The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel. The company is a modern enterprise integrating scientific research and development, production processing, sales and service. Our main products include hot rolled plates, seamless pipes, A709 grade 50W low alloy steel sheet and steel structures. At the same time, it also adheres to international standards and adheres to the international line.
Q355NH steel plates and sheets with atmospheric corrosion resistance are mainly used for vehicles, bridges, containers, buildings, towers, and other structures. Weather-resistant steel can be used to make bolted, riveted and welded structural parts. We can also slit and sheet Q355NH (Equivalent A588 steel) to any weight and size for immediate delivery. Our A709 grade 50W low alloy steel sheet, Q355NH weathering steel plates are produced with thickness up to 100mm.
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the A709 grade 50W low alloy steel sheet steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This A709 grade 50W low alloy steel sheet method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.
P235GH steel material number under EN10028-2:2003 standard is 1.0345. This steel is a European pressure vessel steel. P235GH Mechanical properties: Tensile strength σb (350 ~ 480 MPa); Yield strength σs(215 MPa min.); Elongation ≥25%; Brinell hardness ≤105 ~ 140.
