Mbali

Povomerezedwa koyambirira mu 1936, izi zimagwiritsidwa ntchito kwambiri pomanga mafuta ndi mankhwala. Muyezo wa ASTM umakwirira zitsulo za alloy ndi zitsulo zosapanga dzimbiri zopangira zitsulo zopangira kutentha kwambiri. Izi zikuphatikiza zomangira zomwe zimagwiritsidwa ntchito paziwiya zokakamiza, ma valve, ma flanges, ndi zolumikizira. Ngakhale, nkhaniyi nthawi zambiri imapezeka mu ulusi wamtundu wa dziko (UNC), ngati ukugwiritsidwa ntchito pachikhalidwe, ulusi umatchulidwa 8 ulusi pa inchi (tpi) ya diameter pamwamba pa inchi imodzi.

Pansipa pali chidule chachidule cha magiredi ochepa. ASTM A193 imakhudzanso zina zambiri zomwe sizinafotokozedwe m'mafotokozedwe awa kuphatikiza B5, B6, ndi B16.
