Dab tsi yog ASTM qauv thiab 336 yog dab tsi?

ASTM, lub npe hu ua Asmeskas haiv neeg rau kev sim thiab cov ntaub ntawv thoob ntiaj teb ua rau kev txhim kho thiab kev tshaj tawm ntawm cov qauv rau ntau yam kev lag luam. Cov qauv no muab cov qauv kev sim sib txawv ntawm cov qauv, cov lus qhia thiab cov lus qhia rau Asmeskas kev lag luam. Cov qauv no tau tsim los txhawm rau kom muaj kev ua tau zoo, ua tau zoo, thiab cov khoom lag luam thiab cov khoom lag luam thiab cov khoom lag luam kom nruj ntawm kev lag luam thoob ntiaj teb.

Cov kev sib txawv thiab kev pov hwm ntawm ASTM cov qauv muaj ntau thiab tsis txwv, cov qauv siv hluav taws xob, cov qauv siv hluav taws xob npog txhua yam los ntawm kev sim thiab tshuaj xyuas cov khoom siv raw Txhawm rau kom cov kev cai thiab kev coj qhia thaum lub sijhawm tsim cov khoom tsim, ntau lawm, thiab siv.

ASTM A36 / A36M:

Txheem Qhov kev qhia tshwj xeeb rau cov hlau npog qhov yuav tsum muaj rau cov txheej txheem carbon hlau rau kev tsim kho, kev tsim khoom, thiab lwm yam kev thov engineering.

A36 Hlau PhajCov Qauv Txheej Txheem
Kev ua tiav cov qauv ATM A36 / A36M-03A, (sib npaug rau ASME code)

A36 Phajkev siv
Cov qauv no siv rau choj thiab vaj tse nrog riveted, bolted thiab welded qauv steel zoo, thiab yuav nce nrog cov tuab ntawm cov khoom rau ua cov nqi tawm los txo, vim muaj cov ntsiab lus carbon ntau, lub zog ntawm qhov zoo dua, lub zog, yas thiab lwm yam khoom kom tau txais kev sib tw zoo, feem ntau dav siv.

A36 Steel Phaj Tshuaj Muaj Zog:
C: ≤ 0.25, SI ≤ 0.40, MN: ≤ 0.6-1.20, x 1 0.20 (thaum cov kev cai ntawm tooj liab uas muaj hlau).

Cov Khoom Siv Neeg Kho Tshuab:
Peple zog: ≥250.
Tensile lub zog: 400-550.
Elongation: ≥20.
Cov qauv hauv tebchaws thiab A36 cov khoom zoo ib yam li Q235.
