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?
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:What is the difference between stainless steel coil and stainless steel plate?
Stainless steel (Stainless Steel) is referred to as the stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; while the resistance to chemical corrosion (acid, alkali and salt chemical etching) corrosion of steel called acid resistant steel.
Q:Stainless steel pan with magnetic or good without magnetic stainless steel pot?
Without magnetic material if it is of course good 316304 of the material, if it is 201202 or easy to rust, the magnetic material is 443 than 304, this is due to their corrosion resistance, high heat conduction rate of 443, in the province of gas when cooking, can also be used with magnetic pot do the electromagnetic oven, 443 material pot is cheaper than 304, considering the magnetic well
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: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:Stainless steel narrow band, what are the spare rolls and side bands?
Sideband: roll out of the steel plant, has a certain width, when customers order the specified width, need to do a movement, to meet customer demand, but the width of the collocation, not satisfactory, will the remaining material (not in a material), such as roll material is 1185mm wide, to the customer is 60mm wide, the rest of the material is, the price is the lowest.
Q:Is the stainless steel condiment bottle good for rotating or for all holes?
Many stainless steel grades, different properties, and in the course of its development has gradually formed several categories. According to the structure of the organization, it is divided into four categories: martensitic stainless steel (including precipitation hardening stainless steel), ferritic stainless steel, austenitic stainless steel and austenitic ferrite duplex stainless steel;
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: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.
