Main causes of subsurface bubble formation in welding hardox 450 steel

In line with the service concept of "honesty first, customer first" and the service tenet of "all for customer satisfaction", the company adopts the acceptance and response mode of combining manual and automatic, and accepts the diversified service demands of customer business consultation, complaint declaration, business acceptance, etc. through telephone, fax, e-mail, visit, letter, etc.

The main products of BBN steel are carbon steel, mild steel and low alloy steel plates. Our business scope are ASTM carbon steel, EN carbon steel, Chinese carbon steel materials, JIS carbon steel, ASME carbon steel, DIN carbon steel, etc. The main steel grades are A36, A283C, A572 Gr 50, S235JR, S355JR, SS400, Q235, Q345, welding Hardox 450 steel etc. The company has a sound quality assurance system. In order to open up the market and realize mutual benefit, we will serve our customers wholeheartedly with the business philosophy of "price, quality" and "integrity, service"

We have many kinds of boiler and pressure vessel steel materials, including ASTM, ASME, DIN, JIS, en, GB and other multinational standards, dozens of steel grades. Customers have a wide range of options. At the same time, we have obvious advantages in wide and thick plates. The widest boiler plate can be more than 5 meters. The welding Hardox 450 steel and pressure vessel steel price is also competitive, and there is a professional team to serve you.

Three advantages of semi-endless rolling technology: 1. The limit specification of Q345B steel is expanded from 1.5 mm × 1300 mm to 1.5 mm × 1600 mm. 2. the semi-endless rolling technology can effectively reduce the fluctuations in the temperature, size, and shape control accuracy of the strip head and tail. 3. The different parts of the strip steel welding Hardox 450 steel produced by semi-endless rolling have uniform structure and mechanical properties, the yield strength fluctuation is less than 40 MPa, and the tensile strength fluctuation is less than 20 MPa.

There is a silo technology R&D center in our company with many experts. Our technical backbones go abroad to study advanced technologies regularly to make our technology and products leading in the world. We provide our customers with welding Hardox 450 steel high-quality steel plates, the excellent quality from specialty. With good reputation, high-quality products, strong strength, and low prices, we welcome the clients from the world to come to visit our factory.
