The generally spoken manganese plate is low alloy high strength structural steel. This material has good weldability and can be welded by various methods. Carbon steel plate and manganese plate belong to the category of carbon structure and low-alloy structural steel. The main difference between carbon steel plate and manganese plate is that the yield strength of manganese plate is higher than that of carbon steel plate.
The fake and inferior A514 grade P structural steel material, 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.
Most common A514 grade P structural steel material steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled A514 grade P structural steel material steel plates.
Medium thick steel plate refers to the steel plate with a thickness of not less than 3 mm but less than 20 mm. It can be produced by reversible hot rolling medium and heavy plate mill, and its thin products can also be processed by cold rolling mill. A514 grade P structural steel material, Medium thick steel plates are mainly used in boilers, shipbuilding, railway cars, automobiles, containers, military industry, national defense, construction, bridges and containers.
