ASTM A268 Steel Pipe
Ity fanondroana ity dia mirakitra mari-pahaizana maromaro amin'ny hatevin'ny rindrina, fantsona vy tsy misy kilema ho an'ny serivisy manohitra ny harafesina sy ny mari-pana ambony.Ny ankamaroan'ireo naoty ireo dia fantatra amin'ny anarana hoe "traight-chromium" ary miavaka amin'ny maha-ferromagnetika azy.Ny roa amin'ireo naoty ireo, TP410 sy UNS S 41500 (Tabilao 1), dia azo ekena amin'ny fanamafisana ny hafanana amin'ny alàlan'ny fitsaboana hafanana, ary ny chromium avo lenta, ferritic alloys dia mora tohina amin'ny tsy fahampian-tsakafo amin'ny fampangatsiahana miadana amin'ny hafanana mahazatra.Ireo endri-javatra ireo dia tokony ho fantatra amin'ny fampiasana ireo fitaovana ireo.Ny Grade TP439 dia ampiasaina indrindra amin'ny serivisy tanky mafana ary tsy mitaky fitsaboana hafanana aorian'ny lasantsy mba hisorohana ny fanafihana ny faritra voakasika amin'ny hafanana.
