Low carbon steel S690QL spec application

The Cr-Mo alloy steel pipe fittings manufactured to ASTM A234 includes the grades of WP1, WP12 CL1, WP12 CL2, WP11 CL1, WP11 CL2, WP11 CL3, WP22 CL1, WP22 CL3, WP24, WP5 CL1, WP5 CL3, WP9 CL1, WP9 CL3, WP91, WP911, WP92. The BW pipe S690QL spec fittings can be made from either seamless pipes, or fusion-welded pipes which shall be with filler metal added and shall conform to the chemical requirements of the standard specification.

In terms of service, our service is a "one-stop" way of working. We have our own S690QL spec processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as S690QL spec cutting, welding, drilling, galvanizing, etc., at the lowest cost.

Nickel element is mainly used to form and stabilize the austenite structure, so that the S690QL spec steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.

Alloy steel plate is formed by adding alloy elements into steel. In this process, the basic elements of steel, namely iron and carbon, will have a certain effect with the newly added alloy elements. Under this effect, the structure and material in the steel will have certain changes, and the overall performance and quality of steel will also be improved. Therefore, the output of S690QL spec, alloy steel plate is increasing, and its application range is more and more extensive.

We are willing to cooperate sincerely with you with high-quality S690QL spec products and sincere service to expand the market and create brilliant! We will work hard to create a first-class steel company and provide you with faster and more considerate after-sales services! Moreover, our shipbuilding steel plates have been certified by the nine countries' classification societies including DNV, ABC, GL, LR, BV, CCS, RINA, NK, and KR. The quality assurance system has passed ISO9001-2000 standard certification.
