4Stainless steel has the ability of atmospheric oxidation, that is, it does not rust. At the same time, it also has the ability of corrosion resistance in the medium containing acid, alkali and salt,Stainless steel checkered plate that is,Antique copper stainless steel plateSelection of materials corrosion resistance. However, its corrosion resistance changes with its own chemical composition, mutual state, service conditions and environmental medium type. For example, has absolutely excellent corrosion resistance in dry and clean atmosphere, in the sea fog with a lot of salt, it will soon rust, while stainless steel performs well. Therefore, not any kind of stainless steel can resist corrosion and rust at any time

The welding performance is also much better than that of ferritic stainless steel. Generally, preheating is not required before welding and heat treatment is not required after welding.

how muchjThe cold rolled steel strip has good strength and yield ratio, and the hot rolled steel strip has good ductility and toughness.

ICorrosion resistance of decorative stainless steel pipe the price of different series of stainless steel materials varies greatly. The corrosion resistance of more economical materials can not meet the higher application requirements, and the improvement of corrosion resistance of stainless steel materials by simple chemical passivation is limited. On the other hand, the traditional passivation treatment containing chromium salt has been gradually eliminated, and the passivation treatment of stainless steel has turned to the direction of environmental friendliness. Recently, citric acid passivation and silicon treatment on stainless steel surface have become a new research direction. The former has environmental protection characteristics because its passivation solution component does not contain chromium salt. After research it is found that silicon coupling agent is coated on the metal surface through chemical adsorption to form a protective silicon film with cross-linked network structure. The length of discoloration time of samples after different surface treatments was compared by blue dot method, the corrosion rate of samples after different surface treatments was distinguished by brine immersion test, and the salt spray resistance of samples after different surface treatments was distinguished by neutral salt spray test, energy spectrometer, X-ray diffraction X-ray photoelectron spectroscopy and total reflection Fourier transform infrared spectroscopy characterized the surface films of different surface treated samples, and analyzed the structural composition and corrosion resistance mechanism of different films. Professional sales of stainless steel plate, stainless steel coil, stainless steel belt, stainless steel pipe, high price sales door-to-door service, honest management! At present on-site settlement, there are few studies on the combination of citric acid passivation and silicon treatment of stainless steel. Therefore, this paper studies the difference of corrosion resistance of martensitic stainless steel Cr chemical passivation, silicon treatment and the combination of citric acid passivation and acid silicon system treatment and discusses the corrosion resistance mechanism of different films on its surface, which can provide reference for the new direction of stainless steel surface treatment, It has certain practical guiding significance. The corrosion resistance and mechanism of chemical passivation, silicon treatment and composite treatment of martensitic stainless steel were studied in this paper. The comprehensive comparison of the research results shows that the corrosion resistance of stainless steel treated with different surface treatments is different. The corrosion resistance of the sample treated with silicon alone is better than that treated with traditional dichromate passivation. The corrosion resistance of the composite treated sample treated with citric acid passivation and acid silicon system is further enhanced than that treated with acid silicon system alone. The composite treatment of citric acid passivation and acid silicon system treatment has excellent corrosion resistance and environmental protection characteristics, and is expected to replace the traditional dichromate passivation treatment. According to the film weight test results, the surface silicon film weight of the composite treated sample after citric acid passivation and acid silicon system treatment is lower than that of the sample after acid silicon system treatment alone, indicating that the excellent corrosion resistance of the composite film not only depends on the surface silicon film, but also benefits from its double-layer film structure.

Extrusion method means that the heated tube blank is placed in a closed extrusion cylinder, and the perforated rod moves together with the extrusion rod to extrude the extrusion part from the smaller die hole. This method can produce steel pipes with smaller diameter.

qProduction and manufacturing can be divided into hot-rolled pipe, cold-rolled pipe, cold drawn pipe, extruded pipe, etc.

oDStainless steel has the ability of atmospheric oxidation, that is, it does not rust. At the same time, it also has the ability of corrosion resistance in the medium containing acid, alkali and salt, that is, corrosion resistance. However, its corrosion resistance changes with its own chemical composition, mutual state, service conditions and environmental medium type. For example, has absolutely excellent corrosion resistance in dry and clean atmosphere but it is moved to In coastal areas, in the sea fog with a lot of salt, while stainless steel performs well. Therefore, not any kind of stainless steel can resist corrosion and rust at any time
