Small household appliances in the supermarket area will always see some customers to buy stainless steel kitchen utensils, holding a magnet to suck in the stainless steel containers to smoke. Asked him, why use the magnet suction. He said that the magnet is sucked on the stainless iron, not on the suction of stainless steel, good stainless steel no magnetic. In fact, this is not accurate.Stainless steel wire suppliers
Stainless steel to see why the magnetic iron and steel is the amount of carbon content to distinguish. Carbon content of 2% or less of iron-carbon alloy is steel, carbon content of 2% or more is called iron. For stainless steel, regardless of whether the magnet sucked or not, as long as meet the quality standards, are stainless steel. The main element of corrosion-resistant stainless steel is chromium. Steel with a chromium content of 10.5% or more is less likely to rust. Smelting alloy elements added to the different, there will be a magnet on the suction and not on the difference between the suction.ASTM A276 303 stainless steel coil
Stainless steel generally by organizational structure can be divided into austenite, ferrite, martensite and other broad categories. If you add to the molten steel with a small proportion of nickel (or nickel), made of steel is the magnet Sucked on the stainless steel, also known as ferritic stainless steel; martensitic stainless steel is the main alloying elements of chromium, iron and carbon. In addition to austenitic stainless steel magnet is not on the suction, the ferrite, martensitic stainless steel has a magnetic.stainless steel tube pipe made in China
According to the content points there are two kinds of stainless steel is not on the magnet suction, a high nickel content of stainless steel magnets do not smoke, but because of this element rare high prices. There is also a high manganese content of nickel or nickel-free stainless steel. This stainless steel market price higher than nickel-containing stainless steel per ton lower than 1,000 yuan. So the stainless steel with magnetic not judge its good or bad standard. Usually 304 stainless steel tube is austenitic stainless steel, non-magnetic, but after some bending kink and so will change with weak magnetic, and 304 stainless steel which also contains manganese and nickel, the magnet does not suck, but magnetic.hollow steel section sizes
