Welding S420M material steel density

The company has the industry's advanced automated production lines and precision laboratory instruments and a capable steel industry management team. Through scientific management, optimized technology, and rigorous testing, the company will keep the production efficiency and production quality at the leading level in the industry and continue to provide customers with high-quality S420M material products. At the same time, the company is committed to building a comprehensive steel manufacturing industry and strives to make the company leads new progress and development.

At present, the company has successfully developed and produced more than 10 kinds of boron-containing steel varieties such as 35MnBM, 23MnBM, S420M material, 27MnTiB, 40MnB, 25CrMoTi, etc. According to the practice of Laiwu Steel's 50t electric arc furnace-50t LF-60t VD-R11 Lianzhuo-VD Royal alloying process development and production of boron-containing steel, the technical measures for precise control of the smelting of boron-containing steel are analyzed and discussed.

S420M material, Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.

Superior process production line advantage sdf: The company has focused on weathering steel S420M material, pressure vessel plate, oil tank plate, pipeline steel plates, and steel welded structures for many years, and has a strong factory scale; one of the domestic excellent weathering steel manufacturers, serving customers all over the world; using frequency conversion and microcomputer program control, the equipment is highly automated; Improve product efficiency and improve product quality.

Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our S420M material service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's S420M material customer service to establish a good, comprehensive, full service system.

The company attaches great importance to the value of iron and steel, constantly improving itself in terms of attitude, innovation, human resources, etc., integrating the value of iron and steel into the company's philosophy, showing the spirit of fighting for S420M material iron and steel, forging iron and steel enterprise, creating steel market, establishing iron and steel team, and attaching importance to the sustainable development of iron and steel industry, so as to make iron and steel our permanent cause.
