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: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: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:Does the 301 stainless steel band contain magnetism?
301 is our country's 1Cr17Ni7, belongs to 18-8 type austenitic stainless steel varieties, itself should be no magnetism, there is opportunity processing and pressure processing may produce processing magnetism, but after the heat treatment, magnetism will disappear
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 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: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: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:What type of stainless steel is magnetic stainless steel?
1, 420- type "cutting class" martensitic steel, similar to Brandt's first high chromium stainless steel this. Also used in surgical knives, which can be made very bright.2 model 430- ferritic stainless steel for decorative purposes, such as automotive accessories. Good formability, but poor temperature resistance and corrosion resistance.3, 440- type high strength cutting tool steel, carbon is slightly higher, after appropriate heat treatment to obtain a higher yield strength and hardness can reach 58HRC, which belongs to the most hard stainless steel column. The most common example is razor blades".
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.
