A203GrD steel plate belongs to ultra-low temperature container plate. ASTM A203 is a low-nickel alloy steel, including five grades A, B, D, E, and F. Among them, Grades D, E, and F have a nominal nickel content of 3.5%, commonly known as 3.5Ni steel. A203D/E/F steel has good impact toughness and mechanical properties in a low temperature environment, and is usually used in a low temperature environment of -70～-101℃ (the tempered state can reach -107℃).
In recent years, in line with the development trend of iron and A283 grade A CS steel carbon plate steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which A283 grade A CS steel carbon plate are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by A283 grade A CS steel carbon plate metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the A283 grade A CS steel carbon plate steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.
The effect of alloy elements on the properties of heat treatment methods for thick steel plate: the performance of heat treatment method reflects the difficulty coefficient level of heat treatment process and the tendency of defects caused by heat treatment process. The key points include cutting performance, over temperature sensitivity, quenching aging tendency and air oxidation carburizing tendency. A283 grade A CS steel carbon plate, Carbon steel has high machinability, and slow cooling method can be used in heat treatment, which can reduce the deformation and cracking tendency of the products. The addition of Mn and Si will increase the over temperature sensitivity of steel.
Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, A283 grade A CS steel carbon plate sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
