DIN 17175 13CrMo44 Seamless Steel Pipes piav qhia
13CrMo44 yog chromium-molybdenum alloy steel yeeb nkab rau boilers thiab cov hlab ntsha siab, ua raws li cov kev qhia tshwj xeeb ntawm DIN17175.
Cov yeeb nkab steel hlau no tsis yog tsuas yog nthuav tawm cov tawv tawv heev thiab lub zog tab sis kuj muaj qee yam hnav tsis kam, qaug zog tiv thaiv, corrosion tsis kam, cuam tshuam tsis kam, nrog rau kev ua haujlwm zoo thiab tsim tau.
13CrMo44 feem ntau yog siv rau hauv cov hlab ntsha siab thiab cov khoom siv petrochemical, xws li petrochemical khoom tsim, roj refining, boiler khoom manufacturing, siab hlab ntsha manufacturing, nuclear fais fab nroj tsuag, thiab cov khoom tsim hluav taws xob.

Kev kho cua sov rau 13CrMo44 feem ntau yognormalizing + tempering.
normalizing: Cua sov li ntawm 900-960 degree, tuav, thiab ces cua txias. Lub hom phiaj yog los kho cov nplej thiab homogenize microstructure.
Tempering: Ua tom qab normalizing, nrog tempering kub feem ntau nyob rau hauv qhov ntau ntawm620-680 degree. Lub hom phiaj yog txhawm rau txo cov kev ntxhov siab sab hauv, txhim kho toughness thiab ductility, thiab ua tiav cov khoom siv txhua yam uas xav tau.
Cov khoom kawg (tshwj xeeb tshaj yog lub zog thiab toughness) nyob ntawm qhov tshwj xeeb normalizing thiab tempering txheej txheem tsis.
