Zoo heev Hardness thiab hnav tsis kam
Stellite 6 daim ntawv M₇C₃- hom carbides sib npaug faib nyob rau hauv cobalt -raws li cov kua matrix. Nws cov hardness ib txwm nyob ntawm HRC 35-45 (kwv yees HV 380-450) nyob rau hauv cam khwb cia lossis overlay-welded tej yam kev mob. Muab piv rau cov qib siab carbon (xws li Stellite 1, 4), nws muaj cov hardness nruab nrab nrog superior toughness, zoo tiv taus abrasive, nplaum, thiab erosive hnav. Nws yog tshwj xeeb tshaj yog haum rau zawv zawg kev sib txhuam tej yam kev mob raug rau nruab nrab tej yam kev mob.
Zoo Siab -Tub kub Liab Hardness thiab Oxidation Resistance
Stellite 6 khaws cia kwv yees li 30 HRC hardness ntawm 600℃thiab txog 25 HRC txog 760℃(1400℃F). Cov ntsiab lus siab chromium txhawb kev tsim cov Cr₂O₃ oxide zaj duab xis rau saum npoo. Tom qab raug huab cua ntawm 800℃rau 1000 teev, oxidation hnyav nce tsawg dua 1 mg / cm², deb tshaj qhov oxidation tsis kam ntawm cov cuab yeej zoo tib yam steels thiab hlau-raws li hnav- cov alloys resistant. Qhov no ua rau nws zoo tagnrho rau kev siv qhov kub thiab txias tsis tu ncua xws li cov cuab yeej ua haujlwm kub thiab siab -kub li qub.
Superior Corrosion Resistance
Nrog kwv yees li 30% chromium cov ntsiab lus, Stellite 6 qhia tau zoo corrosion kuj nyob rau hauv oxidizing acids (piv txwv li, nitric acid), nruab nrab concentrated tsis yog - oxidizing acids (xws li, tsawg dua los yog sib npaug rau 50% sulfuric acid), thiab alkaline daws. Nyob rau hauv dej hiav txwv thiab chloride ib puag ncig, nws feem ntau nthuav tawm pitting corrosion es tsis zoo corrosion. Nws cov corrosion kuj nyob rau hauv siab -kub cua kub uas muaj sulfur thiab chlorine yog tshwj xeeb tshaj yog tsim nyog, ua rau nws yog ib tug zoo xaiv rau cov kev siv uas corrosion thiab hnav coexist, xws li tshuaj ua, petrochemicals, thiab flue gas desulfurization.
Zoo heev Machinability thiab Weldability
Stellite 6 yog ib qho ntawm cov qib machinable thiab weldable tshaj plaws ntawm cobalt-raws li alloys. Nws tuaj yeem ua tau nyuaj siv ntau yam txheej txheem sib tshooj xws li PTA (Plasma Transferred Arc), TIG, MIG, thiab oxy-acetylene vuam. Nws qhov cuam tshuam rau kub tawg yog qhov qis dua qib siab - carbon qib. Preheating rau 300-500℃thiab qeeb txias tom qab vuam yog feem ntau txaus. Kev txwv tsis pub siv yog ua tau nyob rau hauv qhov mob annealed, nrog rau qhov kawg tiav pom zoo los ntawm kev sib tsoo lossis Hluav Taws Xob Hluav Taws Xob (EDM).
