Abstract. Stainless steel is one of the most widely used materials in current orthodontics.Archwires, brackets, bands, ligatures, tubes, among other appliances, aremanufactured using different types of this alloy. The first evidence of the use ofthis alloy in the orthodontic field dates back to the mid-1920s, when it was introducedas a material to manufacture wires. The alloy has ever since gained popularityamong orthodontists and its further development has led to its widespread usein today’s different orthodontic techniques. Despite being available for more than80 years, and the fact that most orthodontists use it on a daily basis, there is still alack of knowledge about the basic principles, composition, and properties of thismaterial by these professionals. Therefore, the purpose of this literature review isto discuss the main characteristics and properties of stainless steel that are usefulin the orthodontic practice for orthodontists to take advantage of this remarkablematerial.

Efficient inspection of stainless steel overlays appears to present a particularly challenging problem due to the anisotropy that is characteristic of that material. An improved inspection technique may be available, however, when the dissimilar properties of the overlay and the base material are utilized. Higher order mode Rayleigh waves which at high frequencies remain confined to the upper layer of the stainless steel material are demonstrated to be able to detect welding defects in the overlay material in a field some distance away from the probe. With this technique, a larger area may be scanned with each probe placement rather than the point contact probe inspection method that is typically used.

Stainless steel; Aspheric mould; Ultra-precision turning; Magnetorheological polishing The ultra precision turning and the inclined-axis type of magnetorheological polishing were introduced for the small aspheric mould of stainless steel. The method was based on the principle of two kinds of processing methods, and the processing feature of stainless steel material. Firstly, the ultra-precision turning was employed to shape aspheric surface rapidly and obtain a relatively good surface. And then, the inclined-axis type of magnetorheological polishing as the final finishing was used to decrease sub-surface damage to obtain better precision. Several of experiments were carried out, the experimental results show that surface roughness can be achieved for Ra 0.0073μm.

Clad plates welding of stainless steel welding on interlayer between grass roots and the transition layer is a key technology.Structure and properties of welded joints is very uneven,and there have often welding repair cracks. Clad plates of stainless steel material is used to weld under construction in the Southern link’s railway bridge for the first time at home .However, there occurs welding warpage of the convex parts and roughness appears excessive on the overall clad plates and severe deformation, and the quality of railway bridge is affected seriously. Reasons of the impacting welding quality are analyzed and specific measures to control them are proposed and the construction program is optimized.the efficiency and quality of welding can be improved ,a good foundation for the compound plates welding is layed,it will be contribute to ensure the overall quality of the welding quality of railway bridge especially the use of clad plates.

This paper presents a new method for sputtering solar selective absorber coatings. Radio frequency magnetron reactive sputtering created stainless steel/stainless steel nitride (SS/SS-N) cermet (ceramic-metal composite) thin films under varied nitrogen gas flow ratios. In this present study, a stainless steel material is used for one-target sputtering to manufacture a solar selective absorber film having good solar absorptance of 0.91 and low thermal emittance of 0.06. This sputtering process shows considerable and stable usefulness due to the anti-oxidation and single target. Optical constants n and k have been determined by spectroscopic ellipsometry for cermet composite in a reactive gas flow from 0 percent to 50 percent. Based on the nitrogen content of the film, we used a different oscillator to analyze the film. When the nitrogen gas flow reaches 10 percent, the sputtered film has a significant transformation from metal to cermet properties. When the nitrogen gas flow goes above 17.5 percent, then the film transforms to a dielectric film which can be an anti-reflection layer. A solar absorptance of 0.92 was accepted as the theoretical prediction of optimal selective solar-absorbing three-layer processes which shows that the experimental results agree well with the theoretical prediction.
