The role of chromium in normalized ABS grade E hull steel plate

Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the normalized ABS grade E hull steel plate steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This normalized ABS grade E hull steel plate method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.

In 2015 , We get the tender from Myanmar Government, the total quantity is 1200 ton ABS-AH36 steel plate, we supply the steel plate with painting ( which standard is according to ISO SA2.5) with gray Color 20 Micron. After Get Customer Contract, Steel Plate Are Produced within 25 days .Then, Goods transported to Tianjin Port And Shipping On Time To Statisfy With Project Expected After Finished Producing. The Steel Quality normalized ABS grade E hull steel plate we offered receive good Praise from our Customers .

Welded steel pipes are made by crimping steel plates, bending them into a circle, and then welding the joints together. Seamless steel pipe is directly processed by round steel piercing or hot rolling process, so there is no weld on the outer surface. The performance of seamless steel pipe is better than that of welded steel pipe, and the price of seamless steel pipe is also higher. There are some differences in chemical composition between normalized ABS grade E hull steel plate, welded steel pipe and seamless steel pipe. The material of welded steel pipe contains the chemical composition suitable for welding.
