Welded st37 S690QL placa de acero good property

Based on the main st37 S690QL placa de acero business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel st37 S690QL placa de acero products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Steel transportation because of the special material of st37 S690QL placa de acero steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.

Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the st37 S690QL placa de acero steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the st37 S690QL placa de acero weathering steel is purified and the content of inclusions is greatly reduced.

BBN steel had provided Grind plates for more than 15 years for widely applied in equipment, Engineer machinery etc. In 2018, one of our India customer visit our st37 S690QL placa de acero office and work shop to discuss Q235B Grind plate technical request, they have strict surface and thickness tolerance, and they also request UT and MT for testing. As a result, they purchase st37 S690QL placa de acero 179 tons as trial order for first cooperation. And have good comment on our quality. Till now, we keep exporting around 100 tons per month as regularly.

The quality grade of common carbon structural steel Q235 can be divided into A, B, C, D and E. Relatively, the quality of Q235A is poor and that of Q235E is the highest. Different grades of Q235 steel have different characteristics, which are mainly different from the impact temperature: Q235A does not require impact toughness test; grade Q235B is for room temperature (20℃); grade Q235C is for 0℃; grade Q235D is for - 20℃; grade Q235E is for - 40℃. The st37 S690QL placa de acero, carbon structural steel Q235 has good combination of strength, plasticity and welding properties.
