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:What kind of plastic surface friction and wear in stainless steel belt is relatively small?
Plastic itself than metal soft, so it is not bad stainless steel, and if the metal surface smoothness is low (micro Burr) will be broken plastic surface, in the contact surface, if there are hard particles will also be broken metal surface.
Q:Stainless steel strap easy to scrape, how to deal with?
On the local case or watch strap deep scratches, repair before the need to do local processing, look at the location, such as the shell side case, there may even use the fine small file, more is the use of stone, then under the magnifying glass, carefully remove deep scratches and boring flat, deep scratches in the first, to focus on the local stone grind. This needs to be under a magnifying glass, the purpose is to scratch evenly polished, when basic scratches are going to grind, choose suitable size to sandpaper, grinding along the original sand drawing lines, so the lines are usually on the dial radially, and this is a carefully, to a little, the effect will be good to rub out the realistic. It is recommended that the sand paper be used in jewelry industry, preferably imported, such as German warrior brand water sandpaper.
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: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: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: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.
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:What is the difference between stainless steel coil and stainless steel plate?
Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.
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.
