253MA tshav kub-resistant alloy zog
253MA austenitic chromium nickel silicon alloy muaj lub zog zoo heev thiab tsis muaj qhov sib piv thaum tshav kub kub. 253MA tau tsim muaj ntau dua 30 xyoo dhau los thaum kev lag luam xav tau cov cua sov-resistant stainless hlau nrog lub zog siab thiab zoo oxidation tsis kam.
Txawm hais tias muaj tsuas yog 10 npib tsib xee, 253MA alloy muaj lub zog zoo heev thiab muaj zog tiv thaiv oxidation, sulfidation thiab corrosion / hnav tsis kam. Qhov no ua rau 253MA alloy muaj kev lag luam ntau dua li cov khoom siv hluav taws xob feem ntau.
Lub siab kub tsis kam ntawm 253MA yog tau los ntawm kev tswj nruj ntawm micro-alloy additives. Thaum lub creep rupture lub zog muaj txiaj ntsim nyob rau hauv kev sib xyaw ntawm nitrogen, carbon thiab cerium, nws superior oxidation kuj yog tshwm sim los ntawm kev sib xyaw ntawm cerium thiab silicon.
1. Tshuaj muaj pes tsawg leeg ntawm 253MA: Carbon C: 0.05-0.10, Sulfur S: Tsawg dua los yog sib npaug rau 0.030, Silicon Si: 1.40-2. 00, Chromium Cr: 20.00-22.
Nitrogen N: {{0}}.14-0.20, Ce: 0.03-0.08.
fabrication thiab welding
Stainless hlau 253 MA yog ib qho yooj yim los tsim los ntawm cov txheej txheem kev lag luam. Stainless hlau yog tougher thiab yooj yim rau tshuab sai dua carbon steel. Txawm li cas los xij, kev ua haujlwm hardening nyiam ntawm cov hlau no tuaj yeem raug txo kom tsawg nyob rau hauv cov xwm txheej ntawm kev noj zaub mov zoo thiab tsis muaj kev ceev ua ke nrog ntau cov kua dej txiav.
Stainless hlau 253 MA tuaj yeem welded siv cov txheej txheem vuam. Filler hlau yuav tsum muaj qhov sib xws rau qhov siab tshaj plaws weld kev ncaj ncees thiab kev ua tau zoo.
2. Kev ua tau zoo ntawm 253MA: 1. Piv nrog 310S thiab 1Cr20Ni14Si2, nws muaj kev ua tau zoo dua, txuag Ni thiab pheej yig. 2. Nws muaj lub zog siab ntawm 900 degree. Hauv huab cua, nws tuaj yeem siv txog 1150 degree nyob rau hauv cov xwm txheej tsis muaj zog, thiab muaj qhov kub thiab txias oxidation tsis kam. 3. Lub sij hawm luv luv tensile lub zog ntawm txhua qhov kub yog ntau tshaj 20% siab dua li cov hlau tsis zoo tib yam (xws li 304, 310S). 4. Nws muaj qhov kub thiab txias thiab kev ua haujlwm ntev (kev ua haujlwm siab, kev ua haujlwm ntev).
3. Cov qib sib xws ntawm 253MA: German tus qauv: 1.4835, X9CRNISINCE21-11-2, Asmeskas tus qauv: S30815, F45, 253MA.
Scope ntawm kev siv 253MA: dav siv nyob rau hauv sintering khoom, blast furnace khoom, steel melting, furnaces thiab nruam casting khoom, dov mills (cua sov furnaces), kho cua sov furnaces thiab accessories, mineral khoom thiab cement ntau lawm khoom, thiab lwm yam. 253MA steel tau siv nyob rau hauv cov xwm txheej siab txog li 900 degree thiab tsis-siab-kev coj tus kheej qhov kub thiab txias nrog kev ua haujlwm kub txog li 1150 degree.
253MA tuaj yeem siv rau ntau yam kev siv, ntawm no tsuas yog qee qhov piv txwv:
Pyrolysis nkoj
