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: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?
1/2 hardness range: HV250 degrees to HV2903/4 hardness range: HV310 to HV370(HV:, Vivtorinox hardness)
Q:Why does stainless steels 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: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: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:Does the 301 stainless steel band contain magnetism?
301 austenitic stainless steel, with slight magnetism. The austenite belongs to the BCC crystal, generated in the above the Curie point, Curie point magnetic transition point, so the austenite is not magnetic, but specific to the austenitic stainless steel, because of a great relationship and Cr stainless steel corrosion resistance elements, Cr ferrite forming elements, so that the austenitic stainless steel will have at least 5% or so the ferrite, so it has slight magnetic magnet can be found out.
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:301 stainless steel belt and 304 stainless steel belt, which quality is good?
You can be responsible to tell you, 304 to better stainless steel, the amount of nickel will be on the 304 to more than 301
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.SUS301 is the highest hardness, can be HV590 degrees, is less than SUS304. If you want to use the materials required materials SUS301 HV480.
