304 stainless steel plate processing need to pay attention to what? Below by the stone stainless steel to introduce you. The continuous casting billet of 304 stainless steel plate sent from the steel mill first enters the heating furnace, after repeated rolling by the blooming mill, it enters the finishing mill and cuts off the head of the plate. The finishing mill speed can be up to 20m/s, which should create the necessary conditions for hot processing. Stainless steel materials should be heat treated before leaving the factory.
304 stainless steel plate processing
304 stainless steel plate is difficult to process the main reason is high chromium and nickel content, so difficult to process, and processing also consumes a lot of tools. Therefore, in order to facilitate processing, a little more sulfur is added on the basis of 304 to form 303 stainless steel, which is easy to cut and suitable for lathe.
304 stainless steel plate according to the manufacturing method can be divided into hot rolling and cold rolling. According to the structural characteristics of steel can be divided into five types: austenitic type, austenitic - ferritic type, ferritic type, martensite type, precipitation hardening type. Stainless steel plate surface smooth, plasticity, toughness and high mechanical strength, resistance to acid, alkaline gas, solution and other media.
The chemical and electrochemical corrosion resistance of steel is better, second only to titanium alloy. According to different types of stainless steel, 304L stainless steel plate has different mechanical properties, including high strength, hardness, good plasticity, low strength but good corrosion resistance, medium mechanical properties, low strength but oxidation resistance.
304 stainless steel plate is austenite at high temperature. How does 304 stainless steel plate harden soft? After hot rolling, martensite transformation occurs during the cooling process, and high hardness martensite is obtained at room temperature. 304 stainless steel plate is the general name of stainless steel plate and acid resistant steel plate. Stainless steel plate is a kind of steel plate that can resist the corrosion of weak medium such as air, steam and water.
According to the performance characteristics and use of 304 stainless steel plate, can be divided into nitrate resistant stainless steel plate and sulfuric acid resistant stainless steel plate. According to the functional characteristics of the steel plate, it can be divided into low temperature stainless steel plate, non-magnetic stainless steel plate, easy cutting stainless steel plate and micro stainless steel plate.
To sum up, the above is 304 stainless steel plate processing need to pay attention to what matters of the main content, if you do not understand the place can call to consult our company.
