The initial material cost of structural stainless steel is about four times that of structural carbon steel, due largely to the expense of the alloying elements and the relatively low volume of production. Given broadly similar structural performance, additional areas of benefit need to be identified and exploited in order to establish stainless steel as a viable alternative material for constr...

This paper presents a series of tests on cold-formed stainless steel bolted connections. The test specimens were fabricated from three different types of stainless steel, including austenitic stainless steel EN1.4301 (AISI 304) and EN1.4571 (AISI 316Ti having small amount of titanium) as well as lean duplex stainless steel EN1.4162 (AISI S32101). The material properties of the three types of st...

The inhibitive and adsorptive properties of Sesmum indicum eco-friendly oil for stainless steel corrosion in hydrochloric acid was investigated using weight loss technique as well as electrochemical technique. The result has proved that the oil is excellent inhibitor for stainless steel in hydrochloric acid. The inhibition efficiency of oil for stainless steel increased with increase the amount...

An attempt made to optimize the operating parameters involved in an autogenous pulsed Nd: YAG laser welding process of similar and dissimilar combinations of butt joint of 2 mm thick 316 L stainless steel and mild steel. Influence of prominent laser welding parameters such as average peak power, defocus position, spot position, and shielding gas were investigated for welded joints considered. T...

Flexible intramedullary nails are commonly used to treat femoral fractures in children. This study evaluated the biomechanical differences between stainless steel and titanium nails when securing transverse and comminuted fractures in a synthetic femur model. Retrograde flexible stainless steel and titanium nails placed in a divergent "C" pattern were mechanically tested, and axial rotation and...

This paper presents a study to evaluate the mechanical properties of commercially available GRP composite fasteners for the fairing band assembly components of the hull mounted sonar domes on Canadian frigates. The study was undertaken as part of an effort to develop an all-composite fairing band assembly for a stainless steel sonar dome, to eliminate corrosion problems that occur with the use ...

Initiation of corrosion on reinforcing bars occurs when a critical chloride concentration is achieved. A universal value for the chloride concentration that causes depassivation has not been agreed upon for carbon steels due to a variety of experimental factors. The chloride threshold depends on the rebar material, rebar surface condition, testing environment, method of detection, definition of...

Introduction: During sliding mechanics, frictional resistance is an important counterforce to orthodontic tooth movement; which must be controlled to allow application of light continuous forces. objective: To investigate static and kinetic frictional resistance between three orthodontic brackets: ceramic, self-ligating, and stainless steel, and three 0.019×0.025” archwires: stainless steel, ni...

This study demonstrates the anti-Staphylococcus aureus properties of stainless steel surfaces coated with zeolite containing 2.5% silver and 14% zinc ions. Stainless steel panels with and without the heavy-metal-containing coatings were inoculated with S. aureus and incubated at room temperature. Survival of S. aureus was significantly reduced by the silver/zinc coatings within 1 h. Many hospit...
