ASTM A537 Classis 1,2,3 Vasa ferrea Boiler et Pressura

ASTM A537 Specificationis species est Standard Specification for Pressure Vasa Plates, Calor-tractata, Carbon-Manganese-Silicon Ferro adhibita in applicationibus fusionis pressionis vasorum et structurarum iunctarum. Applicatae typicae sunt pressionis vasorum ad moderandam et inferiorem temperaturam pertinentes, quae praestantem incisurae duritiem requirunt necnon API 650 et API 620 obtereres repositiones. Classis 1 materia in promptu est sicut Normalised et Classis 2 is available ut lamellae exstinctus & temperatae.
