40CrVS bright bar is a high-quality alloy structural steel material. It has a uniform and bright appearance and a smooth surface without defects. In terms of performance, 40CrVS bright bar has high strength and toughness. After appropriate heat treatment, it can withstand large loads without breaking easily, and it can also show good impact resistance when impacted. The material also has good hardenability, which can obtain relatively uniform hardness and strength on a larger cross section. 40CrVS bright bar has good cutting performance, which is convenient for various machining operations and can meet the manufacturing of parts with different shapes and precision requirements. In addition, it also has certain wear resistance and corrosion resistance, which is suitable for use in more complex working environments. It has become an important choice for many industries with its excellent performance and reliable quality.

Chemical element content (%)

Specification：1.00~300.00mm

Application: Mainly used for manufacturing gears, shafts, worms, spline shafts, collars, knuckles, half shafts, camshafts, valves, pump shafts, pipe connectors, etc.; widely used in machinery manufacturing, automobile industry, petrochemical industry and other fields.

Compared with other brands of 40CrVS bright bars, what are the advantages of Sividen's 40CrVS 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 40CrVS 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 40CrVS 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, 40CrVS 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 40CrVS 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 40CrVS 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.
