Cold rolled steel coil made in China
Cold rolled steel coil, take hot rolled steel coil as raw material at room
temperature at a temperature below the recrystallization rolling from,
including board and roll, many domestic steel mills such as Baosteel,
Wuhan Iron and Steel, Anshan Iron and Steel, etc. can produce. Zhang
called for delivery in which a steel plate, also known as box board or
flat; length is long, rolled steel delivery is called, also known as coil.
Because the production process is not heated, so there often appears
pitting hot-rolled and iron oxide skin and other defects, surface quality, smooth finish.
Cold-rolled products and high dimensional accuracy, and product performance
and organization to meet some special requirements, such as electromagnetic properties, deep drawing properties.
Performance: The main use of low-carbon steel grades, requires a good cold bending and welding properties,
as well as some of the press performance.
