Our company is a large A573 Gr 70 CS steel carbon plate steel enterprise integrating steel plate production, sales and processing. It is a first-class agent of Shanxi Taigang, Shanghai Baosteel, Jiugang, Xi'an Huaxin, Taishan steel, Dongfang special A573 Gr 70 CS steel carbon plate steel and southwest special steel. It is a special dealer of famous steel plants in China, such as Columbus, NAS, acerinox, Outokumpu, Arcelor, nipponmetalindustry, nipponyakinkogyo, NSC, etc.
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, A573 Gr 70 CS steel carbon plate is of high quality? First of all, check whether there are cracks on the surface of the A573 Gr 70 CS steel carbon plate 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.
The surface quality of pickling coil is very good. Compared with ordinary hot-rolled plate, A573 Gr 70 CS steel carbon plate, the surface quality of hot-rolled pickling coil is improved in addition to the oxide scale on the surface, which is convenient for welding, oiling and painting. The accuracy of pickling coil specification is high. After leveling, the shape of the plate changes to a certain extent, thus reducing the deviation of unevenness, improving the surface finish and enhancing the appearance effect of pickling coil.
Non-destructive flaw detection of steel plates is a test method for inspecting the A573 Gr 70 CS steel carbon plate surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used A573 Gr 70 CS steel carbon plate steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.
"ASTM A516 Grade 70 plate is a boiler / pressure vessel quality of steel plate for use in low to moderate services. It has improved notch toughness. A573 Gr 70 CS steel carbon plate, A516 Grade 70 steel plates can be produced with thick up to 200mm.For boiler steel plate A516 Grade 70, the yield strength shall be above 260 Mpa, tensile strength from 485 Mpa to 620 Mpa.A516 Garde70 steel plate is equivalent to the P355GH and 490B grades. "
We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
