Over the years, the company has established a standard of S460 steel plate steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to S460 steel plate quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.

The S460 steel plate, thin steel plates are more convenient for cutting. Since the thickness of the thin steel plate is basically below 4mm, it is very easy to construct during cutting, which also reduces the work intensity of the construction personnel and speeds up the work efficiency of cutting. There are different materials for thin steel plates, such as ordinary carbon steel, high-quality carbon structural steel, alloy structural steel, carbon tool steel, stainless steel, spring steel, silicon steel for electrical engineering, etc..

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized S460 steel plate are higher than that of annealed S460 steel plate, but the elimination of internal stress is not as good as annealing. The normalizing operation of S460 steel plate is simple, the cost is low, the productivity is high, and it is widely used in actual production.

Although Q345E steel plate has stronger torsion resistance and better corrosion resistance than ordinary steel plate, there are still some environments that can cause corrosion to Q345E steel plate. The following environment should be avoided as far as possible to avoid corrosion of S460 steel plate, Q345E steel plate. 1. Acid water. 2. Salt water. 3. Nitric acid. 4. Atmospheric erosion. Atmospheric erosion for Q345E steel plate corrosion is reflected in the chloride and pollutant pollution source of Q345E steel plate corrosion, this corrosion is very serious.
