At low temperature, the company specializes in selling stainless steel plates, coils, belts and tubes with quality assurance. The company specializes in selling, timely supply and high cost performance. It has become the first choice brand for many wire products. Welcome to buy! Ferritic stainless steel tubes have low temperature brittleness like carbon steel, while austenitic steel does not. Therefore, ferritic or martensitic stainless steel produces low temperature brittleness Temperature embrittlement, but austenitic stainless steel or nickel base alloy does not show low temperature embrittlement. Sus (Cr), SUS of ferritic stainless steel pipe (cr) and others show a sharp drop in impact value at low temperature. Therefore, when the embrittlement temperature is improved in the range of - ℃ to - ℃, it is possible to use it in freezing related projects SUSL has applied suslx (cr Ti, Nb LC) and susl (cr Mo Ti Nb LC) to the shell of refrigeration appliances. Ferritic stainless steel has body centered cubic structure. When the material properties become weak, sharp cracks will expand rapidly and cause brittle failure. Austenitic series stainless steel will not produce brittle failure because it is face centered cubic structure. Arctech has invested in stainless steel (cr-ni-lc) and SUSL (cr-ni-mo-lc) show that they still have superior impact characteristics at low temperature. However, pay attention to the precipitation of ferrite or martensite due to processing, and the tendency of embrittlement caused by carbide or & sigma; equal heterogeneous precipitation due to sensitization.

consumptioneNo matter under dynamic load or static load, it has higher energy absorption capacity than austenitic stainless steel, which has obvious advantages and practical application value for structural parts to deal with sudden accidents such as collision and explosion. Compared with austenitic stainless steel, duplex stainless steel has the following disadvantages: its universality and versatility are not as good as austenitic stainless steel. For example, its service temperature must be below ℃.

NFormula for hydraulic test pressure of stainless steel welded pipe for weight calculation fluid (gbt-): where: P - test pressure, MPa; R - stress, taking yield point of %, MPa; s - nominal wall thickness of steel pipe, mm; D - Nominal outer diameter of steel pipe, mm.

The stainless steel pipe installed on the pipeline support can be corroded by ppm chloride ion and ppm residual chlorine in an aerobic environment. For carbon steel structural supports, the pipeline shall be insulated to prevent corrosion due to potential difference and the external insulation cotton shall be wrapped for anti-corrosion treatment. Remember, never use glue and other materials that contain chloride ions, halogens and other corrosive effects on stainless steel pipes.

eThe effect of different stabilizers on the stability of ferritic stainless steel during pickling in base solution was studied by means of weight loss curve and scanning electron microscope. The results show that under the experimental conditions, both complex stabilizer HF and adsorption complex stabilizer -sulfosalicylic acid can completely remove the oxide layer on the surface of stainless steel The effect of adsorbing complex stabilizer -sulfosalicylic acid is obviously better than that of complex stabilizer HF in the stability effect and the flatness of the research results on the properties and microstructure of stainless steel surface s stainless steel pipe after pickling. The deformation behavior at high temperature at ℃ and strain rate of . ~ s-. The rheological stress curve is drawn according to the compression experimental data; based on Arrhenius relationship and considering the strain Factor, and the dynamic recrystallization volume fraction model is established based on the s stainless steel pipe equation. The results show that in the process of thermal deformation of s stainless steel pipe, the flow stress corresponding to lower temperature and faster strain rate is also large; the coupling of stress variable factors The correlation coefficient between the rheological stress of the constitutive model s stainless steel pipe and the experimental value is . , and the average relative error is only %. The model can better predict the deformation resistance of L stainless steel in the process of thermal deformation

zIExtrusion 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.
