ASTM A320
Scope
Pakutanga yakatenderwa muna 1948, iyo ASTM A320 yakatarwa inovhara alloy simbi uye Stainless simbi bholting zvinhu zveyakadzika tembiricha sevhisi. Iyi chiyero inovhara, yakaumbwa, kana kuomesa mbariro dzakaomeswa, mabhaudhi, masiruu, zvitubu, uye mabhaudhi ezvitubu anoshandiswa kumanikidza midziyo, mavharuvhu, maflange, uye mafittings. Kufanana neiyo ASTM A193 yakatarwa, kunze kwekunge yatsanangurwa neimwe nzira, iyo 8UN tambo yakatevedzana inotsanangurwa pane fastener yakakura kupfuura 1 ”padhayamita.
Pazasi pane pfupiso yekutanga yeashoma emagiredhi akajairwa mukati meiyo ASTM A320 yakatarwa. Hwakawanda hwemamwe magiredhi asina kujairika eASTM A320 aripo, asi asina kufukidzwa mune tsananguro pazasi.
