Monel K500 cov khoom siv lub cev thiab cov khoom siv kho tshuab
Alloy K-500 yog npib tsib xee-tooj liab alloy uas sib txuas cov kev tiv thaiv zoo heev ntawm Alloy 400 nrog ntau zog thiab hardness. Alloy K-500 muab 3 lub sij hawm ntau zog tawm los ntawm Alloy 400. Cov khoom no txhim kho tau ua tiav feem ntau los ntawm kev sib ntxiv ntawm txhuas thiab titanium cov ntsiab lus thiab lub hnub nyoog hardening rau npib tsib xee ua lub ntsiab. Thaum lub sij hawm lub hnub nyoog hardening txheej txheem, cov kab ntawm Ni3 (titanium, txhuas) hais precipitated thiab nkag mus rau hauv matrix.
Tuav ntawm 982 degree rau 30 feeb thiab tom qab ntawd dej quench thiab anneal. Tuav ntawm 593 degree -607 degree rau 16 teev thiab tom qab ntawd maj mam txias hauv qhov cub ntawm 9.4 degree - 3.8 degree txhua teev txog 482 degree . Tom qab ntawd nws yog txias los ntawm 482 degree mus rau chav tsev kub, uas tej zaum yuav xav tau ib co boiler txias, cua txias los yog quenching, tsis hais tus nqi cua txias.
K-500's tsis tshua muaj hlau nplaum permeability, siab zog thiab zoo corrosion kuj tau dav siv, feem ntau nyob rau hauv cov roj zoo nrhiav cov cuab yeej thiab cov khoom siv hluav taws xob.
