Monel K500 nickel-tooj liab alloy, cov khoom lag luam, cov khoom siv lub cev
Monel K500, zoo tshaj npib tsib xee-tooj hlau alloy paub txog nws lub zog tsis sib xws thiab zoo heev corrosion kuj. Nws qhov tshwj xeeb muaj pes tsawg leeg ntawm kwv yees li 65% npib tsib xee, 33% tooj liab thiab 2% txhuas, ntxiv los ntawm cov khoom siv hlau, manganese, titanium thiab silicon, pab txhawb rau nws qhov kev ua tau zoo tshwj xeeb.
Thaum peb tshawb nrhiav tob tob txog cov tshuaj muaj pes tsawg leeg ntawm Monel K500, nws tsis yog qhov nyuaj los nrhiav nws cov txiaj ntsig zoo: cov ntsiab lus nickel nyob nruab nrab ntawm 63.0-70.0%, tooj liab yog 27.0-33.0%, thiab txhuas yog nyob ntawm 2.30-3.15%. Tsis tas li ntawd, nws tseem nruj me ntsis txwv cov ntsiab lus ntawm lwm cov ntsiab lus, xws li hlau tsis pub tshaj 2.0%, manganese tsis tshaj 1.5%, carbon, silicon, sulfur thiab phosphorus tsis tshaj 0.25% thiab 0.01%.
Nyob rau hauv cov nqe lus ntawm hardness, Monel K500 exhibits zoo heev Rockwell C hardness (HRC) ntawm 28-34, deb tshaj ntau lwm yam high-zog alloys. Nws cov ntsiab lus melting yog siab li kwv yees li 1315 degree (2400℉), kom ntseeg tau tias kev ua haujlwm ruaj khov hauv qhov kub thiab txias. Tsis tas li ntawd xwb, nws qhov siab tshaj plaws ua haujlwm kub tuaj yeem ncav cuag 1100 degree (2000℉), uas qhia tau zoo heev kub tsis kam.
Tsis tas li ntawd, Monel K500 muaj qhov elastic modulus ntawm 180 GPa (26.1 × 106 psi) thiab Poisson tus piv ntawm 0.32, ua kom pom cov khoom zoo heev. Nws qhov ceev yog 8.44 g / cm³ (0.305 lb / in³), ua kom nws muaj txiaj ntsig zoo hauv cov ntawv thov nrog lub zog siab.
Monel K500 kuj ua tau raws li Asmeskas cov qauv ASTM B865, B164, B564, B366, thiab lwm yam, nrog rau cov qauv European EN 10204-3.1, thiab lwm yam, kom ntseeg tau tias nws zoo tshaj plaws thiab kev ntseeg tau. Nws lub zog tawm los mus txog 379 MPa (55 ksi) (tus nqi tsawg kawg), lub zog tensile siab li 965 MPa (140 ksi) (tus nqi qis), thiab elongation kuj nce mus txog 20% (tus nqi tsawg), uas ua pov thawj nws zoo heev. mechanical zog.
Raws li cov ntsiab lus, Monel K500 tau dhau los ua tus thawj coj hauv kev siv zog siab, siab-corrosion-resistant daim ntaub ntawv nrog nws cov cim muaj pes tsawg leeg thiab kev ua tau zoo heev. Txawm hais tias nws yog kev lag luam chemical, marine engineering los yog aerospace thiab lwm yam kev lag luam, nws tau ua kom pom qhov zoo tshaj plaws thiab kev ntseeg tau zoo.
