Hot Rolled Stainless Steel Coil 304 Annealing and Pickling No.1 Finish

Stainless steel is a production which not easy rust,acid resistance and corrosion resistance,so it is widely

used in light industry,heavy industry,daily necessities and the decoration industry.

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.

Q:What is the hardness of stainless steel band 3/4?: Hello, 3/4H stainless steel has too many materials, I don't know what kind of material you are talking about 301 and 304 are different. 3013/4H harder. 304 soft. And 201430, etc.... All different

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: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:301 stainless steel belt and 304 stainless steel belt, which quality is good?: 304 good soft hard 301 good 304 some hardness is not to Yi Teng metal

Q:Which stainless steel belt has better elasticity?: 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: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 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?: If you go to the molten steel and high chromium nickel austenitic steel, tempered magnet is not stainless steel. If the molten steel in the main alloy elements is chromium, iron and carbon and a small amount of nickel (or without nickel), tempered steel is a magnet on the stainless steel, also called ferritic stainless steel martensitic stainless steel or austenitic stainless steel. In addition to the magnet is not on, ferrite, martensite stainless steel are magnetic. The nickel element in the reserves in the world is very few, the price is more expensive, therefore, high nickel content in stainless steel on the market price is higher, and the magnet suction is not at present because of austenitic stainless steel for stainless steel in the proportion is still great, so that people have a misconception of all stainless steel are non-magnetic.

Q:What type of stainless steel is magnetic stainless steel?: Model with magnetic stainless steel: martensite or ferrite: such as 430, 420, 410 and so on, is magnetic.
