Carbon structural steel refers to the kind of steel which is mainly used in construction and engineering structures without adding alloy elements. Among all kinds of steel, A514 grade B alloy steel plate, carbon structural steel has a large output, the most extensive use and low price. Carbon structural steel is often rolled into various steel bars (round steel, square steel, flat steel, hexagonal angle steel, etc.), section steel (I-beam, angle steel, channel steel, L-shaped steel, etc.), profiled steel and steel plate. Carbon structural steel is mainly used in buildings and engineering structures such as workshops, bridges, ships, etc. Generally, heat treatment is not required for carbon structural steel.
The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for A514 grade B alloy steel plate pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common A514 grade B alloy steel plate carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.
A514 grade B alloy steel plate, 27SiMn material has high strength and wear resistance, high hardenability, medium plasticity during cold deformation, good machinability and fair weldability. It is mostly used after quenching and tempering, and can also be used in normalizing or hot rolling state. 27SiMn material chemical elements: C: 0.24-0.32, Si: 1.10-1.40, Mn: 1.10-1.40. 27SiMn material mechanical properties: tensile strength 980 MPa; yield strength: 835 MPa; elongation after fracture: 12%; impact energy: 39J. 27SiMn material can be used to make hot stamping parts with high toughness and high wear resistance, which do not need heat treatment or normalizing, such as tractor track pins.
As we all know, steel pipes occupy more space in the process of transportation. If there is no good way of packing, the transportation cost for steel pipes will be a big expense. In view of this characteristic, our company is ingenious and adopts the nest package method to solve this problem perfectly. The premise of the nest package is that the diameters of the steel pipes are different, and the small diameter pipe is inserted in the large diameter pipe. This not only saves the volume, but also saves the transportation cost. It also reduces the loading and unloading workload by half, saves precious time, and enables customers to receive goods earlier.
The strip steel thickness is generally below 6mm, which is convenient for crimping and processing. You should choose the A514 grade B alloy steel plate, strip steel specifications according to your own purposes. The specifications and materials used for different purposes are different, so you must confirm it before buying. It is best to ask professionals to give advice before purchasing strip steel, and purchase the specifications and types you need according to the corresponding requirements.
