Cold drawn 42CrMo round steel is a high alloy wear-resistant material composed of a variety of alloy elements, so its self-melting property is good, and it is not necessary to remove rust when welding workpieces, and because it can be welded at a low level. A709 grade 50 structural steel sheet, 42CrMo round steel bar has good abrasion resistance, impact resistance and adhesion resistance. High temperature wear resistance, corrosion resistance and excellent performance of more than two types of composite wear.
The development A709 grade 50 structural steel sheet of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with A709 grade 50 structural steel sheet high-quality and efficient services, work together for win-win, and create a better tomorrow!
The preparation of A709 grade 50 structural steel sheet galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for A709 grade 50 structural steel sheet centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
Alloy steel plate: The primary purpose of adding alloy elements to steel is to improve the hardenability of the steel, and it is easy to obtain martensite during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are smaller, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, A709 grade 50 structural steel sheet.
Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
