Non-secondary hot rolled hr plate hardox 400 suppliers 28mm plate price

Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, HARDOX 400 suppliers included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.

Facing the new situation and facing new goals, the company revolves around the sixteen-character development policy of “prioritizing production preservation, society-oriented, market operation, and brand creation and efficiency”. Layout the country in accordance with the modern logistics model, and accelerate the establishment of a modern integrated steel enterprise integrating steel storage, transportation, processing, and distribution.

Most common HARDOX 400 suppliers 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 HARDOX 400 suppliers steel plates.
