ASTM A320
Upeo
Hapo awali iliidhinishwa mnamo 1948, vipimo vya ASTM A320 hufunika chuma cha aloi na nyenzo za bolting za chuma cha pua kwa huduma ya joto la chini. Kiwango hiki kinashughulikia pau zilizokunjwa, za kughushi, au chujio ngumu, skrubu, vijiti na viungio vinavyotumika kwa vyombo vya shinikizo, vali, flanges na viunga. Kama vile vipimo vya ASTM A193, isipokuwa ikiwa imebainishwa vinginevyo, mfululizo wa nyuzi 8UN umebainishwa kwenye kipenyo cha kufunga kikubwa kuliko 1”.
Ufuatao ni muhtasari wa kimsingi wa alama chache za kawaida ndani ya vipimo vya ASTM A320. Idadi ya madaraja mengine ambayo si ya kawaida sana ya ASTM A320 yapo, lakini hayajaangaziwa katika maelezo hapa chini.
