Alloy 625 / UNS N06625 / W.NR. 2.4856 ib

Kev piav qhia

Alloy 625 yog npib tsib xee-chromium-molybdenum alloy uas yog siv rau nws lub zog siab, siab toughness thiab zoo heev corrosion kuj. Lub zog ntawm alloy 625 yog muab los ntawm cov nyhuv stiffening ntawm molybdenum thiab niobium ntawm nws cov nickel-chromium matrix. Txawm hais tias cov alloy tau tsim los rau qhov kub thiab txias, nws cov alloyed muaj pes tsawg leeg kuj muab cov theem tseem ceeb ntawm kev tiv thaiv corrosion.

Kev lag luam thiab kev siv

Alloy 625 yog siv nyob rau hauv ntau yam kev lag luam, xws li tsheb, marine, aerospace, roj thiab roj, tshuaj ua thiab nuclear. Cov ntawv siv kawg nkaus suav nrog cov khoom siv hluav taws xob sib hloov, lub hauv siab, cov pob qij txha nthuav dav, cov tshuab tso pa tawm, cov fasteners, ceev txuas fittings thiab ntau lwm yam kev siv uas yuav tsum tau muaj zog thiab tsis kam tiv thaiv ib puag ncig corrosive.

Kev tiv thaiv corrosion

Alloy 625 muaj kev tiv thaiv zoo rau oxidation thiab scaling ntawm qhov kub thiab txias. Ntawm 1800 ° F, scaling resistance ua ib qho tseem ceeb hauv kev pabcuam. Nws yog superior rau ntau lwm yam kub alloys nyob rau hauv cyclic cua sov thiab txias tej yam kev mob. Kev sib xyaw ua ke ntawm cov ntsiab lus alloyed hauv alloy 625 ua rau nws tuaj yeem tiv taus ntau yam kev sib kis hnyav. Yuav luag tsis muaj kev tawm tsam hauv ib puag ncig me me, xws li dej tshiab thiab dej hiav txwv, nruab nrab pH ib puag ncig, thiab alkaline xov xwm. Cov ntsiab lus chromium ntawm cov hlau no ua rau muaj kev tiv thaiv zoo tshaj rau oxidizing ib puag ncig. Cov ntsiab lus siab molybdenum ua rau alloy 625 heev tiv taus pitting thiab crevice corrosion.

Fabrication thiab Thaum tshav kub kub kho

Alloy 625 tuaj yeem tsim siv ntau yam kev ua haujlwm txias thiab kub. Alloy 625 resists deformation ntawm kub ua hauj lwm kub, yog li ntawd yuav tsum tau ntau dua loads los tsim cov khoom. Kev tsim kub yuav tsum tau ua nyob rau hauv qhov kub ntawm 1700 ° txog 2150 ° F. Thaum lub sij hawm ua hauj lwm txias, cov khoom ua hauj lwm hardens sai dua li ib txwm austenitic stainless hlau. Alloy 625 muaj peb qhov kev kho cua sov: 1) kev daws teeb meem ntawm 2000/2200 ° F thiab cua quench lossis nrawm dua, 2) annealing 1600/1900 ° F thiab cua quenching lossis nrawm dua thiab 3) kev ntxhov siab ntawm 1100/1500 ° F thiab cua quenching . Cov tshuaj annealed (qib 2) cov khoom siv feem ntau yog siv rau cov ntawv thov siab dua 1500 ° F qhov kev tiv thaiv kev nkag yog qhov tseem ceeb. Cov ntaub ntawv mos-annealed (qib 1) feem ntau yog siv rau qhov kub thiab txias thiab muaj qhov zoo tshaj plaws ntawm tensile thiab rupture zog.
