B55SiCr bright bar is a high-performance material. Its surface is bright and smooth, and its appearance quality is good. In terms of performance, it has high strength, high tensile and yield strength, and can withstand large loads and stresses. It has excellent elasticity and can recover quickly after deformation under force, making it a good choice for making springs. It has good toughness and is not easy to break in the face of impact and complex stress, which improves the safety and life of use. It has good hardenability, and the internal hardness and strength are evenly distributed during quenching. In addition, it has good wear resistance, corrosion resistance and oxidation resistance, and can work in harsh environments. It is widely used in the industrial field.

Chemical element content (%)

Specification：1.00~300.00mm

Compared with other brands of B55SiCr bright bars, what are the advantages of Sividen's B55SiCr 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 B55SiCr 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 B55SiCr 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, B55SiCr 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 B55SiCr 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 B55SiCr 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.
