Stainless steel has been employed in many engineering applications ranging from pharmaceutical equipment to piping in the nuclear reactors and storage to chemical products. In this attempt, simulation of fatigue crack growth based on experimental results of austenitic stainless steel 304L was presented using AFGROW code when NASGRO mode laws adopted. Double through crack at hole specimen is use...

background: one of the methods used for joining metals together is welding, which can be carried out using different techniques such as electric spot welding. this study evaluated the effect of electric spot welding on the load defl ection rate of stainless steel and chromium-cobalt orthodontic wires. materials and methods: in this experimental-laboratory study, load defl ection rate of 0.016 ×...

The aim of this work is to determine the fatigue life of 316L stainless steel. The mechanisms of fatigue of 316L stainless steels were investigated and discussed. The fatigue tests were carried out at constant-amplitude cyclic loading with load ratio R=0.1. Scanning Electron Microscope (SEM) is then used to examine the fracture surface. The results show that the fatigue limit of 316L stainless ...

introduction: any decrease in friction between orthodontic wire and bracket can accelerate tooth movement in the sliding technique and result in better control of anchorage. the present study was carried out to decrease this friction by coating of zinc oxide nanoparticles (zno) on orthodontic wires and porcelain brackets. materials and methods: in this in vitro study, a combination of 120 0.019...

The evaporation of inertial confinement fusion first wall materials from unattenuated pellet X-rays and from radiation emitted by a cavit.y buffer qas is examined. The low vapor pressure and low X-ray attenuation coefficient of carbon give it a lower erosion rate than stainless steel, despite the larger thermal conductivity of Type 316 stainless steel. For the argon buffer gas containing 0.2% N...

Stainless steel interconnect materials used in solid oxide fuel cells and electrolysers need to be coated improve oxidation resistance mitigate Cr-vaporization. This work aimed explore the optimal steel/coating combinations suitable for use reversible stacks evaluated (Co,Mn)3O4 spinel, LaFeO3 perovskite, Ce/Co Y-based coatings, on AISI441 Crofer 22 APU steels. The coatings were based measureme...

Chloride-induced corrosion of carbon steel reinforcement is the main cause of deterioration of reinforced concrete (RC) structures in marine environments. One of the ways to protect RC structures from corrosion is to use corrosion-resistant stainless steel reinforcing bars. However, stainless steel is between six and nine times more expensive than carbon steel. Thus, its use can only be justifi...

Layers of high silica zeolites, synthesized with an organic structure directing agent (OSDA) and grown onto porous support structures, frequently suffer from the thermal stress during the removal of OSDA via the calcination process. The different thermal expansion coefficients of the zeolite and the support material, especially when stainless steel is used as a support, causes enormous tension ...

In this research work, the effectiveness of stainless steel sheet for the production of motor cycle exhaust muffler burn protector was investigated. Energy Dispersive X-Ray fluorescence method was used to determine the chemical composition of the stainless steel materials and exhaust muffler of the motor cycle. The stainless steel sheet was perforated and folded to frustum shape to achieve aero...
