C-276 alloy muaj ntau yam tshuaj sib raug zoo thiab tuaj yeem ua tau zoo nyob rau hauv ntau qhov chaw corrosive, tshwj xeeb tshaj yog nyob rau hauv muaj cov tshuaj chlorides, sulfuric acid thiab lwm yam tshuaj corrosive heev. cov
Lub ntsiab chemical Cheebtsam ntawm C-276 alloy muaj xws li:
Nickel (Ni): txog 65%
Chromium (Cr): kwv yees li 15%
Molybdenum (Mo): li 4.5%
Hlau (Fe): txog 6%
Tungsten (W): ib qho me me
Lwm cov khoom (xws li cobalt, carbon, thiab lwm yam)
2. Corrosion kuj
Alloy C-276 muaj kev tiv thaiv corrosion zoo heev, uas tau pom tshwj xeeb hauv cov hauv qab no:
Nws muaj zog corrosion kuj nyob rau hauv ntau yam acidic media (xws li sulfuric acid, hydrochloric acid, phosphoric acid thiab nitric acid).
Nws muaj kev tiv thaiv zoo heev rau kev ntxhov siab corrosion tawg hauv qhov chaw uas muaj cov tshuaj chloride, xws li dej hiav txwv lossis sodium hypochlorite, thiab nws qhov tshwm sim ntawm kev ntxhov siab corrosion tawg yog tsawg heev.
Nws kuj nthuav tawm qhov tsis tshua muaj corrosion hauv qhov chaw oxidizing, xws li kub kub concentrated nitric acid.
3. Mechanical zog thiab elongation
Alloy C -276 tsis tsuas yog muaj kev tiv thaiv corrosion zoo heev, tab sis kuj tseem muaj cov khoom siv kho tshuab zoo, tshwj xeeb tshaj yog cov elongation siab. Elongation feem ntau yog siv los ntsuas cov yas deformation muaj peev xwm ntawm cov ntaub ntawv hauv kev sim tensile, uas yog qhov tseem ceeb rau lawv cov kev ua thiab kev siv. Tshwj xeeb:
Nyob rau hauv ib puag ncig kub, qhov elongation ntawm Alloy C -276 yog me ntsis txo, tab sis tseem tuaj yeem khaws cia siab tshaj 30%. Kev sim cov ntaub ntawv qhia tias ntawm 600 degree, nws elongation tseem tuaj yeem ncav cuag 32%.
Lub elongation kev ua tau zoo nyob rau hauv tensile kev nyuaj siab kuj zoo. Nyob rau hauv lub tensile load ntawm 100MPa, lub elongation ntawm cov alloy yog hais txog 45%.
