Stellite 3 Yeeb Nkab (UNS R30003)
Stellite 3 Yeeb Nkab (UNS R30003)
Stellite 3 yeeb nkab (UNS R30003) yog siab -carbon, siab-tungsten-cobalt-raws li nyuaj alloy tubing, ib tug neeg sawv cev ntawm cobalt -chromium-tungsten (molybdenum) nyuaj alloys, nrog rau 3 zaug ntawm stellite.
Cov khoom no yog tsim los ntawm precision casting los yog hmoov metallurgy txheej txheem, kom ntseeg tau siab alloy purity, uniform microstructure, thiab ob peb yam tsis xws luag.
Cov ntaub ntawv muaj xws li seamless tubing, welded tubing, thiab precision tubing. Sab nraud txoj kab uas hla, phab ntsa thickness, thiab ntev tuaj yeem ua raws li cov neeg siv khoom xav tau. Kev xa khoom muaj xws li casting, kub extrusion annealing, kos duab txias, los yog kev daws teeb meem. Kev kho deg muaj xws li pickling lossis polishing (Ra tsawg dua lossis sib npaug li 1.6μm).
Cov ntawv thov ib txwm: twj tso kua mis / lub tes tsho, lub rooj zaum valve / cores, burner nozzles, rolling mill guides, bearing bushings, and wear-resistant liners.
Cov lus ceeb toom tseem ceeb: Elongation < 1%, tsim rau qis- cuam tshuam, siab - hnav ib puag ncig. Tsis pom zoo siv rau hauv kev cuam tshuam lossis kev vibration loads.
Cov yam ntxwv tseem ceeb thiab qhov zoo
Exceptional Hnav
Cov ntsiab lus siab carbide ntawm Stellite 3 yeeb nkab yog qhov laj thawj tseem ceeb rau nws cov kev hnav zoo heev. Nyob rau hauv ASTM G65 kev sib tsoo log hnav, nws hnav tus nqi qis dua qhov uas feem ntau siv Stellite 6; nrog nce load thiab ceev, nws hnav tsis kam yog superior rau ntawm Stellite 6 los yog 12.
01
Zoo heev -Qhov kub thiab txias
Cov khoom no tuav zoo heev hardness ntawm qhov kub thiab txias: 606 HV ntawm chav tsev kub, 406 HV ntawm 600 degree, 330 HV ntawm 700 degree, thiab 217 HV ntawm 800 degree. Nws oxidation tsis kam mus txog 1000 degree.
02
Zoo Corrosion Resistance
Nws muaj kev tiv thaiv zoo heev rau ntau yam oxidizing media xws li nitric acid, phosphoric acid, thiab formic acid, thiab tseem tiv taus siab -kub sulfur corrosion. Txawm li cas los xij, nws tsis haum rau ntev - immersion nyob rau hauv muaj zog txo acids (xws li hydrochloric acid).
03
Tsawg coefficient ntawm thermal expansion
Nws coefficient ntawm thermal expansion yog ze rau ntawm cov hlau feem ntau, ua kom yooj yim sib xyaw lossis welded los ua ke.

Kev xaiv thiab kev ua haujlwm
Lus Cim Tseem Ceeb:Stellite 3 muaj qhov elongation tsawg dua 1%, txhais tau hais tias cov khoom yog nkig heev thiab muaj peev xwm tsis tshua muaj kev cuam tshuam los yog kev vibration loads. Thaum xaiv cov khoom siv, xyuas kom meej tias daim ntawv thov ib puag ncig yog ib qho kev cuam tshuam qis thiab hnav siab.
Machining Notes:Vim nws tsis tshua muaj siab hardness, cov pa txiav yuav tsum muaj cov cuab yeej carbide; kev sib tsoo yog txoj kev zoo dua machining. Vim nws cov hardness siab thiab brittleness, nws yog tsis yooj yim sua los tsim ib tug tawg - dawb weld overlay.
