Solution treatment. The main purpose of water quenching after heating the steel to ~ ℃ is to dissolve the carbide in austenite and keep this state to room temperature, so that the corrosion resistance of the steel will be greatly improved. As mentioned above, in order to prevent intergranular corrosion, solid solution treatment is usually used to dissolve CrC in austenite and then cool rapidly. Air cooling can be adopted for parts, and water cooling is generally adopted.Chinese brand cold rolled non oriented silicon steel strip (sheet) means: DW + times of iron loss value (at the frequency of Hz,GrenobleStainless steel penstock, the magnetic induction peak with sinusoidal waveform is the unit weight iron loss value of t) + times of thickness value.

In order to study the factors affecting the shear capacity of the jacket legs of the stainless steel pipe in pipe concrete-filled steel tubular offshore platform a total of concrete-filled steel tubular shear members were fabricated to study the effects of outer steel pipe material, concrete strength, void ratio and shear span ratio on the shear capacity of concrete-filled steel tubular in pipe. It is found that the shear strength of members increases with the decrease of void ratio and the increase of concrete strength; The larger the shear span ratio, the smaller the shear strength. Combined with the test, the empirical formula of shear capacity of concrete-filled steel tubular in pipe is proposed, which is analyzed and verified by ABAQUS finite element modeling software. The results show that the simulation is in good agreement with the test results. In order to study the axial compression performance of stainless steel tube concrete conduit leg and the axial compression performance of stainless steel concrete conduit leg, experiments are used to verify the correctness of the finite element model. The load displacement curves of specimens in groups were compared, and the effects of different void ratio, concrete strength, diameter thickness ratio and bone index on the axial compression performance of concrete-filled stainless steel tubular short columns under axial compression were analyzed. The results show that with the increase of concrete strength, the bearing capacity of specimens increases, but the ductility of specimens decreases; With the increase of void ratio and diameter thickness ratio, the bearing capacity of the specimen decreases; The bearing capacity of stainless steel tube concrete can be effectively improved by adding steel bone; Increasing the bone matching index of steel bone can improve the bearing capacity of the specimen. A compound forming process of double-layer stainless steel pipe for primary circuit main pipeline of station is designed, which solves the problem of limited length of finished products in traditional forging or casting process, and meets the special requirements of complex working environment on pipeline performance. The three roll cross rolling forming process of double-layer casing with outer layer -n austenitic heat-resistant stainless steel and inner layer cr-ni martensitic heat-resistant stainless steel was simulated and optimized by using DEFORM-D finite element simulation software. The internal and external deformation, stress-strain field and temperature field of double-layer stainless steel pipe were analyzed, and the optimal deformation parameter combination was obtained by orthogonal test. The simulation results show that in the process of three roll cross rolling, the large values of equivalent stress, equivalent strain and temperature are concentrated in the area between the outer tube and the roll, and the overall performance parameters of the outer tube are greater than those of the inner tube. The range analysis and variance analysis of orthogonal design test show that the optimal deformation parameter is rough rolling temperature deg; C. Feed angle & deg;, Roll speed: rmin. Objective to improve the existing connection mode of the braking system pipe system of railway freight cars, and accurately shape the end of the stainless steel pipe, so as to obtain the forged joint with better mechanical properties. According to the connection mode of the original pipe system and the plastic forming characteristics of steel pipe, a multi-step upsetting and extrusion process for the end of stainless steel pipe is proposed.

It contains more than % chromium, about % nickel and a small amount of molybdenum, titanium, it is possible to use it in refrigeration related engineering. Recently, suslx (cr Ti, Nb LC) and susl have been applied to frozen shells. Ferritic stainless steel has body centered cubic structure. When the material properties become weaker, sharp cracks will expand rapidly and cause brittleness. Austenitic series stainless steel will not produce brittleness because it has face centered cubic structure. Austrian stainless steel SUSL (cr-ni LC) and SUSL (cr-ni-mo-lc) shows that it still has superior impact characteristics at low temperature. However, pay attention to the precipitation of ferrite or martensite due to processing, and the tendency of embrittlement due to sensitized carbide or & sigma; equal heterogeneous precipitation.
