Khoom Description
A516Gr70 yog lub siab -lub zog, qis- alloy steel phaj rau boiler siab hlab ntsha, cais raws li American Society for Testing and Materials (ASTM) standard grade. A516Gr70 qhia tias cov hlau no muaj qib tensile zog ntawm 70 ksi (kwv yees li 483 MPa). Cov phaj hlau no feem ntau yog siv rau kev tsim khoom ntawm siab-siab, siab{11}}kub, thiab siab{12}}cov cuab yeej siv ceev ceev, xws li turbine blades, siab - cov hlab ntsha, thiab li qub.
A516Gr60 yog lub siab -kev ua tau zoo carbon steel phaj tshwj xeeb tsim los rau kev tsim khoom nruab nrab- thiab qis-kub siab cov hlab ntsha. Cov phaj hlau no ua raws li ASTM cov qauv thiab ua raws li ASME tshwj xeeb cov txheej txheem. Nws yog qhov tsim nyog rau cov ntawv thov siab xws li cov chaw cia khoom, cov khoom siv hluav taws xob tsawg -siab boilers, thiab cov khoom siv hluav taws xob.
Yuxin Steel tuaj yeem muab koj cov ntawv hlau ntawm ntau qib thiab cov lus qhia tshwj xeeb. Yog tias koj xav paub ntau ntxiv txog cov ntaub ntawv khoom thiab tus nqi, thov xa email rau peb.info@chinasteelcompany.comPeb tos ntsoov yuav hnov los ntawm koj!

A516GR70 vs A516GR60
Mechanical Properties:
Lub zog tawm los thiab lub zog tensile ntawm A516GR70 yog ob qho tib si siab dua li ntawm A516GR60. Yog li ntawd, A516GR70 steel daim hlau muaj zog dua thiab nruj, ua rau lawv tiv taus siab dua thiab thauj khoom.
Tshuaj muaj pes tsawg leeg:
Cov ntsiab lus ntawm manganese txawv ntawm ob qib. Qhov tsawg kawg nkaus manganese cov ntsiab lus ntawm A516GR70 yog siab dua li ntawm A516GR60. Qhov no pab txhim kho lub zog thiab tawv ntawm A516GR70.
Kev kho cua sov yuav tsum muaj:
Rau cov hlau phaj tuab dua 40 hli, A516GR70 feem ntau xav tau kev kho kom zoo. Qhov no ua rau kom zoo dua microstructure thiab kev ua tau zoo. A516GR60 yuav tsis xav kom normalising, nyob ntawm seb cov ntawv thov tshwj xeeb thiab cov neeg siv khoom xav tau.
Corrosion Resistance:
A516GR70 qhia tau hais tias zoo dua corrosion kuj piv rau A516GR60, tshwj xeeb tshaj yog nyob rau hauv corrosive ib puag ncig uas muaj hydrogen sulphide, ua kom nws haum rau siv nyob rau hauv hnyav corrosive tej yam kev mob.
Kev siv thaj chaw:
A516GR70, nrog nws lub zog siab dua thiab zoo dua corrosion kuj, feem ntau yog siv rau hauv cov ntawv thov nrog cov khoom siv nruj dua, xws li siab - siab, siab - corrosion- kev pheej hmoo siab ntawm cov hlab ntsha.
A516GR60 yog siv rau hauv cov khoom siv lub nkoj siab zoo tib yam uas yuav tsum muaj lub zog thiab kev tiv thaiv corrosion kuj qis dua.
