tSolution 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，304 stainless steel plate but it is not easy to rust compared with other steel grades. Many people will think that the stainless steel pipe is not rusty and water cooling is generally adopted.
Stainless steel pipe will rust? Stainless steel pipe is a food grade stainless steel pipe recognized by the state. It is not absolutely non rusting，Plate embossed stainless steelChanges in market pattern especially the stainless steel pipe has high nickel content， which is more difficult to rust. If it is rusty， they will doubt whether it is fake， whether it will be replaced by stainless steel pipe， or there is a problem with the raw materials of the steel strip. In fact， these questions and judgments are one-sided views on the lack of understanding of stainless steel pipes. Stainless steel pipes may also produce rust and rust spots under certain conditions.

For example， some common austenitic stainless steels are marked with ， ， and ， martensitic stainless steels are marked with and C， duplex (austenitic ferrite)， stainless steels，tisco stainless steel sheet,taigang stainless steel sheet,stainless steel sheet,stainless steel coil,stainless steel strip,stainless steel tube-TISCO Stainless Steel Co.,Ltd precipitation hardening stainless steels and high alloys with iron content less than % are usually named by patent name or trademark.
Umarket priceDo a good job of preliminary data research. In the highly competitive market， stainless steel pipe dealers should go deep into the hinterland. It is essential and crucial to do a good job of pre market data research; Only by fully grasping consumer demand trends， habits and other data can we have more confidence to compete for market share. Therefore， the editor of stainless steel pipe believes that in-depth data mining and comprehensive market analysis are powerful for stainless steel control manufacturers in this movement.

Quality improvementvThe resistance， coefficient of linear expansion， thermal conductivity， quality， hot melt and magnetism of stainless steel pipe will change greatly at low temperature. Resistance， linear expansion coefficient decreases at low temperature; The thermal conductivity and mass heat capacity decrease sharply at low temperature; Youngs modulus (longitudinal modulus) increases when the temperature decreases. Because the austenitic series stainless steel pipe has MS point (martensite start temperature or martensite formation temperature) at low temperature (subzreo temperature)， martensite can be formed when it is kept below MS point. The formation of martensite at low temperature makes the representative steel sus (Cr-Ni) of austenitic stainless steel non-magnetic at room temperature and magnetic at low temperature.
OThe ice load is the main control load of offshore platform in severe cold area， which has high requirements for the shear bearing capacity of the conduit leg of offshore platform. 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， bearing capacity and local strain relationship of members under different conditions， 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， 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. By comparing the load displacement curves of specimens in groups， 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 are 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 composite forming process of double-layer stainless steel pipe for primary circuit main pipe of nuclear power plant 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 pipe performance. The three roll cross rolling 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 distribution of double-layer stainless steel pipe were analyzed The parameter combination of optimal deformation is obtained by designing orthogonal test. The simulation results show that the large values of equivalent stress， equivalent strain and temperature are concentrated in the contact 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. Through range analysis and variance analysis of orthogonal design test， the optimal deformation parameter is rough rolling temperature deg; C. Feed angle & deg;， Roll speed: rmin.
