How to select the qualified S690QL1 steel plate

Superior process production line advantage sdf: The company has focused on weathering steel S690QL1 steel plate, pressure vessel plate, oil tank plate, pipeline steel plates, and steel welded structures for many years, and has a strong factory scale; one of the domestic excellent weathering steel manufacturers, serving customers all over the world; using frequency conversion and microcomputer program control, the equipment is highly automated; Improve product efficiency and improve product quality.

The method of distinguishing manganese plate from common carbon steel plate, S690QL1 steel plate is as follows:(1) Check the spray labelWhether it is manganese plate or common carbon steel plate, it has its own factory spray mark, just check it;(2)Listen to the cutting soundThe cutting sound of manganese plate is relatively clear and crisp, while that of common carbon steel plate is not clear and crisp, and the manganese plate will fall off as soon as it is cut;(3) Look at the polishing sparksLook at the amount of sparks on the surface during polishing. The more sparks and forks are manganese plates, and the lesser ones are common carbon steel plates;(4) Check the material certificateGenerally, the material certificate will clearly indicate what material it is, just check it.

Since it was established in 2000. Based on the domestic rich S690QL1 steel plate product resources and the great steel demand of the international market, our S690QL1 steel plate service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products

The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of S690QL1 steel plate, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.
