Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of CCSB bulk cargo ship steel service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.
The wear-resistant layer of CCSB bulk cargo ship steel wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy CCSB bulk cargo ship steel carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.
The location weld of CCSB bulk cargo ship steel, wear-resistant steel plate is only allowed to be welded on the base metal surface with the electric welding rod for welding the base metal; in the welding of the base course, the base weld shall be strictly prevented from melting to the transition layer or even the multiple layer weld of stainless steel, so as to prevent a small amount of high chromium and high nickel surfacing wear-resistant steel plate components diluted into the carbon steel weld to form martensite structure and harden.
our company supplied 2300 ton API 5L GrB ERW pipe to Petroleum company in 2016. It takes 35 days for our company to finish all the production according to API 5L standard. The products are used to drilling , gas transmission works. And we supply the API5L PSL1 GR B original Mill Test Certificate, API5L PSL1 GR B pipes picture, the dimension test, the CCSB bulk cargo ship steel material, heat number, supplier name and size will be shown on the surface of steel pipe.
