Cov khoom ntawm 825 yeeb nkab yog dab tsi?
825 alloy nickel yeeb nkab
UNS N08825/W.NR. 2.4858 ib
Cov npe lag luam: Incoloy 825, Inc825, Sanicro 41
Alloy 825 yog npib tsib xee-chromium-hlau solid-solution alloy nrog cov tshuaj nominal muaj pes tsawg leeg ntawm 42% npib tsib xee, 21% chromium, thiab 22% hlau, nrog ntxiv ntxiv ntawm molybdenum, titanium, thiab tooj liab. Nws yog feem ntau paub los ntawm lub npe lag luam Incoloy 825 thiab lub npe UNS N08825.

Corrosion duab
Corrosion kuj
Alloy 825 muaj corrosion kuj zoo nyob rau hauv ntau qhov chaw, xws li txo thiab oxidizing acids, organic acids, seawater, ntsev thiab alkalis. Nws yog tshwj xeeb resistant rau sulfuric acid thiab phosphoric acid. Qhov sib ntxiv ntawm molybdenum muab Alloy 825 zoo tiv thaiv rau hauv cheeb tsam corrosion tshwm sim los ntawm chlorides, nrog rau pitting, crevice corrosion thiab kev nyuaj siab corrosion cracking. Tsis tas li ntawd, 825 alloy kuj muaj oxidation zoo.
Ua haujlwm kub
Ua haujlwm kub
Alloy 825 tuaj yeem siv rau qhov kub thiab txias li 1000 degree F (540 degree). Kev siv Alloy 825 ntawm qhov kub siab tshaj 1000 degree F (538 degree) tsis pom zoo vim yog qhov tsim ntawm cov txheej txheem deleterious uas cuam tshuam tsis zoo rau qhov hnyav thiab ductility.
Mechanical cwj pwm
Mechanical cwj pwm
Alloy 825 muaj nyob rau hauv cov mob annealed los yog ntxiv dag zog los ntawm cov txheej txheem Pilger. Alloy 825 khaws cov khoom siv kho kom zoo ntawm qhov kub txog li 1000 degree F (538 degree) thiab khaws cov tawv tawv zoo ntawm qhov kub thiab txias.
Thaum tshav kub kub kev kho mob cim
Kev kho cua sov
Alloy 825 tsis tuaj yeem muaj zog los ntawm kev kho cua sov. Rau cov ntawv thov kub los yog qhov chaw uas cov khoom yuav tsum tau welded, ib tug stabilization anneal nyob ib ncig ntawm 1725 degree F (940 degree) yog pom zoo. Ntawm qhov kub no, cov pa roj carbon yog khi li titanium carbide. Qhov no tiv thaiv chromium carbide nag lossis daus (xws li rhiab heev) los ntawm qhov tshwm sim ntawm cov ciam teb thaum siv lossis vuam. Rau qhov zoo tshaj plaws toughness thiab ductility, siab dua kub annealing tuaj yeem ua tau.
Kev ua tau zoo
Ua haujlwm tau
Alloy 825 yog tsim rau ob qho tib si kub thiab txias ua haujlwm.
Cov chaw thov
Alloy 825 yog siv dav hauv kev siv roj thiab roj. Lwm yam kev siv suav nrog cov khoom siv tshuaj lom neeg, cov tshuab tso pa tawm thiab lub zog tsim hluav taws xob. CRA muab tshwj xeeb alloy 825 seamless tubing rau ntau yam kev lag luam thiab kev siv, suav nrog:
Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob thiab Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob
