cev 253m
Khoom Description
Cov tshuaj muaj pes tsawg leeg ntawm 253ma stainless hlau yog sib npaug, ua rau 253ma yeeb nkab muaj qhov ua tau zoo tshaj plaws ntawm 850 degree mus rau 1100 degree qhov kub thiab txias: siab tiv thaiv oxidation, oxidation ntawm daim tawv nqaij kub txog li 1150 degree; Tsis tshua muaj kev sib txawv ntawm qhov muaj peev xwm sib txawv heev. thiab creep rupture lub zog; Nyob rau hauv feem ntau ntawm cov pa nruab nrab muaj zoo tiv thaiv kub corrosion thiab nplai txhuam resistant muaj peev xwm; siab zog yield thiab tensile zog ntawm kub.
253ma yeeb nkab kuj muaj zoo formability thiab weldability, thiab txaus rau machinability. Dhau li ntawm chromium thiab npib tsib xee alloy, 253ma stainless hlau kuj tseem muaj me me ntawm Rare Earth Metals, Rare Earth Metals, REM), txhawm rau txhim kho nws cov oxidation tsis kam.Nitrogen ntxiv los txhim kho cov khoom nkag thiab ua rau qhov no yog cov hlau austenitic. .Txawm hais tias cov ntsiab lus ntawm chromium thiab npib tsib xee yog qhov tsawg, tab sis hom stainless hlau no muaj ntau qhov xwm txheej nrog cov hlau alloyed siab thiab npib tsib xee puag alloy siab kub cov khoom zoo ib yam.

Corrosion Resistance
Txawm hais tias tsis yog tsim los rau aqueous corrosion kuj, lub siab chromium thiab nitrogen cov ntsiab lus muab cov qib pitting tsis kam kwv yees li ntawm 316. 253ma yeeb nkab txawm li cas los xij muaj cov ntsiab lus carbon siab yog li muaj kev cuam tshuam los ntawm kev siv vuam lossis kev pabcuam raug.
Thaum tshav kub kub Resistance
Oxidation - zoo heev tiv taus huab cua, ntawm qhov kub txog li 1150 degree. Nyob rau hauv qhov kub kub, cov hlau sai sai ua ib tug nyias, heev adherent thiab elastic oxide. Qhov no oxide muab kev tiv thaiv zoo txawm tias nyob rau hauv cov xwm txheej cyclic.
Carburisation - Nyob rau hauv cov xwm txheej oxidising qib no tuaj yeem ua tau zoo, tab sis cov alloys nrog cov ntsiab lus ntau dua nickel yog qhov nyiam yog tias cov cua txo qis.
Sulphidation - zoo tiv thaiv sulfur-bearing gases nyob rau hauv ib qho chaw oxidising, txawm tias tsuas muaj cov pa oxygen. Txo cov roj cua tiv thaiv kev tiv thaiv oxide tsim.
253ma stainless hlau muaj lub zog siab ntawm qhov kub siab yog li feem ntau yog siv rau cov qauv thiab cov ntawv thov siab ntawm qhov kub siab tshaj li 500 degree thiab txog li 900 degree. Nws lub zog ntawm qhov kub thiab txias yog siab dua li ntawm lwm yam xws li Qib 310.
253ma yeeb nkab yuav nkag mus rau hauv qhov kub thiab txias ntawm 425-860 degree ; Qhov no tsis yog teeb meem rau kev siv kub, tab sis yuav ua rau txo qis aqueous corrosion kuj.
Kev kho cua sov
Kev Kho Hniav (Annealing) - Kub rau 1050-1150 degree thiab txias sai. Nws raug pom zoo tias cov khoom siv yuav tsum tau kho tom qab 10-20% ua haujlwm txias kom ua tiav qhov siab tshaj plaws creep zog hauv kev pabcuam.
Qib no tsis tuaj yeem hardened los ntawm kev kho cua sov.
