2 inch nm500 steel equivalent grades heavy plate prime quality

Hot-rolled coil is a commonly used steel product in the industry. It has a relatively wide variety of products and a wide range of uses. NM500 steel equivalent grades, Hot-rolled coils are widely used in related industries such as petrochemical equipment, automobiles and bridges. Hot-rolled coils are also used in machinery industries such as ships and automobiles because of their good toughness and relatively high strength.

In 2019, through the concerted cooperation of the enterprise team, the sales volume has grown steadily, and the annual sales volume has exceeded 300 million yuan. For this reason, both the investors and employees of the enterprise have received satisfactory returns. With strong development potential and brand advantages, we have always been committed to "integrity, efficiency, pragmatism, dedication" corporate spirit, dedication to society, and return to the public. From this perspective, the enterprise will have a bright future. In a good environment with strong hardware facilities and excellent management personnel, we can make sure that the company will develop stronger and bigger.

The carbon content of NM500 steel equivalent grades, hot rolled steel plate is slightly higher than that of cold rolled steel plate. Hot rolled steel plate has low hardness, easy processing and good ductility. Cold rolled steel plate has high hardness and is difficult to process, but it is not easy to deform and has high strength. The strength of hot-rolled steel plate is relatively low, the surface quality (oxidation finish) is low, but the plasticity is good, and it is generally medium thick plate.

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, NM500 steel equivalent grades 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.
