S690QL material number plate specification

The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing S690QL material number high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.

The advantages of S690QL material number, steel plate produced from coil: price is cheap and length can be freely determined; transportation is convenient, no need to consider according to the size of steel plate; cutting is convenient, according to the actual needs of steel plate size cutting, and finally can effectively save materials. The disadvantage of steel plate produced from coil: there will be great welding deformation during welding, which is difficult to adjust. Therefore, the steel plate produced from coil can not be used for parts with high requirements on appearance quality.

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. S690QL material number, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.

The preparation of S690QL material number galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for S690QL material number centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

S690QL material number, Q460D quenched and tempered steel plate spot specification: 6*2000*8500, 6*2000*10800, 45*1550*4900, 16*2000*9700, 14*1950*7030, 22.23*2181*12200, 28*2010*7300, 23.83*2179*5000, 19*2500*6000, 23.83*2179*5000, 28.58*2171*12300, 28.5*2340*12150, 28.58*2171*11500, 28.58*2171*10800, 22.23*2150*12200, 28.5*2000*12150, 28.58*2172*11500, 28.58*2172*10800, 28.58*2172*12100, 25.4*2298*13000 (mm).

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
