05CuPCrNi equivalent grades structural with low cost

The main uses of flat steel are as follows. First, flat steel is used as a raw material for processing steel plates, which is convenient for transportation, takes up a small space, and can save transportation costs. Second, 05CUPCRNI equivalent grades flat steel can be used as raw material for processing welded pipes. Flat steel can be a finished steel product, or it can be used as a billet for welded pipes and thin slabs for stacked sheets. Third, flat steel can be directly used as a steel structure. As a finished material, flat steel can be used for making hoop iron, tools and mechanical parts, and used as building frame structure and escalator in construction. Fourth, the flat steel has a smooth surface and a certain degree of beauty.

ASTM A242 has 2 grades: Type 1 and Type 2, while type 1 is the most used structural steel grade. Usually 05CUPCRNI equivalent grades it is produced to be hot rolled state, it is suitable for cutting, forming, drilling and machining, grinding.

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 05CUPCRNI equivalent grades, welded steel pipe and seamless steel pipe. The material of welded steel pipe contains the chemical composition suitable for welding.
