Main business: carbon steel plate cutting, round steel cutting, stainless steel cutting, round pipe cutting, A283 grc steel sheet, steel structure welding. It can also cut various machine tool side plates, special-shaped parts, flanges, bearing seats, bearing supporting bases, embedded parts, counterweights, rolling stands, cutting squares, cutting circles, etc. according to customer drawings. BBNsteel company has good business channels with major steel mills, and undertakes all kinds of steel plate processing services.
The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. A283 grc steel sheet, Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.
Our quality control department will do inspection for details of the steel materials A283 grc steel sheet before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of A283 grc steel sheet, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.
