Product Description:

1.Structure of Stainless Steel Coil

Stainless steel coil is a production which not easy rust, acid resistance and corrosion resistance, Stainless steel coil is a new kind of Austenite stainless steel by used Mn, N replace Ni. so it is widely used in light industry, heavy industry, daily necessities and the decoration industry. Stainless steel coil has good corrosion resistance and hot / cold processing performance, instead of stainless steel products for used in the not high of corrosive environment, such as indoor, inland city outdoor etc.

2.Main Features of the Stainless steel coil

Q:Classification and application of stainless steel?
Stainless steel is usually divided into 1 parts according to the matrix: ferritic stainless steel. Chromium 12% ~ 30%. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and the resistance to chloride stress corrosion is better than other kinds of stainless steel. 2 austenitic stainless steel. Chromium more than 18%, but also contains about 8% of nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good comprehensive performance, corrosion resistant variety of media. 3 austenite ferrite duplex stainless steel. It has the advantage of austenite and ferritic stainless steel and has superplasticity. 4 martensitic stainless steel. High strength, but poor plasticity and weldability.
Q:Can 304 stainless steel be electroplated?
In order to plating the coating with good bonding ability, we must solve the problem of this layer of film. That is to say, before the new film is formed, the coating is plated, the problem is solved, and this is the pre plating process. The pre plating is preferably performed in two steps, namely activation and pre plating. Activation is usually performed by anodic or cathodic treatment in sulfuric acid solution, removing the surface passivation film, and then pre plating in the pre plating bath. Pre plating solution usually contains more than 200g/L more than 100mL/L of nickel chloride and hydrochloric acid, because of containing high concentrations of hydrochloric acid solution, pH is very low, not only have a strong activation effect on the substrate surface, will produce a large amount of hydrogen in the pre plating process, the new ecological has strong effect of hydrogen reduction on the substrate surface, a layer of nickel it is coated on the surface of the nickel layer activation, cut off the air, the surface will not generate passivation film. Pre plating and then plating other coating, bonding force naturally high.
Q:Is stainless steel and stainless steel coating the same thing?
Stainless steel coatings are electroplated by means of protective coatings that are indicated on the workpiece! The material on this layer is made of stainless steel. So the two concepts are different
Q:Why does stainless steel carry magnetism?
Often use magnets to determine whether stainless steel magnet attracts people, that is the stainless steel, the stainless steel is impossible. It seems that the people of stainless steel as well as understanding the misunderstanding. In fact this is just the difference between austenitic stainless steel and other stainless steel has no magnetism.
Q:Stainless steel tableware is fading, what's the matter?
Is 304 stainless steel, stainless steel may be the quality is not good, the market often take 201 stainless steel shoddy, the quality can not be guaranteed
Q:What is the difference between stainless steel taps and ordinary taps?.
The quality of stainless steel taps is different from that of ordinary taps, and special taps usually have coatings (such as TiN, etc.).
Q:How to distinguish between steel and stainless steel
In daily life, we have more contact with austenitic stainless steel (some people called nickel stainless steel) and martensitic stainless steel (some people call it "stainless iron", but not scientific, easy to misunderstand, should avoid) two categories. Austenitic stainless steel is typically 0Cr18Ni9, i.e. "304" and "1Cr18Ni9Ti". Martensitic stainless steel for manufacturing stainless steel cutlery, brands include 2Cr13, 3Cr13, 6Cr13, 7Cr17 etc.. Due to differences in the two kinds of stainless steel components, the inner microstructure of the metal is not the same.
Q:Can ordinary carbon steel be welded to stainless steel?
Can be welded, stainless steel and carbon steel welding belong to the welding of heterogeneous steel, austenitic stainless steel electrodes are generally used A302.
Q:Can stainless steel be hardened?
Between 350 to 450 DEG C after nitriding of austenitic stainless steel card surface strengthening by low pressure plasma glow discharge technology, under the pressure of 100 ~ 150KPa, 60 ~ 100 minutes to get a thickness of 10 to about 30 um high nitrogen austenitic hardness of supersaturated solid solution strengthening layer. The layer structure is analyzed to show that X ray diffraction, electron probe and auger spectrometer, the processing temperature is lower than 450 DEG C, the layer is the single nitrogen supersaturated solid solution layer of austenite, hardness reaches IOOOHV, compared with the original material, the wear resistance increases 2 ~ 3 times.
Q:What's the color difference between colored stainless steel screen and other products?
Color stainless steel screen is art, and other products are not the same, and its requirements for the process is very high, for now, the stainless steel screen of the degree of mechanization is not high, are handmade.
