driver (Figure 1), is made from stainless steel and is used to hold a suturing needle during surgical procedures. To maintain a firm grip on the needle, the jaws have textured patterns either etched directly on the stainless steel or on a replaceable tungsten carbide insert, which grips the suture needle more precisely and wears out much slower than stainless steel. Needle holders with tungsten...

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 ×...

Abstract The most relevant criticalities of parts produced by material extrusion additive manufacturing technologies are lower mechanical properties than standard performances, the presence pores caused method, and issues related to interface between layers rods. In this context, heat treatments can be considered an effective solution for tailoring behavior different application fields, especia...

The throughput of the injection molding process is restricted by cooling time each cycle which accounts for three-fourths time. Manufacturing molds out copper or alloys can reduce because their high thermal conductivity, but mold life reduced has much lower hardness and strength than traditional materials such as steels. By layering steel onto using directed energy deposition, advantages both b...

Using uniaxial tensile and hardness testing, we evaluated the variability and anisotropy of the mechanical properties of an austenitic stainless steel, UNS S17400, manufactured by an additive process, selective laser melting. Like wrought materials, the mechanical properties depend on the orientation introduced by the processing. The recommended stress-relief heat treatment increases the tensil...

Objective: Investigate the effects of heat-activated NiTi and stainless steel wires to evaluate potential changes in the position of mandibular incisors in extraction cases as correlated with treatment length. Method: The sample consisted of 36 individuals of both genders, Brazilian Caucasians with mean initial age of 15 years and 5 months with Class I and Class II malocclusions, divided into t...

Closed coil spring is an additional tool in a fixed-orthodontic treatment. NiTi orthodontic alloy that has shape memory and elasticity features, while stainless steel properties of malleability, low friction between wire-bracket, as well easy soldering welding. Various closed springs have been widely studied, but research on the stretching time remains unclear. This study aimed to determine eff...
