On March 19, 2020 the us international trade commission (ITC) vote on imports from China and India's carbon alloy RF 40 hull structure ship steel plate steel screw (Carbon and Alloy Steel Threaded Rod) to make a positive final anti-dumping and anti-subsidy industry damage. All five members of the international trade commission voted in favor of the ruling. The us department of commerce will issue anti-dumping and countervailing duty orders on imports of RF 40 hull structure ship steel plate carbon alloy steel screws from China and India, according to the itc's affirmative ruling.
Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.
our company offered 2950 ton A36 steel RF 40 hull structure ship steel plate plate to Philippines customer, which was used to build water supply project. It is the government project. The procurement with their project engineer come to China to discuss this project in middle of 2016. After checking the mill, they signed the contract with us. we supply the ASTM A36 Original Mill Test Certificate Stamped.
The visual inspection (VI) or visual detection method is to scan the surface of the steel plate through a machine vision system (CCD line camera), convert the captured target into an image signal, and send it to a dedicated image RF 40 hull structure ship steel plate processing system, which converts it into a digital signal based on pixel distribution and brightness, color and other information. The system performs various operations on these signals to extract the characteristics of the target, and then controls the operation of the equipment on the spot according to the result of the discrimination. Visual detection method can achieve online high-speed detection for the RF 40 hull structure ship steel plate steel plate.
The wear-resistant layer of RF 40 hull structure ship steel plate 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 RF 40 hull structure ship steel plate carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.
Product concept: take the technology leading as the pillar of the enterprise, achieve the development goal of the enterprise with the reliable products, the reliable technology and the trustworthy services, and devote to the creative reform activities leading in the technical development and career of the industry to create new value through continuous change.
