Q:Stainless steel strap easy to scrape, how to deal with?
They use sandpaper to repair scratches watchcase watchband above, is not difficult, as long as careful steady hand could do; but for the surface polishing process, it must use the polishing machine, ordinary people can not do.
Q:Which material is better, stainless steel or belt?
Summer is the best with a stainless steel belt, the belt in the summer after the sweat corrosion, there will be an unpleasant smell, easily broken; stainless steel material is relatively good, generally not bad, summer with sweat also nothing, no taste. I hope my answer will be helpful to you!
Q:What are the main stainless steel belt used in the industry and products?
It is one of the earliest fields of stainless steel application. In architectural decoration, at present, stainless steel is mainly used in high-rise building exterior wall, indoor and external column coating, handrails, floors, elevator panels, doors and windows, curtain walls and other interior decoration and components. After the surface treatment, coloring and coating of the stainless steel plate, the utility model solves the problems such as fingerprint easily appearing after touching, and further expands the application range of the stainless steel.In the home appliance industry, the large quantities of stainless steel are the inner cylinder of the automatic washing machine, the inner liner of the water heater, the inner and outer shell of the microwave oven and the lining of the refrigerator, and the ferritic stainless steel is adopted.
Q:Do you have stainless steel with magnetic?
Austenitic stainless steel is the stainless steel with austenite structure at normal temperature. When the steel containing Cr is about 18%, Ni, 8%~10% and C is about 0.1%, it has a stable austenite structure. Austenitic chromium nickel stainless steel includes the famous 18Cr-8Ni steel, and on this basis, increasing the content of Cr, Ni, and adding Mo, Cu, Si, Nb, Ti and other elements developed by the high Cr-Ni series steel.
Q:Is the stainless steel condiment bottle good for rotating or for all holes?
According to some characteristic elements of main chemical components in steel or steel in the classification, divided into chromium stainless steel, chromium nickel stainless steel, nickel chromium molybdenum stainless steel and low carbon steel, stainless steel, stainless steel and high molybdenum high purity; according to the characteristics and application of classification of steel, stainless steel, divided into nitric acid resistant stainless steel, high resistance to sulfuric acid pitting resistance to stress corrosion of stainless steel, stainless steel, stainless steel and other steel; according to the classification features, divided into low temperature stainless steel, non-magnetic stainless steel, stainless steel, stainless steel, free cutting superplasticity. At present, the commonly used classification methods are classified according to the characteristics of the steel structure, the chemical composition of steel and the combination of the two
Q:Why does the stainless steel after processing have magnetism?
In addition, 304 stainless steel after cold processing, the structure of the structure will also change to martensite, and the greater the deformation degree of cold work, the more martensitic transformation, the greater the magnetic properties of steel. The stable austenite structure can be recovered by high temperature solution treatment so as to eliminate magnetism.
Q:Why does stainless steels carry magnetism?
If you go to the molten steel and high chromium nickel austenitic steel, tempered magnet is not stainless steel. If the molten steel in the main alloy elements is chromium, iron and carbon and a small amount of nickel (or without nickel), tempered steel is a magnet on the stainless steel, also called ferritic stainless steel martensitic stainless steel or austenitic stainless steel. In addition to the magnet is not on, ferrite, martensite stainless steel are magnetic. The nickel element in the reserves in the world is very few, the price is more expensive, therefore, high nickel content in stainless steel on the market price is higher, and the magnet suction is not at present because of austenitic stainless steel for stainless steel in the proportion is still great, so that people have a misconception of all stainless steel are non-magnetic.
Q:What kind of plastic surface friction and wear in stainless steel belt is relatively small?
No solid modification of pure plastic on the surface of stainless steel wear is relatively small, such as polyethylene, PTFE and so on.
Q:What type of stainless steel is magnetic stainless steel?
There are many kinds of stainless steel. They can be divided into several groups according to the organizational structure at normal temperature:1, austenite type: such as 304, 321, 316, 310, etc is non-magnetic or weak magnetic.2. martensite or ferrite: such as 430, 420, 410 and so on, is magnetic.
Q:What is the hardness of stainless steel band 3/4?
Hello, 3/4H stainless steel has too many materials, I don't know what kind of material you are talking about 301 and 304 are different. 3013/4H harder. 304 soft. And 201430, etc.... All different
