0.025mm~4mm 201 304 316 Stainless Steel Coil Metal Strip Steel
Sheet
Stainless steel coil production process involves several steps.
First, the raw materials, like stainless steel scrap or ingots, are
melted in a furnace. Once melted, the molten steel is poured into a
continuous caster, which produces a long, semi-finished slab.
The slab is then heated and rolled in a hot rolling mill to reduce
its thickness and increase its length. This process is repeated
multiple times, gradually reducing the thickness of the slab and
achieving the desired dimensions.
After hot rolling, the coil is annealed to relieve internal
stresses and improve its mechanical properties. Annealing involves
heating the coil to a specific temperature and then cooling it
slowly.
Next, the coil is pickled to remove any scale or impurities on the
surface. Pickling is typically done by immersing the coil in an
acid bath or applying an acid solution.
Once pickled, the coil is cold rolled to further reduce its
thickness and improve its surface finish. Cold rolling involves
passing the coil through a series of rollers at room temperature.
Finally, the coil is trimmed, inspected for quality, and then
packaged for shipment. It can be further processed into various
stainless steel products, such as sheets, strips, or tubes,
depending on the customer's requirements
Surface finish | Characteristics and application |
NO.2B | ensive uses. |
NO.1 | The surface is finished by heat treatment and pickling or processes
corresponding there to after hot rolling. |
NO.4 | Polished with abrasive belt of grit #150-#180,have better
brightness with discontinuous coarse stria,but thinner than No3,
are used as bathtub buildings inner and external ornaments
electrical appliances kitchen utensils and food processing
equipment etc. |
HL | Polished with abrasive belt of grit #150#320 on the NO.4 finish and
has continuous streaks,mainly used as buildingsornaments
elevators,door of building,frontal plate etc. |
BA | Cold rolled, bright annealed and skin-passed, the product have
excellent brightness and good reflexivity like mirror,kitchen
apparatus,ornament etc. |
8K | The product have excellent brightness and prefer reflexivity can to
be the mirror. |
