.Rheological and thermal changes in the quenching process of decorative stainless steel pipe the cooling characteristics of submerged quenching of stainless steel plate are numerically simulated by using the Euler multi fluid model in AVL fire software, and the numerical results are compared with the experimental results. In the research, the quenching medium is water. The mass, momentum and energy equations of gas-liquid two-phase of quenching medium and the quenching heat conduction equation of stainless steel workpiece are solved by numerical simulation. Based on the principle of equal heat flux between quenching medium and workpiece, the temperature field of quenching medium and workpiece is solved by coupling. The comparison between the numerical simulation and experimental results of decorative stainless steel pipe shows that the numerical simulation results of workpiece temperature are in good agreement with the experimental data. The model can reliably simulate the quenching process of workpiece, and can be extended to the multiphase flow simulation in complex system to guide the actual production. The single pass thermal simulation compression experiment of 13Cr super martensitic stainless steel was carried out by Gleeble thermal simulation tester to study the thermal deformation behavior at 950 ~ 1200 ℃ and strain rate of 0.1 ~ 5 s-1, and the microstructure evolution law of grains under different conditions was analyzed; Based on Sellars hyperbolic sinusoidal model, the flow stress constitutive equation of 13Cr super martensitic stainless steel was constructed. The results show that the peak stress decreases with the increase of deformation temperature and the decrease of strain rate; With the increase of deformation temperature, the grain grows and coarsens gradually. With the increase of strain rate, the dynamic recrystallized grains are obviously refined. The thermal deformation activation energy Q = 519580.9 JMOL of decorative stainless steel pipe is calculated, and the expression of Zener Hollomon parameter is obtained. Different feedstocks were prepared by mixing cr17mn11mo3n nickel free austenitic stainless steel powder prepared by aerosol and wax based binder. The effects of binder ratio and powder loading on the rheological properties of feed were studied by rh5000 high pressure capillary rheometer. Non Newtonian index n, viscous flow activation energy E and comprehensive rheological factor alpha are calculated by second order model regression analysis; STV. The results show that the prepared feeds are pseudoplastic fluid. The binder system was composed of 65% microcrystalline wax (MW), 25% high density polyethylene (HDPE), 5% ethylene vinyl acetate copolymer (EVA) and 5% stearic acid (SA). The powder loading was 68 vol%. The feed had good comprehensive rheological properties. In order to study the cementitious properties of stainless steel AOD slag, stainless steel AOD slag was used to replace some cement, and its effects on the working properties and mechanical properties of cement mortar were studied. The results show that using stainless steel AOD slag to replace cement from 0 ~ 50%, with the increase of the content of stainless steel AOD slag, the water consumption of standard consistency of cement first decreases and then increases. When the content is 30%, the water reduction effect of stainless steel AOD slag is good; With the increase of the content of stainless steel AOD slag, the strength of cement mortar decreases in turn, indicating that the cementitious activity of stainless steel AOD slag is small.

From the perspective of metallography, because stainless steel contains chromium, a very thin chromium film is formed on the surface, which is separated from the corrosion resistance of oxygen invaded in the steel.

.Cold rolled oriented silicon steel strip consists of nominal thickness (expanded by 100 times) + code G: ordinary material, P: high oriented material + guaranteed iron loss value (the value after expanding the iron loss value when the frequency is 50Hz and the large magnetic flux density is 7T by 100 times). For example, 30g130 indicates that the thickness is 0.3mm and the guaranteed value of iron loss is ≤ 3 cold rolled oriented silicon steel strip. Liaocheng Suntory stainless steel provides electroplated tin plate and hot-dip galvanized plate: electroplated tin plate, electroplated tin sheet and steel strip, also known as tinplate. The surface of the steel plate (belt) is plated with tin, inner and outer sheath of cables it can be used as packaging material for cans, instrument and telecommunication parts, flashlight and other hardware.

The cold working process performance and cold forming performance are much better than that of ferritic stainless steel.

As we all know, stainless steel pipe has a strong ability of atmospheric oxidation and is not easy to rust under normal circumstances & ldquo; Stainless steel pipe & rdquo; Hence the name of. But what I want to tell you today is that stainless steel pipes will also rust. I believe many friends will be surprised! I believe there are many people who don't know how to explain to customers! Next, let's popularize science!
