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: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:Why does stainless steels carry magnetism?
In fact, there is also a stainless steel magnet can not afford, that is, high manganese or nitrogen and low nickel or nickel free stainless steel, chromium, manganese austenitic stainless steel, so it can not be based on whether or not to determine whether the magnetic stainless steel
Q:Why does the stainless steel after processing have magnetism?
The austenite is non-magnetic or weakly magnetic, and martensite or ferrite is magnetic, a tripod of stainless steel processing in processing time due to melting segregation or improper heat treatment, will cause a small amount of martensite Austenitic 304 stainless steel body or ferrite. In this way, 304 stainless steel will have a weak magnetic.
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:Stainless steel pan with magnetic or good without magnetic stainless steel pot?
Stainless steel pot without magnetic is good.In fact, stainless steel is magnetic, and the best stainless steel is austenitic stainless steel, and its magnetic is already weak, and basically no magnetic.
Q:What is the hardness of stainless steel band 3/4?
1/2 hardness range: HV250 degrees to HV2903/4 hardness range: HV310 to HV370(HV:, Vivtorinox hardness)
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:Which material is better, stainless steel or belt?
Speaking, of course, the material is stainless steel, stainless steel is not easy to change color, corrosion resistance, etc., and the cortex is not resistant to corrosion, and sometimes easy to fade. This should be based on their preferences, as well as personality and usual dress up, stainless steel for formal dress, such as shirts, suits, leather, suitable for casual wear
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.
