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 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: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: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: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:Why does the stainless steel after processing have magnetism?
In addition, 304 stainless steel after cold processing, the structure of the structure will also change to martensite, and the greater the deformation degree of cold work, the more martensitic transformation, the greater the magnetic properties of steel. The stable austenite structure can be recovered by high temperature solution treatment so as to eliminate magnetism.
Q:301 stainless steel belt and 304 stainless steel belt, which quality is good?
No absolute, which quality is good, the key depends on what kind of product is suitable. Under normal circumstances, the requirements of hardness, elasticity, as elastic components, structural parts of the 301 materials used more, can also achieve a higher hardness of about HV600. Product positioning higher, 304 materials can be appropriately selected, the highest hardness can reach about HV500.
Q:Is the stainless steel condiment bottle good for rotating or for all holes?
Generally divided into martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel and precipitation hardening stainless steel, etc., or divided into chromium, stainless steel and nickel stainless steel two categories.
Q:How can 304 stainless steel and 201 stainless steel be distinguished by magnet?
Magnets can basically distinguish between the two types of stainless steel. Because 201 stainless steel (chromium, stainless steel) in any state can be attracted by magnets; 304 stainless steel (chromium nickel stainless steel) in the annealing state is generally non-magnetic, and after cold processing, some will be magnetic. However, the manganese steel with high manganese content is non-magnetic; the magnetic properties of chromium, nickel and nitrogen stainless steel are more complex: some are non-magnetic, some are magnetic, some are without magnetism and the surface is magnetic. Therefore, although the basic difference between magnet chromium and chromium nickel stainless steel, but can not distinguish between some special properties, but not distinguish the concrete steel.
