Descriptio Brevis:

Tubi Chalybis Inoxidabilis Duplex 2205. Chalybs duplex late adhibitus, magnam fortitudinem et resistentiam corrosionis in variis acidis organicis, acidis anorganicis, aquis refrigerantibus aggressivis et mixturis hydricis H2S/NaCl coniungens. Mixtione fere aequali austeniti et ferriti, praebent limitem elasticitatis 30% maius et vires tensiles paulo maiores quam austenitica nitrogenium continentia comparabilia. Alta resistentia corrosionis generalis et praesertim corrosionis foveolatae et fissurarum. Resistentia earum fissurarum corrosionis sub tensione in chloridis neutris superior est quam austenitarum. In ambitu acidico cum alto chlorido vel moderate acido, ubi fissurae sub tensione hydrogenii vel sulfidi probabiliores sunt, austenitica altioris mixturae etiam consideranda sunt. Valores impetus alti sunt et temperaturae transitionis materiarum basium variant circa –50°C. Tamen, proportio et orientatio ferriti in suturis et materiis basium tenacitatem ad temperaturas infra zero significanter afficere possunt. Expositio ad temperaturas moderatas et altas et refrigerationem minus rapidam fragilitatem causare potest.
