5mm S690QL steel hardness price list

The toughness index of Q345B steel should be tested by impact test at 20 ℃. Although the strength of Q345B steel and Q345A steel are the same, the S / P control of Q345B steel is more strict, and the ambient temperatures of S690QL steel hardness, Q345B steel and Q345A steel are different. The cold impact test refers to the impact test at a certain temperature to obtain the energy consumed by punching the specimen. The more energy consumed, the higher the toughness of the material. Q345A is not subject to impact test. So Q345B steel is better than Q345A steel.

After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, S690QL steel hardness tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of S690QL steel hardness steel and 542,000 tons of steel.

Looking to the future, our company will make its main business more competitive while carrying out diversified, extensive, green and harmonious development modes, so as to be the most competitive S690QL steel hardness producer in the world as well as a worldwide first-class enterprise. With ten years cooperation with these big mills, now we are the agent of super stainless steel mills in China.
