Chemical Composition (in weight %)
Stainless steel cold plate is fine steel, widely used in the aerospace, construction, home appliances, environmental protection, food, medical and automotive industries.Users of stainless steel cold plate surface quality requirements are very strict. Mastery of knowledge. So far, stainless steel cold plate surface quality of the main types of the following categories:
1,2 D surface
Surface Condition: uniform surface was matte like
Features: The matt surface after pickling or phosphorus removal. Available hair surface roller formation.
Such a surface suitable for machining deep drawability member need polishing process, but these parts after molding.
2,2 B surface
Surface Condition: smooth and straight surface than 2D
Features: 2D surface based on the heat-treated steel sheet after Dephosphorization polishing roll small reduction smoothness.
In addition to the extremely complex deep drawing, can be used for any purpose.
3, BA surface
Surface Condition: smooth, bright, reflective
Features: cold rolled bright annealing in a controlled atmosphere furnace. Usually used in the mixed atmosphere of hydrogen or a dry hydrogen with dry nitrogen to prevent oxidation phenomena in the annealing process. Also after the step of re-processing the common surface machining.
4,3 Road surface
Surface Condition: non-directional texture, not reflective.
FEATURES: need only to specify the level of polishing belt or surface roughness.
This surface apply to extend the product needs to be further processed occasions.
5,4 Road surface
Surface Condition: non-directional texture, reflective
Features: coarse abrasive kibble after, and then the size 120-150 number or finer abrasive fine grinding.
This material is widely used in restaurant equipment, kitchen equipment, shop fronts, dairy equipment.
Surface of 6,6 No.
Surface Condition: was matte-like direction texture
Features: the 4th surface of the steel plate the granularity abrasives and oil medium through Tampico brushing made.
Not required to apply to the building and decoration of the gloss.
7,7 Road surface
Surface Condition: smooth, highly reflective
Features: excellent foundation surface rub from. Surface wear scar can not be eliminated.
Buildings and decorations for applications that require high-gloss.
8,8 Road surface
The Surface Status: non-directional texture, high reflective, clear images
Characteristics: is the with gradual refinement abrasive and very fine colcothar for a large number of rub made.
The surface are widely used film platen, mirror.
9, TR surface
Surface Condition: changes in response to the size of the amount of material and cold
Features: annealing phosphorus removal or bright annealed steel plate enough cold hardening treatment.
10, HL surface
Surface Condition: was continuous grinding striated
Features: with appropriate particle size of the abrasive material to be polished, so that the surface was continuous grinding Auctions. (Zi Yan)
