 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:420 stainless steel, there is no good 304
420 and 304 is not the same type of stainless steel, is 420 stainless iron, nickel containing little, 420 series stainless steel cutter belongs to the material processing of finished products and then quenching hardness is high, the 304 is rust resistant stainless steel material, widely used, the price is slightly more expensive than the 420, at about 20 yuan a kilogram.
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:What glue does the board or the stainless steel stick to?
Epoxy resin (adhesive) generally refers to the epoxy resin as the main body of the adhesive, epoxy resin should generally include epoxy curing agent.
Q:What's the difference between 304 stainless steel and 314?
304 stainless steel is a universal stainless steel material: 314 stainless steel; high temperature oxidation resistance and strong mechanical properties; high heat resistant stainless steel, and 314 austenitic stainless steel, high temperature oxidation resistance and creep resistance. 314 stainless steel used in furnace tube difference
Q:What kind of welding rod is used for 310S stainless steel?
A132 welding electrodes are used to weld important corrosion resistant, Ti stabilized 0Cr19Ni10Ti stainless steels.A137 is an Cr19Ni10Nb stainless steel electrode with an alkaline coating and a low carbon content containing Nb stabilizer. It is used for welding important corrosion resistant Ti stabilized stainless steel 0Cr19Ni11Ti.310S stainless steel is austenitic chromium nickel stainless steel, with good oxidation resistance, corrosion resistance, acid and alkali resistance, high temperature resistance. Mainly used in petroleum, electronics, chemical, pharmaceutical, textile, food, machinery, construction, nuclear power, aerospace, military and other industries.
Q:How high is the temperature of 2520 stainless steel?
For Ni (Ni), chromium (Cr) content is high, with good oxidation resistance, corrosion resistance, acid and alkali resistance, high temperature performance, high temperature resistant steel dedicated to the manufacture of electric furnace tube and so on, increase the amount of carbon austenitic stainless steel, due to the solid solution strengthening effect to the strength improved, chemical composition characteristics of austenitic stainless steel is chrome, nickel based addition of molybdenum and tungsten, niobium and titanium elements, as its face centered cubic structure, and strength and high creep strength at high temperature.
Q:What is stainless steel plate wire?
A filament is a unit of length.In mathematics 10 decimillimeter centimillimeter decimillimeter =1 mm, 10 =1
Q:What's the drill for stainless steel?
Stainless steel is characterized by high toughness, easy to stick the knife, so requires higher hardness of the drill bit, surface finish is better, the drill tip angle than the ordinary drill (130--135 degrees). At the same time, cooling should be sufficient
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?
A continuous rolling mill is put in billions of dollars, but this is the rolling mill, and there are many gold furnaces. But the technical content of carbon steel with stainless steel is different, our country in more than 10 years ago the ability of continuous rolling of stainless steel is not high, equipment are imported, the stainless steel mill is dominated by 1219-1300, but also the development of national wide stainless steel 1500-2050, but the price is expensive at least thousands of dollars a ton, after all put the equipment to recover the cost, and the number of business orders is not much, it is difficult to find a spot on the market. Carbon steel countries have developed for many years, technology and equipment are mature, so the market has 1250 as production standards.
Q:304 stainless steel plate 1*1219*C what do you mean?
Roll thickness 1 mm, width 1219 mm, length is unlimited (depending on volume weight). 304 stainless steel is a kind of the most commonly used, law-abiding.
