ASTM A516 Qib 70 Steel Description
ASTM A516 yog tus qauv kev qhia tshwj xeeb rau kev ua cov hlab ntsha siab (xws li cov roj tso tsheb hlau luam), cov khoom siv hauv cov pa roj carbon steel rau cov kev pab cuam nruab nrab thiab qis qis, nws yuav txhim kho qhov tsis zoo ntawm cov hlau thaum lub sijhawm ua haujlwm vuam.
ASTM A516 specification yog tus qauv Specification rau Pressure Vessel Phaj, Carbon Steel, rau nruab nrab - thiab qis kub kev pab cuam rau daim hlau nrog rau cov kev pab cuam nyob rau hauv welded siab hlab ntsha uas txhim kho notch toughness yog ib qho tseem ceeb. ASTM A516-70 thiab ASME SA516-70 steel phaj cov khoom yog tsim los ntawm carbon-manganese steels thiab ua rau lub siab lub nkoj zoo (PVQ) cov qauv raws li delineated hauv ASTM A20 / ASME SA20.

ASTM A516 Qib 70 Plate Corrosion Resistance
ASTM A516 Gr 70 daim hlauboasts zoo heev corrosion kuj rau ntau yam tshuaj, xws li chlorine, hydrogen sulfide, sulfuric acid, thiab lwm yam hnyav. Ntxiv chromium, molybdenum, thiab npib tsib xee txhim kho nws cov kev tiv thaiv rau pitting thiab crevice corrosion. Lub phaj lub corrosion kuj tseem ceeb heev nyob rau hauv ntau yam lag luam, xws li marine, petrochemical, thiab tshuaj ua.
ASTM A516 Gr 70 Phaj Thaum tshav kub kub kho
Kev kho cua sov ntawmQib 70 daim phiajNws suav nrog cov cua kub ntawm cov hlau phaj rau qhov kub ntawm 900-1100℃thiab txias rau chav tsev kub. Nws yog ib qho tseem ceeb kom tswj tau qhov kub thiab txias thoob plaws hauv cov txheej txheem kom ntseeg tau tias cov khoom sib xws ntawm cov khoom siv. Raws li qhov xav tau, kev kho cua sov tuaj yeem suav nrog cov txheej txheem normalizing, annealing, quenching, thiab tempering txheej txheem. Rau cov kev kho mob no kom ua tau zoo, lawv yuav tsum tau ua tib zoo saib xyuas thiab tswj kom ua tiav qhov kev ua tau zoo tshaj plaws ntawm cov phaj hlau.

ASME SA 516 Gr.70 Phajyog lub siab - zoo carbon steel phaj nrog zoo heev mechanical zog thiab corrosion kuj. Nws cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, kev tiv thaiv corrosion, thiab cov txheej txheem ntau lawm ua rau nws ua tau zoo tshaj - cov khoom siv hauv ntau daim ntawv thov. Phau ntawv qhia no muab kev nkag siab txog cov khoom siv, nws cov khoom, thiab nws cov kev siv. Rau qhov xav tau ntau tshaj plaws nyob rau hauv ib puag ncig thiab kev siv, ASTM A516 Qib 70 phaj yog qhov mus - rau kev xaiv rau cov tuam txhab nrhiav lub zog, kav ntev, thiab tsis kam hnav thiab tsim kua muag.
FAQ
