W. Nr 2.4856 yog dab tsi?
W.Nr. 2.4856 yog cov khoom siv German tsim rau Inconel alloy 625, uas yog siv dav vim nws lub zog siab, ua haujlwm tau zoo, thiab zoo heev corrosion kuj. Nws qhov kub thiab txias ua haujlwm txuas ntxiv los ntawm qhov kub thiab txias mus txog 980℃(1800℃F). Lub zog ntawm alloy 2.4856 yog muab los ntawm cov khoom siv tshuaj ntxiv dag zog ntawm molybdenum thiab niobium ntawm nickel-chromium matrix. Yog li ntawd, nws tsis tas yuav muaj nag lossis daus hardening kev kho mob thiab tuaj yeem ua tiav rau hauv ntau yam khoom siv, nrog rau cov phaj, coils, raj, tuav, thiab xaim.
Cov khoom siv twg yog 2.4856 sib npaug?
Khoom siv 2.4856, ib tug German (Werkstoff) tooj, yog sib npaug rau Alloy 625, kuj paub los ntawm nws UNS tsim N06625, ua rau nws ib tug siab - zog, corrosion- tiv taus nickel-chromium- molybdenum alloy (NiCr22Mo) dav siv nyob rau hauv cov tshuaj marine, NiCr22Mo. kev lag luam.
Puas yog nickel alloy 2.4856 tib yam li Inconel 625?
Yog lawm, nickel alloy 2.4856 thiab Inconel 625 yog tib yam khoom; "2.4856" yog nws cov khoom siv German tus lej (Werkstoff), thaum "Inconel 625" yog lub npe lag luam rau qhov tshwj xeeb nickel no -chromium- molybdenum alloy, uas muaj lub koom haum Numbering System (UNS) npe N06625.

Corrosion kuj:
Vim nws cov nickel siab, chromium, thiab molybdenum cov ntsiab lus, Inconel 625 nthuav tawm cov corrosion kuj zoo heev, ua rau nws ua tau zoo heev nyob rau hauv ib puag ncig hnyav thiab resistant rau pitting, crevice corrosion, thiab chloride stress corrosion cracking. Nws qhov kev tiv thaiv corrosion yog qhov zoo tshaj plaws rau cov tsoos chromium-nickel- molybdenum stainless hlau (1.4571; 1.4539; 1.4404, thiab lwm yam), thiab nws muaj qhov ua tau zoo heev rau intergranular corrosion, yaig, crevice corrosion, thiab kev nyuaj siab corrosion cracking..
Vuam: Cov Alloy 625 yog ib qho yooj yim rau vuam. Cov khoom siv 2.4831 raug pom zoo ua cov hlau muab tub lim, coj mus rau hauv tus account qhov sib thooj weld seam npaj rau nickel alloys.
Forging: Ua ntej forging, cov hlau yuav tsum tau rhuab mus rau qhov tsawg kawg nkaus ntawm 950 ° C mus rau 1150 ° C. Qhov no yuav tsum tau tuav rau 60 feeb ib 100 hli ntawm decisive phab ntsa thickness. Cov txheej txheem forging yuav siv qhov chaw ntawm 1180 ° C mus rau 950 ° C nrog rau huab cua los yog dej txias.
Puas yog 2.4856 nickel-raws li cov hlau nplaum sib nqus?
Tsis yog, 2.4856 (Alloy 625) feem ntau tsis yog -sib nqus, tshwj xeeb tshaj yog nyob rau hauv nws lub xeev annealed (softened), vim nws cov qauv austenitic, ua rau nws haum rau cov ntawv thov tsis muaj kev cuam tshuam sib nqus, xws li hauv marine lossis tshuaj ua haujlwm ib puag ncig uas muaj zog corrosion kuj tseem xav tau.
Qhov txawv ntawm 2.4856 thiab 1.4404 yog dab tsi?
Qhov sib txawv ntawm 2.4856 thiab 1.4404 nyob rau hauv qhov tseeb tias lawv yog cov khoom sib txawv kiag li: 1.4404 (AISI 316L) yog qis- carbon stainless hlau nrog zoo dav dav corrosion kuj; thaum 2.4856 (Inconel 625) yog qhov siab -kev ua tau zoo nickel alloy uas muaj lub zog zoo tshaj plaws thiab kev tiv thaiv corrosion nyob rau hauv qhov siab siab - kub thiab corrosive ib puag ncig (xws li kev ua tshuaj lom neeg). Yog li ntawd, 2.4856 muaj ntau daim ntawv thov tshwj xeeb thiab tseem kim dua.
