What is chemical composition of A572 Gr 42 carbon steel plate sheet

The thickness of our pressure vessel plates, A572 Gr 42 carbon steel plate sheet generally ranges 5 to 200mm. According to the working conditions and processing technology of the container, the pressure vessel plate must have good cold bending and welding performance; good plasticity and toughness; high temperature short-term strength or long-term strength performance. In order to make the container can withstand higher pressure and reduce the weight of the structure itself, in addition to high-quality carbon steel, pressure vessel plate is currently made of low-alloy structural steel.

The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.

The preparation of A572 Gr 42 carbon steel plate 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 A572 Gr 42 carbon steel plate sheet centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

A572 Gr 42 carbon steel plate sheet, 45# steel is widely used in mechanical manufacturing, and its mechanical properties are very good. But 45# steel is a kind of medium carbon steel, the quenching property is not good, 45# steel can be hardened to HRC42 ~ 46. Therefore, if the surface hardness is required, and the superior mechanical properties of 45# steel are expected to be exerted, the surface of 45# steel is often carburized and quenched, so that the required surface hardness can be obtained.

The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel A572 Gr 42 carbon steel plate sheet plates. It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system. BBN company provides customers with solutions at low prices, high quality, and fast response service.
