12L14 steel plate: an outstanding representative of high-performance free-cutting steel
In the field of modern industrial manufacturing, the performance of steel directly affects the quality and production efficiency of products. As a high-performance free-cutting structural steel, 12L14 steel plate has become an ideal choice for precision machinery, automotive parts, electronic equipment and other industries with its unique chemical composition and excellent processing characteristics.
1. Chemical composition: the core of excellent performance
The special performance of 12L14 steel plate comes from its carefully formulated chemical composition. The carbon content is strictly controlled at ≤0.15%, which ensures the toughness and ductility of the material; the higher manganese content (0.85 – 1.15%) enhances the strength and wear resistance; and the silicon content is ≤0.10%, which reduces the interference of impurities on performance. In addition, the addition of phosphorus (0.04 – 0.09%) and sulfur (0.26 – 0.35%) significantly improves the cutting performance; the addition of lead (0.15 – 0.35%) further reduces the cutting resistance, making the chips easier to break, and effectively improving the processing efficiency and tool life.
II. Performance advantages: taking into account both processing and application
1. Excellent cutting performance: 12L14 steel plate can be called “a friendly partner for mechanical processing”. Its cutting resistance is more than 30% lower than that of ordinary steel. It can achieve high-speed cutting and large feed processing. It performs well on automatic lathes, CNC machine tools and other equipment, greatly shortening the processing cycle and reducing production costs.
2. Good surface quality: The surface finish of the processed 12L14 steel plate can reach Ra0.8-1.6μm. No complicated subsequent polishing treatment is required. Electroplating, spraying and other surface treatment processes can be directly carried out, which not only ensures the appearance of the product, but also improves production efficiency.
3. Stable mechanical properties: The tensile strength of the steel plate is in the range of 380-460MPa, the elongation is 20-40%, the cross-sectional shrinkage is 35-60%, and the hardness is moderate (hot-rolled state 121HB, cold-rolled state 163HB). It can maintain stable mechanical properties under various working conditions and meet the use needs of different scenarios.
4. Environmental protection and safety: 12L14 steel plate strictly follows international environmental protection standards, has passed the EU SGS environmental certification and Swiss environmental certification, does not contain harmful substances such as lead and mercury, and is in line with the development trend of modern green manufacturing.
III. Specifications and standards: Adapt to multiple needs
12L14 steel plate has a wide range of applicability in specifications. The thickness range of hot-rolled steel plate is 1-180mm, the thickness of cold-rolled steel plate is 0.1-4.0mm, the conventional width is 1220mm, and the length is 2440mm, which can be flexibly customized according to customer needs. In terms of standards, it corresponds to international standards such as AISI 12L14 in the United States, SUM24L in JIS G4804 in Japan, and 10SPb20 (1.0722) in DIN EN 10087 in Germany, ensuring the versatility and interchangeability of products in the global market.
IV. Application fields: Empowering industrial upgrading
1. Automobile manufacturing: used to produce precision parts such as gearbox gear shafts, fuel injector housings, sensor brackets, etc., to ensure the efficient operation of automobile power systems and electronic control systems.
2. Electronics and precision instruments: It is the preferred material for manufacturing high-precision products such as watch gears, medical surgical instruments, and optical instrument adjustment screws, helping electronic equipment and precision instruments to achieve miniaturization and high precision.
3. Mechanical manufacturing: It plays a key role in the manufacturing of parts such as hydraulic valve cores, bearing retainers, and connecting pins of automation equipment, and improves the stability and durability of mechanical equipment.
4. Daily necessities and consumer goods: It is widely used in high-end furniture hardware, locks, electronic product micro-axles and other products, taking into account functionality and aesthetics.
As a high-quality steel that integrates high performance, easy processing, and environmental protection, 12L14 steel plate is driving the modern manufacturing industry to move towards high efficiency, precision, and green with its unique advantages, and has become an important cornerstone for many industries to achieve technological breakthroughs and product innovation.
