ASTM A516 Gr.70 yog cov khoom siv carbon steel. Cov pa roj carbon steel yog ib chav kawm ntawm cov ntaub ntawv hlau uas muaj cov pa roj carbon ua lub ntsiab alloying, feem ntau muaj qhov zoo weldability thiab yog li feem ntau haum rau welded manufacturing.
ASTM A516 Gr.70 muaj cov ntsiab lus ntawm cov pa roj carbon monoxide uas ua rau nws ua tau zoo nyob rau hauv qhov kub thiab txias. Cov khoom siv no feem ntau yog siv rau hauv kev tsim cov hlab ntsha siab, boilers, kub exchangers thiab lwm yam khoom uas yuav tsum tau tiv thaiv kev kub siab thiab kub los yog kub ib puag ncig.
ASTM A516 Gr.70 yog tus qauv kev qhia tshwj xeeb rau kev piav qhia cov khoom siv thiab cov khoom siv cuab yeej cuab tam rau cov hlau tsis tshua muaj siab thiab kub siab. Qhov kev qhia tshwj xeeb no tau tsim los ntawm American Society for Testing and Materials (ASTM) thiab tau siv dav hauv ntau hom kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev lag luam roj, roj, tshuaj, hluav taws xob, thiab hluav taws xob nuclear.
Khoom siv:
ASTM A516 Gr.70 yog cov pa roj carbon steel nrog zoo weldability. Nws yog feem ntau siv rau hauv kev tsim cov hlab ntsha siab thiab tsis tshua muaj siab rau khaws cia cov pa roj lossis kua dej.
Mechanical cwj pwm:
Cov khoom siv kho tshuab kev ua tau zoo suav nrog lub zog tensile, lub zog tawm los, thiab elongation, thiab lwm yam. ASTM A516 Gr.70 feem ntau muaj lub zog tensile siab thiab lub zog tawm los, uas ua rau nws tsim nyog rau kev siv siab.
Qhov kub thiab txias:
Nws tuaj yeem ua haujlwm hauv qhov kub thiab txias, yog li nws tsim nyog rau ntau yam kev siv nrog qhov sib txawv ntawm qhov kub thiab txias.
Standard specification:
Kev tsim khoom thiab kev sim ntawm ASTM A516 Gr.70 ua raws li ASTM A516 / A516M tus qauv, uas qhia txog cov tshuaj muaj pes tsawg leeg ntawm cov ntaub ntawv, cov txheej txheem kev ntsuas kev ua tau zoo, thiab cov kev xav tau rau hardness, cuam tshuam, thiab lwm yam.
Daim ntawv thov teb:
ASTM A516 Gr.70 feem ntau yog siv rau hauv kev tsim cov khoom siv rau cov boilers, cov hlab ntsha siab, cov khoom siv hluav taws xob, cov kav dej, thiab lwm cov tshuab ua haujlwm siab. Cov ntawv thov no xav tau cov ntaub ntawv uas tuaj yeem tiv taus qhov kub thiab txias ib puag ncig thaum tswj kev ntseeg tau thiab kev nyab xeeb ntawm cov khoom.
Hauv cov ntsiab lus, ASTM A516 Gr.70 yog cov khoom siv dav siv hauv cov hlab ntsha uas muaj cov khoom siv zoo thiab cov yam ntxwv ntawm qhov kub thiab txias tsis kam, thiab tsim nyog rau kev siv hauv ntau yam kev lag luam. Thaum siv, cov qauv tsim thiab kev teeb tsa tsim nyog yuav tsum tau ua raws li kom ntseeg tau tias kev nyab xeeb thiab kev ua haujlwm ntawm cov hlab ntsha ua tau raws li qhov yuav tsum tau ua.
