Our main conducted standards for carbon and low alloy steel plates are (ASME) ASTM (S)A36, (S)A283, EN 10025 S690QL high strength steel, (S)A572, (S)A573, (S)A633, (S)A709, EN10025-2, EN10025-3, EN10025-4, EN10025-6, JIS G3101, JIS G3106, DIN 17100, DIN 17102, etc. Our typical carbon and low alloy steel grades are (S)A36, (S)A283 grade C, (S)A572 grade 50, S235JR, S355JR, S355J2, SS400, SM570, ST37-2, ST52-3, Q235B, EN 10025 S690QL high strength steel, Q345B, etc.

Q235NH corrosion-resistant steel plate full name: atmospheric corrosion-resistant hot continuous rolled steel, also known as Corden steel, widely used in: containers, power plants, chimney and railway engineering, such as large outdoor sculpture steel. The corrosion-resistant steel plate (i.e. atmospheric corrosion resistant steel) is a low-alloy steel series with low price and good quality, which is between ordinary steel such as EN 10025 S690QL high strength steel and stainless steel. The corrosion-resistant steel can be continuously developed and innovated after being integrated into modern metallurgical new mechanism, new technology and new process. It is one of the series of steel with world advanced super steel technology.

Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This EN 10025 S690QL high strength steel method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.

The company specializes in hot rolled plates producing, steel plate processing, steel plates cutting, carbon steel plate weldding and exporting of wide and thick steel plates. BBN company has high-quality CNC EN 10025 S690QL high strength steel steel plate cutting processing equipment, professional technical personnel, and supporting marketing and after-sales service system.
