SM400C carbon steel plate sheet price is expected to reach peak in the third quarter

Q355NHE grade is a weather-resistant structural steel used in construction, bridges, and railway vehicles. Q represents yield strength, NH represents weather resistance, and E represents quality grade (A, B, C, D, E) composition. Q355NHE is an atmospheric corrosion-resistant steel plate, also called weather-resistant steel plate. It has the properties of high-quality steel such as strength, ductility, forming, welding, abrasion, high temperature, and fatigue resistance.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium SM400C carbon steel plate sheet carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some SM400C carbon steel plate sheet alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.

Phosphorus is a very harmful element in SM400C carbon steel plate sheet steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of SM400C carbon steel plate sheet steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
