In 42CrMoS4, vanadium, titanium, niobium, zirconium, etc. are strong carbide- forming elements in steel. As long as there is enough carbon, under appropriate conditions, respective carbides can be formed. The atomic state enters the solid solution; manganese, chromium, tungsten, and molybdenum are carbide- forming elements, part of which enters the solid solution in the atomic state, and the other part forms a replacement alloy cementite; aluminum, copper, nickel, cobalt, and silicon are not Elements that form carbides generally exist in solid solution in the atomic state. The main solid-state phase transformation of 42CrMoS4 steel when heated is the transformation from non-austenite phase to austenite phase, that is, the process of austenitization. The whole process is related to the diffusion of carbon. Among the alloying elements, non-carbide-forming elements reduce the activation energy of carbon in austenite and increase the speed of austenitization; while strong carbide-forming elements strongly hinder the diffusion of carbon in steel and significantly slow down the process of austenitization. process. The phase transformation of 42CrMoS4 steel during cooling refers to the decomposition of supercooled austenite, including pearlite transformation (eutectoid decomposition), bainite transformation and martensite transformation. Taking the effect of alloying elements on the isothermal transformation curve of supercooled austenite as an example, most alloying elements, except cobalt and aluminum, all play a role in slowing down the isothermal decomposition of austenite, but the effects of various elements are different. different. Non-carbide-forming elements (such as silicon, phosphorus, nickel, copper) and small amounts of carbide-forming elements (such as vanadium, titanium, molybdenum, tungsten), on the transformation of austenite to pearlite and to bainite The difference in the influence of , thus shifting the transition curve to the right.

34CrNiMo6 is a typical difficult-to-machine material, which is widely used in the manufacture of important parts such as camshafts and connecting rods of engines. 34CrNiMo6 alloy is high strength, because of its excellent comprehensive mechanical properties, it is widely used in the manufacture of important parts such as camshafts and connecting rods of engines, and its machinability is poor, so it is a typical difficult-to-machine material. For 34CrNiMo6, its quenching and tempering process is 850 oil quenching and 580 degree tempering Classification: ① Quenched and tempered structural steel ②Surface hardened structural steel ①The carbon content of quenched and tempered steel is generally about 0.25% to 0.55%. For structural parts with a given cross-sectional size, during quenching and tempering (quenching and tempering), if they are hardened along the cross- section, the mechanical properties will be good. If it is hardened and free ferrite appears in the microstructure, the toughness will decrease. For steels with a tendency to temper brittleness, such as manganese steel, chromium steel, nickel-chromium steel, etc., they should be cooled quickly after tempering. The quenching critical diameter of this type of steel increases with the increase of grain size and alloy element content. For example, 40cr and 35simn steel is about 30-40mm, while 40crnimo and 30crni2mov steel is about 60-100mm, which are often used in the manufacture of bearing Structural parts such as shafts and connecting rods with large loads. ②Surface-hardened structural steel is used to manufacture components with hard and wear-resistant surfaces and flexible cores, such as gears and shafts. In order to make the core of the part have high toughness, the carbon content in the steel should be low, generally 0.12 to 0.25%, and there should be an appropriate amount of alloying elements to ensure proper hardenability. Nitriding steel also needs to add alloying elements (such as Al, Cr, Mo, etc.) that are easy to form nitrides. Carburizing or carbonitriding steel, after carburizing or carbonitriding at 850-950°C, quenched and used in a low- temperature tempering (about 200°C) state. Nitrided steel is used directly after nitriding treatment (480-580°C), without quenching and tempering treatment. Songshun specialized in Special Steel for almost 20 years.

12L14 is a lead-sulfur composite free-cutting structural steel. In lead free- cutting steel, lead is distributed in the steel as tiny elemental metal particles and does not solidify in the steel. During the cutting process, strong friction occurs between the tool and the workpiece, making the lead particles in the steel molten. Precipitation, thereby playing a lubricating role to improve the cutting performance of steel, making steel chips fine, reducing tool wear, and ultimately prolonging tool life. Compared with lead- free steel, the cutting performance of lead-containing steel can be improved by 20-50%, while the mechanical properties and heat treatment performance remain basically unchanged, and it has no effect on cold and hot workability and weldability. Lead free-cutting steel has been widely used in the manufacture of precision instrument parts, auto parts, and important parts of various machinery. However, lead free-cutting steel has low contact fatigue, so it is not suitable for gears, bearings and other parts that bear heavy fatigue stress loads. 12L14 has a tendency to be replaced by it. Its cutting performance is also very good. Suitable for more severe occasions where 12L14 cannot be used. characteristic 1.

12L14 is a free-cutting structural steel. Free-cutting steel is a kind of steel that is easy to be cut and processed (turning, milling, drawing, planing, drilling, etc.). It is also called steel for automatic machine tool processing, referred to as automatic steel. It is produced to adapt to mechanical processing automation and assembly line production. It is mainly used in the production of instruments and meters, watch parts, automobiles, machine tools and other various machines with small force and strict requirements on size and finish. It has strict requirements on dimensional accuracy and finish, but relatively low requirements on mechanical properties. Standard parts, such as gears, shafts, bolts, valves, bushings, pins, pipe joints, spring seat cushions and machine screw, plastic molding molds, surgical and dental surgical appliances, etc. 12L14 is a free-cutting structural steel. Free-cutting steel is a type of steel that is easily cut and processed (turning, milling, drawing, planing, drilling, etc.). It is also called steel for automatic machine tool processing, or automatic steel for short. It is produced to adapt to mechanical processing automation and assembly line production. This type of steel can be cut with a higher cutting speed and a deeper cutting amount, and the cutting resistance is reduced due to the easy-cutting elements added to the steel, and the cutting edge is lubricated due to the characteristics of the added element itself and the compound formed. The function of the part makes the chips easy to break and reduces wear, thereby improving the finish and precision of the processed parts, and improving the tool life and production efficiency.
