Stainless steel wrought wires used as clasp arms for removable partial dentures in Thailand were compared with those used in some other countries (in the as-received condition) in terms of flexibility, Vickers microhardness and composition. The results showed that there were significant differences (P< or =0.05) among the wires. A Japanese stainless steel wire (SK) was obviously different from the others. It had the lowest proportional limit and microhardness, but its flexibility was almost the same. The chemical composition of each wire was not greatly different. The wires were about 18-20 wt% chromium and 8-9 wt% nickel, except for the SK wire, which had about 12 wt% nickel.
将泰国用于可摘局部义齿卡环臂的不锈钢锻造丝与其他一些国家使用的(收货状态下)不锈钢锻造丝在柔韧性、维氏显微硬度和成分方面进行了比较。结果表明,这些丝之间存在显著差异(P≤0.05)。一种日本不锈钢丝(SK)明显与其他丝不同。它的比例极限和显微硬度最低,但其柔韧性几乎相同。每种丝的化学成分差异不大。除了含镍量约为12 wt%的SK丝外,其他丝的铬含量约为18 - 20 wt%,镍含量约为8 - 9 wt%。
