- Q:How can 304 stainless steel and 201 stainless steel be distinguished by magnet?
- 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 high manganese steel, magnetic for ordinary steel or low-alloy steel.
- Q:What is the hardness of stainless steel band 3/4?
- 304 stainless steel is the United States materials and Testing Association (ASTM) named SUS 304 stainless steel brand abbreviation. 304 stainless steel, 1Cr18Ni9., is a widely used austenitic stainless steel.
- Q:Stainless steel strap easy to scrape, how to deal with?
- As the process of case surface, basically of two kinds: polishing and sand, or both, grinding watch case on the scratch, but also in accordance with the original process to do a large area of hair road wear, relatively easy to handle; but if there is hard scratch deep, will be trouble some, because both polishing and sand drawing techniques, are not enough to remove the scratches.
- Q:301 stainless steel belt and 304 stainless steel belt, which quality is good?
- You can be responsible to tell you, 304 to better stainless steel, the amount of nickel will be on the 304 to more than 301
- 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: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:What are the main stainless steel belt used in the industry and products?
- This is the fastest growing area of stainless steel applications. The use of high strength stainless steel car body structure can greatly reduce the weight of the car, and enhance the strength of the body structure, using stainless steel as vehicle panels and decorative parts, can reduce maintenance costs.The problem of water pollution during storage and transportation has been paid more and more attention. A great deal of practice has proved that stainless steel is the best choice for water preparation, storage, transportation, purification, regeneration, desalination and other water industry. The advantages are: corrosion resistance, earthquake resistance, water saving, sanitation (no rust and copper green), light weight (reduced 1/3), Shao Weixiu, long life (40 years service), life cycle cost (LCC) is low, Recyclable using green materials.
- 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: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.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's the difference between stainless steel coil and stainless steel plate?
- One is a coil and the other is a strip.
