Q:Stainless steel without fingerprint processing how to get?
And processing, such as bending or stamping and other general processing can meet the requirements. The utility model improves the influence of fingerprints or oil pollution in the use of stainless steel products, and solves the difficult problem that the surface is easy to stick dirt and is difficult to clean. Meanwhile, the utility model avoids the defects of stainless steel surface damage, blackening or losing luster caused by the treatment of fingerprints or oil pollution by common chemical solvents. This is a new type of stainless steel surface processing technology, stainless steel material is not limited: such as 201#, 202#, 301#, 304#, 430#, 443# and so on can be processed!
Q:What does "80 wire" stainless steel plate mean? How much more expensive than the average stainless steel plate?
80 silk is 0.8MM thick stainless steel plate, the price is almost the same
Q:What's the difference between cold rolling and hot rolling of stainless steel plate?
Cold rolling and hot rolling are different processes, and cold rolling is usually made by longitudinal rolling. Cold rolling process usually includes preparation of raw materials, pickling, rolling, degreasing, annealing (heat treatment), finishing and so on. Cold rolling takes hot rolling product as raw material, and the raw material should be removed before cold rolling so as to ensure the surface cleanness of cold rolling products.
Q:What is the difference between stainless steel coil or stainless steel plate?
Stainless steel (Stainless Steel) is the abbreviation of stainless acid resistant steel, corrosion resistance of air, steam, water and other corrosive media or stainless steel grades, known as stainless steel;
Q:What is the difference between stainless steel 304 and stainless steel 202?
Is the steel of the oxide layer was removed, put a drop of water, rub rub after copper sulfate, such as discoloration, usually stainless steel; such as purple red: nonmagnetic as high manganese steel, magnetic for ordinary steel or low-alloy steel.
Q:Several processing techniques of colored stainless steel
1, water plating (mainly black, note 304 plating water plating, color instability, slightly blue, mirror surface is particularly obvious, treatment method for high temperature without fingerprint processing, but the surface will be brown)2, electroplating - PVD vacuum plasma plating (can be plated sapphire blue, black, coffee, seven color, zirconium, gold, bronze, bronze, rose, champagne, golden, light green)
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 do stainless steel 304 industrial surfaces refer to?
The industrial surface is the ordinary pickling surface, which is treated by the last pickling process. Is the kind of white surface that you see at ordinary times. The bright surface of life is the surface of which is further polished or annealed.
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 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.
