Khoom Description
A516 Gr. 70 yog cov pa roj carbon steel phaj dav siv nyob rau hauv qis -kub siab cov hlab ntsha thiab ua raws li tus qauv ASTM A516 / A516M. ASTM A516 Gr. 70 tshuaj muaj pes tsawg leeg yuav tsum ua tau raws li qhov yuav tsum tau teev tseg hauv tus qauv no.
ASTM A516 Gr. 70 feem ntau yog siv rau hauv kev tsim cov pa roj carbon steel phaj rau siab - kub thiab siab - cov hlab ntsha, boilers, thiab lwm yam khoom siv siab. Tus qauv ua kom ntseeg tau tias cov khoom siv tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab lwm yam kev ua tau zoo raws li cov kev xav tau nruj, muab kev nyab xeeb thiab kev ntseeg siab hauv qhov xav tau ib puag ncig. Peb lub tuam txhab muab cov ntawv hlau uas ua raws li ASTM A516 Gr. 70 tus qauv. Thov koj xav tiv tauj peb kom paub meej cov khoom lag luam thiab tus nqi.

Cov yam ntxwv ntawm cov khoom
Cov tshuaj muaj pes tsawg leeg ntawm ASTM A516 Gr. 70 muab nws cov yam ntxwv hauv qab no:
Siab zog
Qhov tsim nyog piv ntawm carbon thiab manganese ntsiab ua rau cov hlau phaj muaj lub zog siab. Cov pa roj carbon zoo nce lub zog thiab hardness ntawm cov hlau, thaum manganese ntxiv dag zog rau ferrite thiab nce lub zog thiab toughness ntawm hlau. Ob leeg ua ke, kom ASTM A516 Gr 70 steel phaj tuaj yeem tiv taus siab dua thiab thauj khoom.
Zoo toughness
Lub phaj steel tuav zoo toughness ntawm qis mus rau nruab nrab kub. Lub caij silicon pab txhim kho lub toughness thiab qaug zog tsis kam ntawm cov hlau. Tsis tas li ntawd, cov ntsiab lus ntawm cov ntawv xov xwm yuav tsum tau tswj xyuas nruj me ntsis thaum lub sij hawm tsim khoom kom txo tau qhov tsis zoo ntawm cov khoom tsis zoo ntawm cov hlau tsis zoo.
Kev ua haujlwm vuam zoo
Cov pa roj carbon sib npaug yog qis, feem ntau tsis ntau tshaj 0.47%, uas ua rau cov hlau phaj muaj kev ua haujlwm zoo vuam. Nyob rau hauv cov txheej txheem vuam, tsis yooj yim los tsim cov kab nrib pleb thiab lwm yam tsis xws luag, yooj yim rau txheej txheem thiab tsim ntau yam complex welded structural Cheebtsam.
Zoo corrosion kuj
Txawm hais tias ASTM A516 Gr 70 steel phaj feem ntau yog carbon steel, tab sis ntxiv me me ntawm tooj liab, npib tsib xee thiab lwm yam khoom, rau qee yam, txhawm rau txhim kho corrosion ntawm cov hlau phaj. Yog li ntawd nws yuav siv tau nyob rau hauv ib co corrosive ib puag ncig, ncua kev pab cuam lub neej ntawm cov khoom.
