30CrNi3MoV (675) high-strength steel is a new type of high-strength steel newly developed and put into use in China. It is a steel plate for armored vehicles. 30CrNi3MoV steel is developed by V microalloying on the basis of the original Cr-Ni-Mo series low-alloy ultra-high-strength steel, and appropriately adjusting the content of other alloying elements. The milling performance of 30CrNi3MoV steel is poor.
Generally, the steel plates for boiler and pressure are divided into categories. A516 gr60 carbon steel plates have a maximum thickness that varies on the capacity. The tensile strength, elongation, yield strength, and hardness are the mechanical properties of these plates. Physical and chemical characteristics of the boiler quality plates GL-A hot-rolled steel strip make these a popular choice in the industries. Also, these carbon steel are made up of premium quality raw materials by the use of the latest machinery and are therefore of robust built.
The preparation of GL-A hot-rolled steel strip 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 GL-A hot-rolled steel strip centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
