Hot Rolled Metal Iron SPHC 1-4mm Pickled Oiled Mild Iron Oiled Carbon Steel Coil Ship Use For Building Material

The main uses of hot-rolled pickling in the automotive industry are as follows: automotive chassis systems, including beams, auxiliary beams, etc. Wheels, including rims, wheel radiation, etc. Cabin board. The compartment board is mainly the compartment floor of various trucks. Other stamping parts, including anti-collision bumpers, brake sleeves and other small internal parts of automobil.

What is the difference between pickling plate, cold rolled plate and hot rolled plate?

1. Different concepts

Pickling plate is hot rolled plate through the removal of phosphorus (out of the hot rolling process rust, residue, etc.) and other processes with pickling surface to get better than hot rolling surface performance of steel plate. Cold rolled plate is the steel plate rolled by cold rolled base plate (hot rolled plate) at normal temperature. Due to the high stress of cold rolled plate, it generally needs to go through annealing process. Hot rolled plate is a steel plate made of steel billet rolled at a high temperature of about 800 degrees.
2. Different production techniques

Pickling plate is an intermediate product between hot rolled plate and cold rolled plate after removing the oxide layer by pickling unit, cutting edge and finishing. In general, cold-rolled steel plates have better strength and hot-rolled steel plates have better ductility. Hot rolled steel is rolled at high temperature, cold rolled at room temperature.

3. Different uses

Pickling plate is a developing steel varieties, the current market demand is mainly concentrated in the automobile industry, compressor industry, machinery manufacturing industry, zero processing industry, fan industry, motorcycle industry, steel furniture, hardware accessories, electric cabinet shelves and various shapes of stamping parts. With the progress of technology, hot rolled pickling plate has been involved in household appliances, containers, electrical control cabinet and other industries, in which the use of hot rolled pickling plate instead of cold plate in some industries developed quickly.
Cold plate surface quality, high dimensional accuracy, coupled with annealing treatment, its mechanical and technological properties are better than hot rolled thin steel plate, in many fields, especially in the field of household appliances manufacturing, has gradually replaced the hot rolled thin steel plate.

According to its different uses, hot rolled plate can be divided into: cold forming steel, structural steel, automotive structural steel, corrosion resistant structure steel, mechanical structure steel, welding cylinder and pressure vessel steel, pipeline steel and so on.
