Korohia 20

Korohia 20hekowiri tira austenitici whakawhanakehia mo nga tono whai waahiwaikawa pungatara. Ka kitea ano e tana parenga waikura etahi atu whakamahinga i roto i tematū,petrochemical,whakangao hiko, akirihouahumahi. Alloy 20 ātetepokaapūhaumāota katotete waikura, pai ake304kowiri tira me te rite ki316Lkowiri tira. Ko ona ihirangi parahi ka tiakina mai i te waikawa sulfuric. Ko te Alloy 20 he maha nga wa ka whiriwhiria hei whakaotipakaruhanga waikura ahoteararuraru, tera pea ka puta ki te 316L kowiri.
