Q:Stainless steel strap easy to scrape, how to deal with?
On the local case or watch strap deep scratches, repair before the need to do local processing, look at the location, such as the shell side case, there may even use the fine small file, more is the use of stone, then under the magnifying glass, carefully remove deep scratches and boring flat, deep scratches in the first, to focus on the local stone grind. This needs to be under a magnifying glass, the purpose is to scratch evenly polished, when basic scratches are going to grind, choose suitable size to sandpaper, grinding along the original sand drawing lines, so the lines are usually on the dial radially, and this is a carefully, to a little, the effect will be good to rub out the realistic. It is recommended that the sand paper be used in jewelry industry, preferably imported, such as German warrior brand water sandpaper.
Q:Which stainless steel belt has better elasticity?
In stainless steel strips, SUS301 has the best elasticity, and is used for springs, springs, or EH, or spring.SUS301 is the highest hardness, can be HV590 degrees, is less than SUS304. If you want to use the materials required materials SUS301 HV480.
Q:Stainless steel pan with magnetic or good without magnetic stainless steel pot?
Stainless steel pot without magnetic is good.In fact, stainless steel is magnetic, and the best stainless steel is austenitic stainless steel, and its magnetic is already weak, and basically no magnetic.
Q:Is there any magnetism in stainless steel?
Iron and steel are different in terms of carbon content. An iron carbon alloy with a carbon content of less than 2% is a steel, and a carbon content of more than 2% is called iron. Steel is widely used because of its toughness, elasticity and rigidity. Life is exposed to steel, but people call different. For stainless steel, whether or not the magnet is sucked on or not, as long as the quality standards are met, it is stainless steel. Therefore, from the perspective of metallurgy said, no rust said. The main element of stainless steel corrosion resistance is chromium. If the content of chromium is above 10.5%, the steel will not rust. When smelting, the alloy elements added are different, so there is a difference between the magnet and the suction. Stainless steel is usually divided according to the structure of the organization, can be divided into austenite, ferrite, martensite and other major categories.
Q:The difference between stainless steel and cold rolled steel strip
It: cold rolled steel strength is very high, but the toughness and weldability is poor, hard, crisp, bright surface
Q:How can 304 stainless steel and 201 stainless steel be distinguished by magnet?
After pickling of stainless steel, surface color silver finish: chromium nickel stainless steel color white jade is white; chromium stainless steel slightly weak light Ze; CrMnN Stainless steel and chromium nickel stainless steel similar color is slightly lighter. The surface color: stainless steel pickling chrome nickel steel is brown and white, brown and black chromium, chromium manganese nitrogen is black (the three color refers to the oxidation of the heavier color). Cold rolled unannealed chromium nickel stainless steel, silver reflective surface.
Q:Do you have stainless steel with magnetic?
The chromium content of ferritic stainless steel (400 Series) is 15%~30%, and has the structure of body centered cubic crystal. This kind of steel does not contain nickel, sometimes also contain a small amount of Mo, Ti, Nb and other elements, this kind of steel has high heat conductivity, low expansion coefficient, good oxidation resistance and anti stress excellent characteristics of stress corrosion, used formanufacturingthecorrosionresistanceofthe atmosphere, water vapor, waterandoxidizing parts.
Q:Stainless steel narrow band, what are the spare rolls and side bands?
Narrowband: General slitting machine, can only be divided into 12 ~ 15 mm width, and then down, it is not accurate, and therefore narrower band, you must use a special separator, so the price of narrowband will be higher.
Q:Why does stainless steels 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.In general, austenitic stainless steel and austenitic stainless steel (non-magnetic magnet can not suck), there are other ferrite stainless steel, with the ferromagnetic (magnets attract). But they can not just use a stainless steel magnetic discrimination. For the stainless steel tube, no magnet up or not, as long as the quality standards are stainless steel.
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.
