Welcome to BBN High Strength Steels Factory

welding of S690QL H beams

A709Gr.36 steel plate is used in construction steel structures, construction machinery and other steel structures, and has been exported to South Korea, Singapore, Malaysia, Dubai, Nigeria and other countries. The welding of S690QL) cumulative export volume has reached more than 10,000 tons. Construction steel structure, construction machinery, mining and mountain machinery, trucks, bridges, pressure vessels, especially for construction and engineering machinery parts that require good weldability and toughness.

We are world class steel materials supplier. We are engaed in providing raw steel materials such as welding of S690QL steel plates / steel coils / steel sheets / steel pipes, deep processing and a series project design and solutions to clients. We guarantee to return goods for free for quality problem during its lifetime. Your satisfactory is our permanent pursue. We always welcome advise from clients to make self-improvement continously. And sincerely to build welding of S690QL long-term cooperation with you.

In the production process of the ironmaking process, the moisture content and air temperature of the ironmaking blast furnace blast have a direct impact on the fuel consumption and fuel consumption structure of the ironmaking process. Blast furnace blast dehumidification is to remove the moisture in the blast furnace blast, eliminate the adverse effects of atmospheric humidity fluctuations on the blast furnace forward movement, and create stable operating conditions for the fans.

Alloy elements have the most significant strengthening effect on steel in quenched and tempered state. The primary purpose of adding alloying elements to steel is to improve the hardenability of steel and to ensure that martensite is easily obtained during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, welding of S690QL.

Our company will accept the product quality objection registration record, pass it to the welding of S690QL production unit and relevant departments, and timely coordinate the supervision of product welding of S690QL quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
