20Cr bright bar is a high-quality alloy structural steel bar. Its surface presents a bright appearance and high finish. 20Cr bright bar has both high strength and can withstand large loads, and good toughness. It is not easy to brittle fracture under impact loads, which can ensure the safety of parts under complex working conditions. During cold processing, its cold heading, cold drawing and other process performances are good, and it is easy to be processed into precision parts of various shapes and sizes, and the surface quality of the processed parts is high and the dimensional accuracy is good. In terms of hot processing, its forming effect is good under forging, rolling and other operations, and it can be shaped into products of various shapes and specifications according to different design requirements, showing excellent plasticity and forgeability. 20Cr bright bar is the key force to promote the efficient and stable development of modern industry.

Compared with other brands of 20Cr bright bars, what are the advantages of Sividen's 20Cr bright bars?
1. High quality stability: Advanced and strict production process and quality control system, strict control from raw material screening to production in all links, very precise control of chemical composition, can accurately control the content of various elements such as carbon, silicon, manganese, etc., to meet the standard requirements, to ensure the mechanical properties and quality stability of 20Cr bright bar. The performance and quality fluctuations of Sividen bright bar are very small, which can meet customers' high requirements for product consistency and provide reliable guarantee for subsequent processing and use.
2. Excellent surface quality: The use of advanced production equipment and processing technology makes the surface smoothness, flatness and finish of 20Cr bright bar very high. Smooth surface can not only reduce friction in subsequent processing and improve processing efficiency, but also reduce stress concentration caused by surface defects and extend the service life of the product. The surface treatment process is optimized during the production process, so that the surface of the bright bar has better corrosion resistance. In some environments with high requirements for corrosion resistance, 20Cr bright bar can maintain good performance and is not easy to rust and corrode.
3. High dimensional accuracy: Advanced production equipment and precision testing instruments can accurately control the size of 20Cr bright bar, making its dimensional tolerance range smaller, which can meet customers' requirements for high-precision dimensions. Not only is the dimensional accuracy of a single product high, but the dimensional difference between bright bars in the same batch is also very small, with good dimensional uniformity. For some products that require batch processing, this can ensure the dimensional consistency of each part, improve production efficiency and product quality.
4. Rich product variety: According to market demand and customer's special requirements, customized 20Cr bright bar products are provided to meet the use requirements under various complex working conditions, providing customers with more choices.
5. Perfect after-sales service: The perfect after-sales service system can respond to customer needs and feedback in a timely manner. For problems encountered by customers during use, technical support and solutions are provided to customers quickly.
