American Society for Testing and Materials (ASTM) tau tsim ntau yam qauv rau ntau hom khoom steel, nrog rau cov kaum sab xis steel. ASTM tus qauv rau cov kaum sab xis steel yog ASTM A36.
ASTM A36 yog ib qho kev qhia tshwj xeeb uas npog cov qauv steel duab, nrog rau cov ces kaum, cov kab, thiab kab teeb. Nws yog tus qauv siv dav hauv Tebchaws Meskas thiab feem ntau siv rau hauv kev tsim thiab kev tsim kho cov khoom siv hlau, nrog rau cov kaum sab xis steel.
ASTM A36 qhia txog cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab thiab qhov yuav tsum tau muaj rau cov kaum sab xis carbon steel. Cov txheej txheem no ua kom lub kaum sab xis steel tsim rau nws cov kev qhia tshwj xeeb muaj lub zog, ductility thiab lwm yam khoom uas yuav tsum tau siv rau kev siv cov qauv. Nws kuj tseem muab cov lus qhia rau kev tso cai hloov pauv hauv qhov ntev thiab kev kam rau siab rau cov kaum sab xis steel.
