ASTM A709 yog tus qauv kev qhia tshwj xeeb rau daim hlau, tuav, thiab cov duab siv rau cov qauv hlau txuas hniav thiab siv rau Carbon HSLA (High Strength Low Alloy), Q&T (Quench & Tempered), thiab stainless- steel hlau. ASTM A709 qib 36,50,70, thiab 100 suav nrog cov npe rau kev txhim kho atmospheric corrosion resistance (W). Cov qauv no yog raws li American Association of State Highway and Transportation Officials (AASHTO) cov kev cai rau cov khoom nro hauv cov choj. GNEE nqa cov khoom lag luam zoo ntawm ASTM A709 qib 50 cov khoom siv uas feem ntau siv hauv cov tsev siab - nce siab, txuas hniav, roj rigs, cua ua liaj ua teb, thiab txhua qhov chaw muaj zog dua, kev ua haujlwm zoo, thiab qhov zoo tshaj plaws corrosion kuj yuav tsum tau.

ASTM A709 Qib 50 yog dab tsi?
General Product Description. ASTM A709 yog tus qauv tshwj xeeb rau Cov Hlau Hlau rau Cov Txuas Txuas thiab suav nrog cov pa roj carbon, siab -lub zog qis- alloy, thiab quenched thiab tempered alloy steels siv los ua cov phiaj xwm hauv kev tsim cov choj.
Qib 50 steel yog dab tsi?
Qib 50 steel yog siab - lub zog qis alloy steel nrog qhov tsawg kawg nkaus lub zog ntawm 50 ksi thiab lub zog tensile yam tsawg kawg nkaus ntawm 65 ksi. Qib 50 muaj cov ntsiab lus alloying ntau dua li cov pa roj carbon monoxide thiab muaj kev tiv thaiv ntau dua rau atmospheric corrosion.
GNEE tau ua haujlwm rau cov neeg siv khoom hauv ntau dua 50 lub teb chaws (North America, Europe, Southeast Asia, Middle East, thiab lwm yam) thiab tau txais kev nplua nuj nyob rau hauv cov nqe lus lag luam thoob ntiaj teb (FOB, CIF, EXW) thiab cov khoom lag luam hauv zos. Peb cov kev sib txuas lus tau zoo (Lus Askiv, Mev, Arabic kev txhawb nqa) thiab cov txheej txheem kev lag luam pob tshab ua rau kev sib koom tes zoo thiab tsis muaj teeb meem - dawb.
