Common steel delivery status
1) Cold rolling
u The advantages of cold rolling are good dimensional accuracy
,surface quality ,low surface roughness ,high mechanical
properties.
u The steel surface of the cold-rolled (forging) state delivery has
oxide skin coverage and there is a great internal stress, so likely
to suffer corrosion or rust,.Therefore , its packaging and storage
have relatively strict standards
2) Hot rolling
u Hot rolling (forging) steel plate’s termination of a temperature is 800-900 degrees Celsius, then
generally natural air cooling.
u Hot-rolled steel state because of the surface is covered with a
layer of oxide scale,so having some corrosion resistance, less
stringent storage and transport requirements, unlike steel
cold-rolled state delivery.
Brief introductions of different processing surfaces :
| Surface finish | Characteristics and application |
| No.2B | The surface brightness and flatness of no2B is better than no2D.
then through a special surface treatment to improve its mechanical
properties,No2B could nearly satisfy comprehensive uses. |
| 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 buildings ornaments
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. |
| NO.1 | Hot rolled, annealing, pickling. Usually used to cold rolled
material, pot for industry, device for the chemical industry and so
on. |
