Common grades of carbon structural steel plates: A36, A283Grade C, A572Grade 60, A573Grade 70, Q235B, Q235C, S235JR, S275J0, SS400, St37-2, A514 grade B alloy steel plate, St52-3. Our company can provide carbon structural steel plate thickness ranging from 6 to 300mm. These plates are widely used in various types of engineering structures such as steel structure buildings, construction machinery, heavy vehicles, bridges, pressure vessels. Besides, we can provide Q235B carbon steel plate with Z direction test.
Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for A514 grade B alloy steel plate various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several A514 grade B alloy steel plate after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.
The toughness of steel such as A514 grade B alloy steel plate is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.
Laser cutting A514 grade B alloy steel plate has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the A514 grade B alloy steel plate cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.
