Lo lus nug 1: Cov ASTTM A335 P9 cov yeeb nkab tsim?
ASTM A335 P9 cov yeeb nkab steel yog feem ntau yog tsim siv cov yeeb nkab uas siv cov yeeb nkab ntau lawm, ua rau muaj cov duab txias lossis txias. Cov khoom siv raw yog melted, nrum, thiab kub-}}}}}}} Khib mus rau hauv cov yeeb nkab. Mob khaub thuas yog siv los txhim kho qhov tseeb thiab qhov tseeb. Kev kho cua sov (xws li normaling thiab tempering) yog ib kauj ruam tseem ceeb kom ntseeg tau cov neeg kho tshuab. Cov khoom kawg ntawm kev soj ntsuam nyuaj thiab kuaj.
Lo lus nug 2: Kev kho kom sov puas cuam tshuam li cas cov khoom ntawm Astm A335 P9 steel yeeb nkab?
Kev kho cua sov (xws li normaling thiab tempering) kho cov qauv nplej ntawm P9 qauv ntawm P9 steel thiab txhim kho nws lub zog thiab tawv. Li cas los hloov cov mov ntais loj los ntawm cov cua sov saum toj no qhov kub tob tob thiab cua txias. Tempering txo kev ntxhov siab sab hauv thiab txhim kho cov khoom siv ductility. P9 steel yeeb nkab uas tsis tau kho tshav kub yuav tsis tau raws li cov neeg siv khoom xav tau. Yog li ntawd, kev kho cua sov yog ib qho tseem ceeb ntawm nws cov txheej txheem ntau lawm.
Lo lus nug 3: Cov Qauv Tsim Ntau Lawm rau ASTM A335 P9 Steel Yeeb Nkab?
ASTM A335 P9 steel yeeb yuav tsum tsim raws li Astm A335 / A335 / A335m, npog cov khoom siv tshuaj, thiab muaj kev puas tsuaj rau txhua yam. Tsis tas li ntawd, ASME SA335 tau raug hais kom ntseeg tau tias siv cov khoom siv siab. Lwm cov qauv uas muaj feem xyuam suav nrog ASTM A450 (cov kev cai dav dav) thiab ASTM E213 (kev sim ua tsis tau). Cov qauv no kom ua tau zoo thiab ntseeg tau ntawm cov yeeb nkab steel.
Lo lus nug 4: Tus txheej txheem kub kub thiab kub npaum li cas cuam tshuam rau kev ua tau zoo ntawm P9 steel yeeb nkab?
Kub Rolling muaj kev ua haujlwm siab thiab tus nqi qis, tab sis nrog cov khoom tsis zoo. COOGR CAV muab ntau qhov ntev dua thiab cov smoother nto, tab sis ntawm tus nqi siab dua. Txias - Cov yeeb nkab txuas nrog cov khoom siv zoo dua li kub tshaj}}} Rolled yeeb nkab vim muaj kev ua haujlwm hnyav dua. Kev xaiv ntawm cov txheej txheem yog nyob ntawm cov ntaub ntawv uas muaj cov ntaub ntawv tshwj xeeb.
Lo lus nug 5: Dab tsi yog cov txheej txheem kho deg ua ke rau ASTM A335 P9 steel yeeb nkab? Cov txheej txheem kev kho deg ua ke suav nrog Sandblasting, Pickling, thiab roj txhawm rau txhim kho corrosion tsis kam thiab zoo nkauj. Sandblasting tshem tawm nplai thiab nce nto roughness, kho txheej txheej nplaum. Pickling tshem tawm saum npoo impurities nrog tshuaj lom neeg. Roj ranking muab cov luv - nws tsis muaj xeb tiv thaiv. Rau ntev - Term corrosion tiv thaiv, galvanizing los yog txau nrog high {{10} {resualant txheej tuaj yeem siv tau.
