ASTM, lub npe hu ua American Society for Testing and Materials, yog ib lub koom haum thoob ntiaj teb muaj kev cuam tshuam rau kev tsim thiab tshaj tawm cov qauv rau ntau yam kev lag luam. Cov qauv no muab cov qauv kev sim, kev qhia tshwj xeeb thiab cov txheej txheem rau kev lag luam Asmeskas. Cov qauv no yog tsim los xyuas kom meej qhov zoo, kev ua tau zoo, thiab kev nyab xeeb ntawm cov khoom thiab cov khoom siv thiab pab txhawb kev ua haujlwm zoo ntawm kev lag luam thoob ntiaj teb.
Kev sib txawv thiab kev pab them nqi ntawm ASTM cov qauv yog dav thiab npog ntau yam xws li, tab sis tsis txwv rau, cov ntaub ntawv science, engineering engineering, chemistry, hluav taws xob engineering, thiab mechanical engineering.ASTM cov qauv npog txhua yam los ntawm kev sim thiab tshuaj xyuas cov ntaub ntawv raw. rau cov kev xav tau thiab kev taw qhia thaum tsim khoom, tsim khoom, thiab siv.
ASTM A36 / A36M Cov Lus Qhia:
Cov txheej txheem tshwj xeeb rau steel npog cov kev cai rau cov qauv carbon steel rau kev tsim kho, fabrication, thiab lwm yam kev siv engineering.
A36 Steel PhajTxoj Cai Tswjfwm
Kev ua tiav tus qauv ASTM A36 / A36M-03a, (sib npaug rau ASME code)
A36 plamsiv
Cov qauv no siv rau cov txuas hniav thiab cov tsev uas muaj riveted, bolted thiab welded lug, nrog rau cov hom phiaj dav dav hlau zoo carbon steel seem, daim hlau thiab tuav.A36 steel phaj yield nyob rau hauv txog 240MP, thiab yuav nce nrog cov thickness ntawm cov khoom rau ua kom tus nqi tawm los txo qis, vim muaj cov ntsiab lus ntawm cov pa roj carbon monoxide, qhov kev ua tau zoo tag nrho ntawm qhov zoo dua, lub zog, plasticity thiab vuam thiab lwm yam khoom kom tau zoo dua. match, feem ntau dav siv.
A36 steel phaj tshuaj muaj pes tsawg leeg:
C: ≤ 0.25, Si ≤ 0.40, Mn: ≤ 0.80-1.20, P ≤ 0.04, S: ≤ 0.05, Cu ≥ 0.20 (thaum cov kev cai ntawm cov hlau uas muaj tooj liab).
Mechanical zog:
Yield zog: ≥250.
Tensile zog: 400-550.
Elongation: ≥20.
Lub teb chaws tus qauv thiab A36 cov ntaub ntawv zoo ib yam li Q235.
