Vuam thiab kev kho cua sov
10CrMo9-10 muaj weldability zoo, tab sis cov chromium-molybdenum chemistry txhais tau tias vuam yuav tsum ua raws li tus txheej txheem tswj. Preheating ntawm 200 - 300 C thiab tom qab-weld kev kho cua sov ntawm 650 - 700 C feem ntau yuav tsum tau ua kom tsis txhob txias tawg thiab txo qhov kev ntxhov siab. Kev sib txuam lossis qis- alloy muab tub lim hlau nrog cov chromium zoo sib xws- cov ntsiab lus molybdenum yog siv, thiab cov weld tiav yuav tsum tau kuaj xyuas los ntawm kev sim hardness lossis lwm yam NDT. Cov khoom siv tsis yog stainless hlau: qhov twg ntub corrosion los yog hnyav oxidation yuav tsum, yuav tsum tau xav txog qib siab dua-alloy xws li 9Cr lossis austenitic stainless hlau.

FAQ
Puas yog 10CrMo9-10 zoo ib yam li ASTM A335 P22?
Yog, rau lub hom phiaj siv. Ob leeg yog 2.25Cr-1Mo qis- alloy steels siv nyob rau hauv high-temperature siab. P22 yeeb nkab yog ASTM A335 tsim, thaum 10CrMo9-10 yog EN 10216-2 kev tsim nrog tib lub npe nominal.
Lub npe 10CrMo9-10 txhais li cas?
Cov lej qhia cov ntsiab lus nruab nrab ntawm cov alloy: 10 yog 0.10 feem pua carbon, 9 faib los ntawm 4 muab 2.25 feem pua chromium, thiab 10 faib los ntawm 10 muab 1.0 feem pua molybdenum.
Qhov kev pabcuam siab tshaj plaws rau 10CrMo9-10 yog dab tsi?
Rau ntev -lub sij hawm creep kev pab cuam qib feem ntau yog siv txog li 580 C. Saum toj no ntau yam, oxidation thiab creep zog tsis tau guaranteed thiab siab dua - qib alloy yuav tsum tau.
Puas yog 10CrMo9-10 xav tau kev kho cua sov tom qab vuam?
Hauv ntau daim ntawv thov code, yog. Preheating ntawm 200 - 300 C thiab PWHT ntawm 650 - 700 C feem ntau yuav tsum tau ua kom tsis txhob muaj qhov txias txias thiab kom rov ua kom tawv nqaij hauv qhov cua sov- thaj tsam cuam tshuam.
Puas yog 10CrMo9-10 stainless hlau?
Tsis yog. Nws yog ib qho qis- alloy tshav kub-resistant steel. Nws tiv taus oxidation zoo dua li cov pa roj carbon monoxide, tab sis muaj kev txwv tsis pub ua rau ntub corrosion, yog li nws yuav tsum tsis txhob raug xaiv rau corrosive media yam tsis muaj coatings los yog ntau dua -alloy lwm txoj.
Daim ntawv pov thawj dab tsi yuav tsum tau thov nrog 10CrMo9-10 yeeb nkab?
Daim ntawv pov thawj EN 10204 3.1 zeb xeem yog tus qauv yuav tsum tau muaj, thiab 3.2 nrog thib peb - tog neeg tim khawv yog siv rau lub zog tseem ceeb lossis cov khoom siv siab.
