304 stainless steel was tested under the media without Sulfate-reducing bacteria (SRB) and with SRB. The corrosion behaviors of 304 stainless steel in SRB and without SRB medium were studied by measuring the open circuit potential, the polarization curves and electrochemical impedance Spectrum,weight loss measurements to get the changes of fore-and-aft corrosion fouling. The open circuit potent...

An advanced simulation process of a stainless steel member in ANSYS technology is described this paper. A three-point bending test hot rolled material grade 1.4301 (AISI 304) has been conducted. The cross-section the beam was IPE80, with span supports equal to 240 mm. results experimental were compared materially and geometrically nonlinear numerical analysis. In order describe behavior materia...

Although deep drawing process in the macro scale are well developed, the known concepts cannot be applied to micro deep drawing through directly scale down the specimen and tooling size due to the so-called size effects. Therefore, tensile test and micro deep drawing experiments were conducted to generate the knowledge for the micro deep drawing process. Stainless steel 304 foils with 4 differe...

Cryogenic treatments are increasingly used to improve the wear resistance of various steel alloys by means of transformation of retained austenite, deformation of virgin martensite and carbide refinement. In this work the nanotribological behavior and mechanical properties at the nano-scale of cryogenically and conventionally treated AISI 420 martensitic stainless steel were evaluated. Conventi...

an artificial neural network (ann) model is developed for the analysis, simulation, and prediction of the austenite reversion in the thermo-mechanical treatment of 304l austenitic stainless steel. the results of the ann model are in good agreement with the experimental data. the model is used to predict an appropriate annealing condition for austenite reversion through the martensite to austeni...

Protective coating is an effective way to extend materials’ high-temperature service life. In order improve the oxidation resistance of AISI 304 stainless steel, mullite films with different layers were successfully prepared by sol-gel method and sintering process on surface steel. The effect film steel at 900 °C for 100 h was studied. analysis results kinetics, X-rays diffraction (XRD), scanni...

Hard turning of martensitic stainless steel is gaining importance in all manufacturing sectors like automobile and aerospace industries. Machinability of materials depends on surface roughness, tool wear, cutting forces, specific cutting pressure and work material hardness. In this research hard martensitic stainless steel AISI 440 C and SCM 440 alloy steel was used as work materials. CBN and P...

vanillin offers interesting possibilities for corrosion inhibition because of its safe use and highsolubility in water. the effect of vanillin on the corrosion inhibition of aisi 304 stainless steel in0.5m h2so4 solution has been studied using potentiodynamic polarization and electrochemicalimpedance spectroscopy (eis). furthermore, this paper demonstrates that the electrochemical noise(en) tec...
