A572 gr42 steel plate is a kind of main precision steel structure and normalizing steel. A514 grade R alloy steel plate, ASTM A572 gr42, 50, 55, 60, 65 is a kind of high strength low alloy steel plate, which is widely used in factory construction, general buildings and various construction machinery, such as mining and various construction drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, hydraulic supports, mining machinery and other structures.
The fake and inferior A514 grade R alloy steel plate, 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.
Company through its own A514 grade R alloy steel plate website, multimedia, radio, newspapers, the group, the handbook of the corporate culture carrier, approved and publicity column, in-depth to carry out enterprise culture construction, also through photography, painting, calligraphy, cartoon, speech, and the songs of the enterprise design, various cultural and sports activities to carry out enterprise culture construction.
The most commonly used material for open slabs is steel. Open slabs made of steel have high hardness. Pig iron has a very high hardness, but the plasticity of pig iron slabs is not high. It A514 grade R alloy steel plate can only be used for construction and simple machinery.
