253MA Stainless Hlau Seamless Yeeb Nkab
253MA Stainless Hlau Seamless Yeeb Nkab
253MA (UNS S30815) yog npib tsib xee -txuag, tshav kub- tiv taus austenitic stainless hlau tsim los ntawm 21Cr-11Ni qib los ntawm kev sib xyaw nitrogen (N) alloying thiab tsis tshua muaj - ntiaj teb cov khoom cerium (Ce). Nws tau tsim los ua kom muaj kev ua tau zoo tshaj - qhov kub thiab txias thaum txo kev cia siab rau cov npib tsib xee kim, yog li muab cov tshuaj siv nyiaj ntau dua.
Tsim tshwj xeeb rau kev siv siab heev -kub, 253MA sawv cev rau kev ua tiav hauv austenitic stainless hlau thev naus laus zis. Los ntawm kev sib xyaw ua ke tsis tshua muaj - ntiaj teb cov ntsiab lus nrog nitrogen stabilization, cov alloy muab kev ua tau zoo ntawm qhov kub txog li 1150℃(2102℃F). Nws qhov tshwj xeeb muaj pes tsawg leeg ua rau nws yog ib qho khoom siv tsis tseem ceeb rau kev tsim hluav taws xob, kev ua lag luam petrochemical, thiab kev siv tshuab ua hluav taws xob.
Cov txiaj ntsig tseem ceeb ntawm 253MA Seamless Pipes:
01
Zoo heev High -Temperature Strength thiab Creep Resistance
Lub zog ntawm cov khoom siv no yog kwv yees li 20-30% siab dua li ntawm 310S, thiab kwv yees li ob npaug ntawm cov pa 310/309 stainless hlau.
02
Superior Oxidation thiab Carburization Resistance
Cov ntsiab lus siab chromium thiab silicon txhawb kev tsim cov ntom ntom Cr₂O₃-SiO₂-CeO₂ cov txheej txheem oxide nyob rau saum npoo ntawm qhov kub thiab txias, tiv thaiv cov pa roj carbon atom nkag mus thiab sulfidation corrosion hauv carbon- lossis sulfur-bearing.
03
Zoo heev Resistance rau Sigma (σ) Phase Embrittlement
253MA tswj hwm microstructural stability thiab toughness thaum lub sij hawm ntev siab -kub raug, txo qhov kev pheej hmoo ntawm tsis ua hauj lwm los ntawm nag lossis daus ntawm embrittling theem.
04
Zoo weldability thiab workability
Nws muaj qhov txias txias thiab kub formability thiab yog sib xws nrog ntau yam vuam txheej txheem, xws li phau ntawv arc vuam thiab argon arc vuam; ruaj khov weld zoo feem ntau tuaj yeem ua tiav yam tsis tas yuav tsum tau preheating lossis post-weld annealing.

FAQ
Q: Qhov txawv ntawm 253MA thiab 310S yog dab tsi, thiab kuv yuav xaiv li cas?
A: Siab- qhov kub thiab txias: 253MA feem ntau pom muaj zog nkag siab dua thiab tawm lub zog ntau dua 310S ntawm qhov kub siab; yog li ntawd, cov phab ntsa nyias nyias tuaj yeem siv tau rau siab - qhov kub ntawm cov khoom siv los txo qhov hnyav. Oxidation tsis kam: 253MA muaj qhov zoo tshaj plaws oxide nplai adhesion nyob rau hauv cyclic oxidation tej yam kev mob. Tus nqi-kev ua tau zoo: 253MA muaj cov ntsiab lus nickel qis, ua rau feem ntau cov nqi raw khoom qis dua. Cov lus qhia xaiv: Yog tias koj qhov project xav tau siab -kub lub zog thiab tus nqi{11}} ua haujlwm tau zoo, 253MA yog qhov kev xaiv pheej yig dua.
Q: Dab tsi yog qhov tsawg kawg nkaus xaj kom muaj nuj nqis (MOQ), thiab tus nqi suav li cas?
A: MOQ: Tus qauv MOQ yog feem ntau 100 kg; MOQ rau tsis yog - tus qauv specifications yuav siab dua. Nqe: Tus nqi kawg yog nyob ntawm tus nqi raw khoom (nickel, chromium, thiab lwm yam), txoj kab uas hla, phab ntsa thickness, ntev, thiab txiav txim kom muaj nuj nqis. Peb pom zoo kom muab cov lus qhia tshwj xeeb kom tau txais cov lus hais tiag - lub sijhawm.
