A36 A992 Lub kaum ntse ntse sib npaug

A36 steel yog cov hlau muaj pes tsawg leeg tsim los ntawm ASTM (American Society for Testing and Materials). Nws yog cov hlau me me, tseem hu ua cov pa roj carbon tsawg, nrog cov ntsiab lus carbon ntawm 0.25%–0.3%. kab teeb. Lub koom haum kev lag luam kev lag luam piav qhia tus qauv li no: "ASTM A992 (Fy=50 ksi, Fu=65 ksi)) yog cov khoom siv tshwj xeeb rau cov duab dav dav, tau hloov ASTM A36 thiab A572 qib 50.

Yuav ua li cas A36 ua

A36 yog tsim nyob rau hauv ib tug zam zoo li feem ntau carbon steels. Ua ntej, hlau ore thiab thee tau muab tso rau hauv ib lub qhov cub. Cov impurities raug hlawv tawm thiab cov ntsiab lus alloying ntxiv rau cov hlau molten. Thaum cov tshuaj muaj pes tsawg leeg ntawm A36 steel tiav, nws yog solidified nyob rau hauv ib tug rectangular ingot. A36 steel feem ntau yog kub dov. Qhov no txhais tau hais tias nws yog tsim rau nws qhov kawg qhov ntev hauv kev siv cov yob thaum lub ingot nyob rau ntawm qhov kub siab.

ASTM A992 yog suav tias yog kev hloov pauv rau A36 steel hauv ntau cov ntawv thov kub dov steel.

Cov khoom siv kho tshuab tsis zoo ib yam, txawm tias lawv zoo sib xws. A36 steel muaj qhov tsawg kawg nkaus lub zog ntawm 36ksi thiab qhov kawg tensile lub zog ntawm 58, 000-80, 000 psi. Lub caij no, A992 muaj lub zog tensile tawm los ntawm 50 ksi (tsawg kawg) thiab qhov kawg lub zog ntawm 65 ksi (yam tsawg). Hauv lwm lo lus, A992 muaj qhov yuav tsum tau muaj zog tsawg dua. elongation ntawm kev tawg yog hais txog tib yam, 21% rau tej daim mus txog 2 ntiv tes tuab, tab sis ASTM A36 yog me ntsis ntxiv ductile nyob rau hauv thicker seem (txog 8 ntiv tes) ntawm 20% vs. A992's 18%.
