Cov ntsiab lus tseem ceeb muaj nyob hauvUNS C22000yog tooj liab (Cu), lead (Pb), zinc (Zn), thiab tin (Sn). Cov tshuaj muaj pes tsawg leeg ntawm cov hlau no suav nrog 67% tooj liab, 28% zinc, 5% txhuas, 0.25% tin, thiab lwm yam khoom xws li hlau (Fe), manganese (Mn), nickel (Ni), sulfur (S) thiab phosphorus (P). Cov ntsiab lus no ua ke los tsim cov hlau nplaum uas tiv taus corrosion los ntawm feem ntau cov kua qaub thiab alkalis ntawm chav tsev kub.
Bronze 220Nws muaj qhov kub thiab txias ntawm 930 degree (1706 degree F) thiab qhov ceev ntawm 8.8 g / cm3. Nws raug cais raws li alpha-beta tooj dag vim nws muaj ob qho tib si alpha ( ) thiab beta ( ) theem hauv nws cov microstructure. Lub hardness ntau ntawm 70 txog 95 Brinell (HBW), nrog lub zog tensile ntawm 600 MPa (87 ksi). Nws pom zoo hnav tsis kam ua tsaug rau nws cov ntsiab lus txhuas siab, ua rau nws zoo tagnrho cov khoom siv rau bearings thiab bushings.
Mechanical Properties ntawm220 Nyiajsuav nrog qib siab ntawm lub zog vim nws cov hlau sib xyaw ua ke, uas pab ua kom cov khoom siv ductility. Nws kuj muaj cov thermal stability zoo heev, ua rau nws tsim nyog rau kev siv kub xws li roj turbines lossis boilers qhov kub tuaj yeem ncav cuag 450 degree (842 degree F). Tsis tas li ntawd, cov khoom no muaj kev ua haujlwm zoo, ua kom yooj yim shaping thaum lub sij hawm tsim khoom xws li forging lossis casting.
Bronze C220muaj ntau daim ntawv thov vim nws lub cev muaj zog, xws li tiv thaiv corrosion los ntawm feem ntau cov kua qaub thiab alkalis thiab zoo thermal stability, tso cai rau nws siv nyob rau hauv high-temperature daim ntaub ntawv xws li roj turbines los yog boilers yam tsis muaj kev cuam tshuam nws zoo los yog kev ncaj ncees lub sij hawm. Feem ntau siv muaj xws li valve stems, xauv lub cev, piston rings, bearings, bushings, thiab hluav taws xob fittings. Txhawm rau kom muaj kev tiv thaiv corrosion siab tshaj plaws thaum siv Bronze 220, nws yuav tsum tau kho cua sov ua ntej daim ntawv thov kom ua kom muaj txiaj ntsig zoo ntawm cov hlau alloy cov tshuaj muaj pes tsawg leeg, suav nrog nce hardness thiab txhim kho tensile zog.
C22000xav tau kev npaj kom meej, qhov tseeb hauv kev ntsuas, thiab kev txawj ntse uas pab tsim cov khoom zoo nkauj nrog lub zog zoo. Nrog rau qhov kev paub no, machinists tuaj yeem tsim cov khoom zoo yam tsis muaj kev txiav txim siab los yog ceev thaum khaws cov nqi tsim khoom qis.
