Tsis tas li ntawd, lawv cov khoom tiv thaiv corrosion zoo tshaj plaws ua rau lawv zoo tagnrho rau kev siv nyob rau hauv ib puag ncig uas muaj ya raws los yog ntsev huab cua, xws li marine atmospheric tej yam kev mob. Lawv muaj lub zog nkag tau zoo heev ntawm qhov kub siab thiab qib toughness zoo txawm tias qhov kub qis dua -200℃(-330℃F). Thaum kawg, cov phiaj no tau yooj yim weldable los ntawm kev ua raws li cov txheej txheem ib txwm ua, ua rau muaj kev sib koom ua ke ntawm cov khoom siv thiab muab tub lim hlau yam tsis tas yuav tsum tau preheat ua ntej vuam ua haujlwm.

Yooj yim rau Fabricate:

SA 387 Gr 11 daim hlau yog ib qho yooj yim rau fabricate, uas ua rau lawv ib tug nrov kev xaiv ntawm manufacturers. Cov phaj tuaj yeem txiav tau yooj yim, drilled, thiab welded kom haum raws li qhov yuav tsum tau ua. Qhov no txhais tau tias cov tuam txhab siv tau cov phiaj no los tsim cov hlab ntsha ntawm cov duab sib txawv thiab ntau thiab tsawg.

Tus nqi -zoo:

SA 387 Gr 11 daim hlau yog tus nqi - muaj txiaj ntsig zoo hauv kev tsim cov hlab ntsha siab. Cov phaj no paub txog lawv qhov ua tau ntev, txhais tau tias lawv tuaj yeem muaj sia nyob ntev dua nyob rau hauv siab -siab, txo qhov xav tau kev saib xyuas tsis tu ncua. Qhov no, nyob rau hauv lem, txo cov nqi txuam nrog kev tu thiab kho.

Dav Muaj:

SA 387 Gr 11 daim hlau muaj dav hauv khw. Qhov no txhais tau tias cov tuam txhab lag luam tuaj yeem yooj yim muab cov phiaj no los ntawm cov neeg muag khoom. Qhov no ua rau nws yooj yim dua rau cov tuam txhab ua kom tiav lawv cov haujlwm raws sij hawm thiab nyob rau hauv pob nyiaj siv.

Hauv kev xaus, SA 387 Gr 11 daim hlau muaj ntau yam zoo hauv kev tsim cov hlab ntsha siab. Cov phaj no paub txog lawv cov khoom muaj zog - zog, corrosion resistance, yooj yim ntawm fabrication, nqi-effectiveness, thiab dav muaj. Tag nrho cov txiaj ntsig no ua rau SA 387 Gr 11 daim hlau yog qhov kev xaiv nrov rau cov tuam txhab nrhiav kom tsim tau siab - cov hlab ntsha zoo uas tuaj yeem tiv taus qhov hnyav tshaj plaws.

Yog tias koj xav yuav SA 387 Gr 11 daim hlau, muab lawv los ntawm tus neeg muag khoom txhim khu kev qha kom ntseeg tau tias koj tau txais cov phiaj xwm zoo tshaj plaws uas ua tau raws li koj xav tau.
