ASTM A320

Oke
Na mbụ kwadoro na 1948, nkọwapụta ASTM A320 na-ekpuchi alloy steel na igwe anaghị agba nchara maka ọrụ okpomọkụ dị ala. Ọkọlọtọ a na-ekpuchi mkpanaka akpọrepu, kpụrụ akpụ, ma ọ bụ kpachie mmanya siri ike, bolts, skru, studs, na stud bolts ejiri maka arịa nrụgide, valvụ, flanges na akwa akwa. Dịka nkọwapụta ASTM A193, ọ gwụla ma akọwapụtara ya ọzọ, akọwapụtara usoro eri 8UN na fastener karịrị 1” na dayameta.
N'okpuru bụ nchịkọta isi nke ole na ole n'ime akara ule dị n'ime nkọwa ASTM A320. Ọtụtụ akara ule ndị ọzọ na-adịghị adịkarị nke ASTM A320 dị, mana ekpuchighị ya na nkọwa n'okpuru.
