BEBON cpompany practice new development concepts, expand in an all-round way, deepen reform and innovation, speed up transformation and upgrading, become stronger, better and bigger, accelerate the implementation of BEBON Steel's A572 grade 55 ms steel coil industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate A572 grade 55 ms steel coil market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.
The company has a group of mature steel plate production and processing line construction and production management experience. In addition, the company has professional and technical personnel. BBN steel is a modern enterprise integrating scientific research and development, production processing, sales and service. The company now has finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. At the same time, it also adheres to international standards and adheres to the international line.
The ASTM A572 A572 grade 55 ms steel coil specification refers to high-strength low-alloy steel plates used in structural buildings. Among the five steel grades 42, 50, 55, 60 and 65, grade 50 is the most common in applications requiring higher strength and lighter weight. One of the A572 grade 55 ms steel coil steels, the steel plate of this brand other than ordinary carbon steel is used, so that the steel structure has the same steel strength, but the weight is lighter.
The advantages of A572 grade 55 ms steel coil, seamless steel pipe are high pressure resistance, good toughness, long pipe section and few joints. It is widely used and the rolling technology of domestic steel mills is also very mature. Compared with round steel, the weight of seamless steel pipe is lighter under the same strength. Seamless steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, save materials and processing time. Compared with the welded pipe, there is no weld on the outer surface of seamless steel pipe, and it has good compression resistance.
Chemical composition of Q420 steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420 steel are: yield strength ≥ 340 MPa, tensile strength 500-680 MPa, elongation after fracture ≥ 18%, impact energy 34J. A572 grade 55 ms steel coil, Q420 steel has good mechanical properties and weldability, good cold and hot workability. Q420 steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.
Our company will accept the product quality objection registration record, pass it to the A572 grade 55 ms steel coil production unit and relevant departments, and timely coordinate the supervision of product A572 grade 55 ms steel coil quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
