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. Good processing performance of easy-car iron: the product has smooth cutting, excellent material, stable processing, The metallographic structure is good, the chemical composition is stable, the deviation is small, the steel is pure and clean, and it is not easy to damage the tool; It is very easy to cut on the lathe, and the tool life and production efficiency are increased by 40%; 2. Good electroplating performance: cutting is very easy; deep holes can be drilled, deep grooves can be milled, etc.; processing efficiency Compared with ordinary steel, it can be greatly improved; the electroplating performance of the product is good, it can replace copper products, and greatly reduce the product cost; 3. Easy car iron has good smoothness: the surface finish of the workpiece after turning is good; 4. Eco-friendliness of Yichetie: It complies with the EU SGS environmental certification standard and has passed the Swiss environmental certification. Products can be exported to machinery and equipment: woodworking machinery, ceramic machinery, papermaking machinery, glass machinery, food machinery, Construction machinery, plastic machinery, textile machinery, jacks, hydraulic presses, etc.; electrical product components: motor shafts, Fan shafts, sewing machine shafts, etc.; furniture: especially export metal furniture, such as tea tables, chairs, outdoor furniture; Metal utensils: garden tools, barbecue grids, screwdrivers, anti-theft locks, etc.; small hardware parts: such as guide rails, Machine keys, nuts, screws, round nails, hexagonal nails and octagonal nails and various standard parts of different specifications; automobiles, Motorcycle spare parts and so on.

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.
