What are the top 3 nm500 plate thickness size hot rolled plates mills in UAE

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of NM500 plate thickness size, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

The structure of NM360 wear-resistant steel plate: The test found that whether it is a grinding ball, a forehead plate, or a hammer, after casting, it can get a structure based on wear-resistant steel after taking out air cooling at a temperature greater than 850℃. Transmission electron microscopy analysis of the metal thin film shows that there is a high density of dislocations in this type of wear-resistant slats, and there is an austenite film between the slats. Due to the high carbon content in this austenitic film, it has high stability. It is the shape of the NM500 plate thickness size, wear-resistant plate that makes the steel have a good combination of strength and toughness.

Oxygen is a harmful element in NM500 plate thickness size steel. With the increase of oxygen content, the strength of NM500 plate thickness size steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of NM500 plate thickness size steel.

The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
