Zoo heev Hardness thiab hnav tsis kam
Stellite 19 imparts zoo tiv thaiv abrasive thiab adhesive coj mus rau lub alloy los ntawm kev tsim ntawm uniformly faib M₇C₃- hom carbides. Cov hardness ib txwm nyob rau hauv raws li - nrum los yog weld- tej yam kev mob tso nyiaj yog HRC 38-46 (kwv yees HV 350-450). Nws hnav tsis kam tshaj li ntawm Stellite 6, thiab nws cov tawv tawv yog siab dua li cov qib siab carbon, ua rau nws tsim nyog rau cov ntawv thov uas hnav nruab nrab thiab muaj kev cuam tshuam me ntsis coexist.
Zoo Siab -Tub kub Hardness thiab Oxidation Resistance
Stellite 19 khaws cia li 30 HRC hardness ntawm 600 degree, txog 23 HRC ntawm 760℃(1400℃F), thiab txog 18 HRC ntawm 870℃(1600℃F). Cov ntsiab lus siab chromium txhawb kev tsim cov Cr₂O₃ oxide zaj duab xis rau saum npoo. Tom qab raug cua ntawm 800℃rau 1000 teev, oxidation hnyav nce yog tsawg dua 1 mg / cm². Nws cov oxidation kuj zoo dua rau cov hlau feem ntau -raws li hnav- cov ntaub ntawv resistant, ua rau nws haum rau siab - kub cyclic daim ntaub ntawv xws li kub shearing thiab kub extrusion.
Zoo Corrosion Resistance
Nrog kwv yees li ntawm 30% chromium cov ntsiab lus, Stellite 19 nthuav tawm qhov zoo corrosion kuj nyob rau hauv oxidizing acids (xws 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 qhia pitting corrosion es tsis zoo corrosion, thiab tuav ruaj khov corrosion kuj nyob rau hauv siab -kub cua uas muaj sulfur thiab chlorine.
Zoo Machinability thiab Weldability
Stellite 19 muaj kev sib txuas zoo dua thiab ua haujlwm tau zoo dua li nruab nrab - mus rau - qib siab carbon. Nws tuaj yeem tso tau siv PTA, TIG, thiab oxy-acetylene vuam txoj kev. Preheating rau 300-450℃thiab qeeb txias tom qab vuam tau pom zoo kom txo qis kev pheej hmoo ntawm kub tawg. Kev siv lub tshuab tsis muaj peev xwm tuaj yeem ua tau nyob rau hauv cov xwm txheej annealed, nrog kev ua tiav kawg pom zoo siv kev sib tsoo lossis hluav taws xob tawm machining (EDM).
