilized where other alloy steels do not have the hardenability to give the strength required. For highly stressed parts it is excellent choice. AISI 4340 alloy steel can also be machined by all customary methods.songshunmoldsteel41404340

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.

Simply put, steel is an iron-carbon alloy with a carbon content of more than 0.025% and less than 2.11%. Steel is a material of a certain shape, size and performance made of steel ingots, billets or steel through pressure processing. Most steel processing is through pressure processing, which plastically deforms the processed steel (bill, ingot, etc.). According to the different processing temperature of steel, it can be divided into cold working and hot working. The chemical composition of steel can vary greatly, and steel containing a small amount of manganese, phosphorus, silicon, sulfur and other elements, and carbon content less than 1.7% is called carbon steel ; Different alloys contain different alloying elements, such as: manganese, nickel, vanadium and so on. The application and research of steel has a long history, but until the invention of the Bainite steelmaking method in the 19th century, the production of steel was a high-cost and low-efficiency work. Today, steel is one of the most used materials in the world due to its low price and reliable performance. It is an indispensable component in the construction industry, manufacturing industry and people's daily life. It can be said that steel is the material basis of modern society.songshunmoldsteel41404340
