SA573 Gr 70 carbon steel plate sheet common size

In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate SA573 Gr 70 carbon steel plate sheet for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 SA573 Gr 70 carbon steel plate sheet and priming gray oxide primer, and arrange shipment in time. Meet the customer urgent delivery request.

In the whole steel structure and steel body, the medium and heavy plate is an important part, once the problem occurs, it is easy to fracture, collapse and occur explosion. So how to judge whether the medium and heavy plate, SA573 Gr 70 carbon steel plate sheet is of high quality? First of all, check whether there are cracks on the surface of the SA573 Gr 70 carbon steel plate sheet plate and how glossy it is. Secondly, to measure the thickness error of medium and heavy plate, it is better to use the instrument to measure the bending tensile value. Finally, observe the scale of the steel plate manufacturers, whether there are relevant qualification certificates, and how the production process is.

High quality steel sheet and plate product SA573 Gr 70 carbon steel plate sheet supply 10.5*1970*7950, 13*1300*4350, 11*1900*12500, 12.5*2870*7100, 11*1870*12500, 10.5*1970*8000, 13*1520*7950, 11*1910*9000, 12.5*2900*8250, 11*1870*13500, 10.5*2350*6200, 14*1440*6100, 11*3100*10000, 13*1510*4850, 11*1870*9300, 11*1570*12000, 14*1800*9750, 11.5*2640*7600, 13*2380*6000, 11*2400*10000.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of SA573 Gr 70 carbon steel plate sheet etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in SA573 Gr 70 carbon steel plate sheet etc. steel is strictly controlled.
