 Stainless steel sheet surface finish characteristics



Surface finish

Characteristics and application


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.


Polished with abrasive belt of grit#100-#200, have better brightness with discontinuous coarse stria, used as inner and external ornaments for building, electrical appliances and kitchen utensils etc.


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.


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.


Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror, kitchen apparatus, ornament etc.


The product have excellent brightness and prefer reflexivity can to be the mirror.

Q:304 stainless steel plate surface quality inspection method which has several?
304 stainless steel surface quality of pickling process mainly depends on the heat treatment, surface oxidation Pihou formation if heat treatment before a process, or organization is not uniform, with acid does not improve the surface smoothness and uniformity. Therefore, attention should be paid to heat treatment or surface cleaning prior to heat treatment.
Q:How do you put the mirror panel on the stainless steel panel?
Stainless steel passivation treatment (passivation, of, stainless, steel)Our company specializes in stainless steel surface treatment, providing all types of stainless steel pickling and passivation processing business.The company adopts advanced passivation process and self matching passivation reagent, according to your passivation requirements for the preparation of products, targeted, fully guarantee your passivation process all the requirements.We can not only become your processing partner, but also willing to become a partner with you.
Q:Advantages and disadvantages of stainless steel
Stainless steel is the main advantage of corrosion resistance or high temperature, general acid resistant medium, as well as heat resistance, high temperature oxidation (heat resistant skin) of high temperature stainless steel.
Q:What's the difference between 304 stainless steel and 314?
All belong to austenitic stainless steel, 304 is the most common, and 314 of the alloy content is higher than 304, better performance, especially high pressure heat resistance.
Q:What does stainless steel plate mean?
The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and the internal structure of the alloy, and the main role is chromium. Chromium has high chemical stability, can form a passive film on the steel surface, so that the metal is isolated from the outside, protect the steel plate from oxidation and increase the corrosion resistance of the steel plate. When the passive film is destroyed, the corrosion resistance will decrease.
Q:What is the stainless steel grid board? What areas of stainless steel mesh panels are used in?
Stainless steel grid plate, also called stainless steel steel grid plate, the two are the same product, just name different
Q:430 stainless steel plate maximum temperature tolerance is how many degrees?
All the properties of 430 stainless steel with 430 stainless steel, with good corrosion resistance and better thermal conductivity than austenitic steels, thermal expansion coefficient smaller than the austenitic thermal fatigue, adding stabilizing elements of titanium, parts of the mechanical properties of the welded seam, mainly used for building decoration, household appliances, fuel burner parts, home appliance parts.
Q:What is the width of the carbon steel coil and the width of the stainless steel coil, one is 1250, and the other is 1219?
Domestic stainless steel rolling mill is generally 1219, but the design standard is 1300, so there will be flash board 1250, that is not the standard board, belonging to the flash, waste materials, many products manufacturers are also in 1219 as a reference size, product development, if the plate width will be wasted, a lot of scrap production the process, so the business order is generally around 1219 stainless steel coil.
Q:What is the process of stainless steel mirror panel? What's the difference between them and stainless steel sand blasting plates?
The 8K board, also called mirror panel, is polished on the surface of stainless steel by grinding fluid through polishing equipment, so that the surface of the plate is as clear as the mirror. Uses: mainly used in architectural decoration, elevator decoration, industrial decoration, facilities, decoration and other stainless steel products.
Q:904L stainless steel plate generally used in what industry is more?
Super austenitic stainless steel (904L stainless steel) is a highly alloyed austenitic stainless steel carbon content is very low, in dilute sulphuric acid has good corrosion resistance for corrosion in harsh environmental conditions and design.
