 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:What's the difference between 304 stainless steel and 301 stainless steel?
301 GB code 1Cr17Ni7; 304 GB mark 0Cr18Ni9
Q:What's the difference between stainless steel 8K and BA?. How to distinguish from the surface of materials?
The 304430 BA of stainless steel can achieve the effect of 6K or 8K. Is the most direct Kanban lines then some words to be processed is certainly not 8K, BA is 8K achieve brightness over direct annealing processing completely invisible plate lines in acid corrosion in the grinding process has damage the surface of the protective layer.
Q:Welding defects analysis of 1.5mm stainless steel plate
OveripThe partial fusion of molten metal flowing to the base metal other than the weld.Reason: improper selection of welding parametersGroove cleaning is not clean, the arc heat loss on the oxide skin, so that the parent material is not melting.Hazard: the surface is the fact is often below the incomplete fusion, lack of penetration;Weld geometry changes, stress concentration, pipe welding tubular medium circulation reducing interface meter.
Q:Several processing techniques of colored stainless steel
Sand blasting, sand blasting can be plated color, but the color of the plating and ordinary plating color difference exists, mainly due to sand blasting particles for emery. The color stainless steel sand blasting plate is made of zirconium beads through the mechanical equipment in the stainless steel plate surface, so that the surface of the board presents small beads, grainy sand surface, forming a unique decorative effect. Uses: mainly used in architectural decoration, elevator decoration, industrial decoration, facilities, decoration and other stainless steel products.
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:Stainless steel drawing plate, polishing plate, mirror panels of the three differences?
Stainless steel wire drawing refers to: stainless steel wire drawing is stainless steel surface like filamentous texture, this is only a stainless steel processing technology. The surface is Matt, and carefully look at the above there is a trace of texture, but can not touch it.
Q:304 how can the water stain on the surface of stainless steel plate be formed?
This is mainly the unclean environment and surface protection measures are not done well, stainless steel plate surface water stains even if frosted, not necessarily can be worn off
Q:What's the difference between 201 and 204 stainless steel plates? Thank you
The price is different: 01 cheaper, 04 expensive. Toughness is different: 01 hardness, 04 toughness.
Q:304 stainless steel plate 1*1219*C what do you mean?
304 stainless steel is a universal stainless steel material, antirust performance than the 200 series of stainless steel material stronger. High temperature resistance is also good, can be as high as 1000-1200 degrees. 304 stainless steel has excellent stainless steel corrosion resistance and better intergranular corrosion resistance. The oxidizing acid, in the experiments: the concentration of more than 65% of boiling temperature following nitrate, 304 stainless steel has high corrosion resistance. Alkaline solution and most organic acids and inorganic acids also have good corrosion resistance.
Q:Stainless steel plate laser cutting how to charge?
It's plasma cutting... In fact, if the process is not required, you can buy a hand grinder with cutting pieces.
