 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 are the specifications of stainless steel plates? Are they the same width?
Different specifications, width is not the same, there are 1.22 meters, 1 meters, etc., length, width, thickness are different.
Q:What does "80 wire" stainless steel plate mean? How much more expensive than the average stainless steel plate?
It's 0.08mm stainless steel!! It's so thin. It's expensive. A kilo is at least 10 yuan!!
Q:What's the difference between cold rolled plate and stainless steel?
Cold rolled plate is the difference between "hot rolled plate", that is, the temperature of the hot-rolled steel plate is different, the strength is different, the cost is slightly different. The composition and elements of the two parts are basically the same
Q:How about stainless steel grades?
304 - that is, 18/8 stainless steel. GB is 0Cr18Ni9. 309 - better temperature resistance than 304. 316 - after 304, second of the most widely used steel grades are used mainly in the food, pharmaceutical and pharmaceutical industries, and molybdenum is added to obtain a special corrosion resistant structure. Because of its better resistance to chloride corrosion than 304, it is also used as "ship steel". SS316 is usually used in nuclear fuel recovery devices. Grade 18/10 stainless steel usually meets this application level. [
Q:What glue does the board or the stainless steel stick to?
In addition to the bonding (ordinary bonding and bonding structure), epoxy resin can be used for casting, sealing, sealing, sealing, anti-corrosion, insulation, conductive, fixed, reinforcement, repair etc., are widely used in aviation, aerospace, ships, railway, machinery, chemical industry, light industry, water conservancy, weapons, electronic and electrical, construction, medical, sports goods, arts and crafts, daily life and other fields.
Q:Is stainless steel plate permitted to contact galvanized material?
If your product will come into contact with electrolyte or water, the stainless steel bolt will produce a galvanic cell with carbon steel to accelerate the corrosion speed of both sides. At this point, corrosion is called electrochemical corrosion, and the reaction rate is faster.
Q:What kind of welding rod is used for 310S stainless steel?
What kind of welding rod is used for 310S stainless steel?:310S stainless steel should be welded with ER-310 wire or A132 and 137 electrodes.
Q:Is Baoding mirror stainless steel plate mirror on both sides?
Yes, mirror stainless steel plate is divided into: single universal grinding 8K stainless steel plate, stainless steel plate, 8K universal grinding double-sided single-sided grinding 8K stainless steel plate, double-sided grinding of 8K stainless steel plate, manufacturers generally can be customized according to your requirements, the price is not the same.
Q:What does 8K stainless steel mean?
The literal definition of 8K: the composition of the alloy corrosion resistance of stainless steel white just depends on its (Cr, Ni, Ti, Si, Mn) and internal organizational structure, which play a decisive role is chromium, it can form a passivation film on the surface of the steel, the metal isolation does not produce oxidation and enhance the ability of corrosion resistance of steel plate. In 8K, the "8" refers to the proportion of ingredients containing alloy (304 stainless steel mainly refers to the content of Ni element), "K" refers to after polishing after the reflectance grade (grade K grade mirror). 8K mirror, that is, chrome nickel alloy steel reflects the mirror level.
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.
