a protective film will be attached to the surface of the stainless steel plate to ensure the gloss of the surface and prevent scratches. It can also effectively prevent scratching during transportation. The outer protective film is also a very important point. If the protective film with poor quality is placed for a long time

In general, the protective film will be damagedThe fingerprint treatment process can obtain fingerprint free effect in the treatment of stainless steel mirror plate, wire drawing plate,Lebanon201 professional stainless steel pipe, frosted plate and etching plate, and can improve the anti rust function.Lebanon,It is widely used in steel, crude oil, metallurgical industry, power engineering, water supply and drainage, engineering construction and other fields.Iron oxide and spinel can also be oxidized by salt to become loose ferric oxide, the formed oxide is partially peeled off and settled at the bottom of the furnace in the form of sediment. Alkaline salt melting pretreatment process flow: steam degreasing → Preheat（Liberia,Electroplating is used to ensure the surface of carbon steel, but as people know, this protection is only a thin film. If the protective layer is, the steel below begins to rust.: stainless steel plate: it can be divided into cold-rolled plate and hot-rolled plate. Its surface has bright surface, there are B plate and Ba plate In addition, other light colors can be plated according to customer requirements The main specifications of plates are: m * m, m * m, m * m, m * M, m * m, ifAfter molten steel casting, stainless steel pipe fittings generally adopt the same vertical vertical bending or arc continuous caster as carbon steel. The refined molten steel is poured into the ladle, the ladle to be poured is transferred to the top of the tundish mouth through the rotary table, and then the molten steel is tundish through the long nozzle. Steel in Tundish

There are three elements in the specification and size of: thickness, width and length.The specific steps of the continuous casting billet process of stainless steel pipe fittings are as follows: according to different steel grades, the vibration process of the mold is matched with the protective slag, which can improve the yield of %, so as to improve the yield of molten steel.Stainless steel has two classifications: one is divided into chromium stainless steel and chromium nickel stainless steel according to the characteristics of alloy elements; The other is divided into m stainless steel, f stainless steel, a stainless steel and A-F duplex stainless steel according to the microstructure of steel under normalizing state.Service first, price composition of corrugated stainless steel plate ceiling: material cost: including corrugated stainless steel plate, wood base (or keel), support frame and consumables. Generally, it accounts for about one third of the quotation.Mode,Lebanon201 high quality stainless steel pipe, load & mdash; Displacement curve and load & mdash; The effects of high temperature, wall thickness and length diameter ratio on the ultimate bearing capacity,Lebanon420 high quality stainless steel plate, but it will reduce the ultimate bearing capacity of the specimen; After high temperature,It can be found that the finite element model can well predict the failure mode of stainless steel square pipe string after high temperature. In order to make the outer surface roughness of cold processed precision stainless steel pipe meet the product quality requirements, an intelligent polishing equipment for the outer surface of precision stainless steel pipe is developed. The equipment adopts self

All the four new materials show good corrosion resistance, which is obviously better than the traditional TP material and the high chromium material tested in the past. At present, they are more suitable for the high-temperature alkaline environment on the flue gas side of the boiler in biomass power plant. Stainless steel has high chemical stability and excellent comprehensive mechanical properties,Variable cost,There is also a spectrometer detection method, which is a relatively simple and fast way.Stainless steel is a thin, firm, fine and stable chromium rich oxide film (protective film) formed on its surface Prevent oxygen atoms from penetrating and oxidizing to obtain corrosion resistance Once for some reason, the film is constantly, and the oxygen atoms in the air orIt is concluded that the corrosion resistance of duplex stainless steel is equivalent to that of L stainless steel, while the mechanical properties are better than L, the elongation is reasonable, and the cost is lower than that of L and .Lebanon,The chromium content of stainless steel plate is -%, and the Ni content is -%. Due to its high nickel content, it has been greatly strengthened in terms of corrosion prevention. It can be used in ordinary environment for more than years and in bad environmentEqual to . Due to the dual phase micro element structure has excellent mechanical properties and reasonable elongation. In ASTM standards in some areas, the sample length in tensile strength test is usually mm instead of mm Therefore, the elongation of A is more accurate than that of AMolten salt has strong oxidizing power low melting point and small viscosity. In the production process, only the sodium halo is analyzed, and the halo content is not less than % (WT). It is treated in a salt bath furnace at a temperature of ~ ℃ for minutes for ferritic stainless steel and minutes for austenitic stainless steel. Again,
