Q:The difference between stainless steel and cold rolled steel strip
Stainless steel: the surface appearance and the possibility of the use of various good corrosion resistance than ordinary steel, durable good corrosion resistance and high strength, so the possibility of using large sheet of high temperature oxidation resistant and high strength, it can fire resistant temperature processing, plastic processing is easy because without surface treatment, so simple, maintenance is simple and clean, bright and clean a high degree of good welding performance.
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:Do you have stainless steel with magnetic?
Ferritic stainless steel is generally magnetic, austenitic stainless steel is generally non-magnetic. So we can't generalize.
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: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?
Volume: due to the use of the problem, customers may come to buy materials, do not buy the entire volume of material, but cut the plate for sale, the remaining less than a roll of materialMaterials, called rolls, are lower in price than normal materials.
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: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
