The fake and inferior SA588 Grade A, Grade B, Grade K structural alloy steel, steel plates have no metallic luster and are light red or similar to pig iron for two reasons. 1. Its blank is adobe. 2. The rolling temperature of counterfeit and inferior materials is not standard, and their steel temperature is visually inspected. In this way, rolling cannot be carried out in the specified austenite area, and the performance of the steel plate will naturally not meet the standard.
Specification range of available steel SA588 Grade A, Grade B, Grade K structural alloy steel: thickness ≤ 650mm, width ≤ 4500mm, length ≤ 18000mm. Larger specifications of steel plates are also available as required. Our steel plates SA588 Grade A, Grade B, Grade K structural alloy steel can be supplied according to Chinese standard, American Standard AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, international ISO and other standards. Heat treatment process: controlled rolling, normalizing, tempering, normalizing plus tempering, quenching and tempering, etc.
Q345 is a steel material. It is a low alloy steel, with good comprehensive properties, low temperature properties, cold stamping properties, SA588 Grade A, Grade B, Grade K structural alloy steel welding properties and machinability. Q345 steel is subdivided into Q345A, Q345B, Q345C, Q345D and Q345E. This is the grade distinction, which represents that the impact temperature is different! Q345A, no impact; Q345B, impact at 20 degrees normal temperature; Q345C, impact at 0 degrees; Q345D, impact at - 20 degrees; Q345E, impact at - 40 degrees. At different impact temperature, the impact value is different.
The company adopts the SA588 Grade A, Grade B, Grade K structural alloy steel international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety SA588 Grade A, Grade B, Grade K structural alloy steel management system, and has realized the comprehensive integration of the three systems.
