The carbon and low alloy steel plates are our main products. Our main conducted standards for carbon and low alloy steel plates are (ASME) ASTM (S)A36, (S)A283, Steel A709 Grade 50 Plate, (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, , Q345B, etc.Steel A709 Grade 50 Plate,Our company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply deep processing service for products like cutting, drilling, bending, welding and grinding.Steel A709 Grade 50 Plate,Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the 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 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.Steel A709 Grade 50 Plate,Q355GNHE corten steel is characterized by adding a small amount of Cu, P, Cr, Ni and other alloying elements to the steel, so that the steel material forms a dense layer between the rust layer and the substrate with a thickness of about 50 to 100 μm and good adhesion to the substrate metal The amorphous spinel oxide layer prevents oxygen and water in the atmosphere from penetrating into the steel substrate, slows down the rust development to the steel material, and greatly improves the steel material's resistance to atmospheric corrosion,Steel A709 Grade 50 Plate.The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel. It can provide customers with drawing design, deep processing services and installation solutions. 20 years of project experience has provided high-quality carbon steel, alloy steel products and high-quality after-sales service to customers in many countries around the world. The company has won widespread praise from customers.
