Stainless steel bar each chemical identification coup things are good and bad points to buy things fear is fakes are now made of stainless steel products in many industries, will use stainless steel for production, then how to identify counterfeit stainless steel stainless steel door , we need to take measures and methods. 1, Chongqing magnetic stainless steel processing test method - Magnetic test method is the most primitive of the most common distinction austenitic stainless steel and the easiest way to ferritic stainless steel, austenitic stainless steel is non-magnetic, but by a large reduction after cold with a slight magnetic; and pure chrome steel and low alloy steels are strongly magnetic. 2, the point of nitric acid test method - a notable feature is the stainless steel of concentrated nitric acid and dilute nitric acid has inherent corrosion resistance, this performance so that it can easily be distinguished from most other metals or alloys. However, high carbon steel type 420 and 440 points during nitric acid test is slightly corroded, non-ferrous metals encountered in concentrated nitric acid corrosion immediately, and dilute nitric acid has a strong corrosive to carbon steel. Chongqing stainless steel processing smelting process route Chongqing stainless steel processing smelting raw materials, mainly metal materials and alloys. Scale production reached 50,000 t of stainless steel over stainless steel smelting production process should not be one-step, two-step or three-step selection should organize production method. Because of various factors followed rapidly changing market, the production process selection should have some flexibility. Under normal circumstances, the three-step method of production cost is higher than the two-step, but because of the combined effects of these various factors, and finally to the actual situation of embossed stainless steel plate production scale of products and raw materials premise solutions, such as a detailed analysis, fair selection . Ferrochrome and chrome ore containing water has a dual nature of the metal materials and alloys. Alloys including high, medium and low carbon ferrochrome, electrolytic nickel-iron, nickel or NiO, ferrosilicon, ferromanganese. Scale production of stainless steel smelting production process of selection, has a restraining effect. Small-scale production of stainless steel moldings, general annual output of 30,000 t of stainless steel, stainless steel scrap have a reliable guarantee of return, you can use one-step production process of smelting. Our TISCO stainless steel one, five Baoshan Steel Corporation and Dalian Steel and other companies are using the production process. Scrap metal material including the return of ordinary scrap and blast furnace hot metal. When using blast furnace hot metal material, because of the high silicon, sulfur, phosphorus content in hot metal is necessary to improve the senior line of the first three off the handle, get low sulfur, phosphorus stainless steel liquor, and then refined through a refining furnace. Most of the current selection of AOD refining furnace or converter composite top and bottom blowing converter, if you want to lower the smelting [C] or low [N] stainless steel, after step process also configure RH-OB or VOD vacuum refining.
