ASTM A 320 Cov Lus Qhia

Scope
Ameslikas pom zoo nyob rau hauv 1948, ASTM A320 specification npog alloy steel thiab stainless hlau bolting cov ntaub ntawv rau kub tsis tshua muaj kev pab cuam. Cov txheej txheem no npog dov, forged, los yog strain hardened tuav, bolts, screws, studs, thiab stud bolts siv rau siab hlab ntsha, li qub, flanges, thiab fittings. Ib yam li ASTM A193 specification, tshwj tsis yog tias tau teev tseg, 8UN xov series tau teev nyob rau ntawm fastener loj dua 1 "inch.
Hauv qab no yog cov ntsiab lus tseem ceeb ntawm ob peb ntawm cov qib sib xws hauv ASTM A320 specification. Ib tug lej ntawm lwm cov qib qis dua ntawm ASTM A320 muaj nyob, tab sis tsis suav nrog hauv cov lus piav qhia hauv qab no.
