UNS C44300 Admiralty Brass Tube PDF
C44300 Brass vs. C46400 Brass
C44300 (Admiralty Brass): Cu-Zn-Sn alloy. Nws yog qhov tseem ceeb ntawm 70/30 tooj dag (70% Cu, 29% Zn, 1% Sn) nrog me me ntxiv ntawm Arsenic (As) lossis qee zaum Antimony / Sb lossis Phosphorus / P.
C46400 (Naval Brass): Cu-Zn-Sn alloy. Nws yog feem ntau hu ua 60/40 tooj dag (60% Cu, 39.2% Zn, 0.8% Sn).
Txhais cov yam ntxwv & Lub hom phiaj ntawm Tin (Sn)
C44300: Lub 1% Tin yog ntxiv feem ntau los txhim kho corrosion kuj, tshwj xeeb tshaj yog tiv thaiv dezincification thiab impingement nres nyob rau hauv dej ntsev thiab chav condensate.
C46400: Lub ~ 1% Tin yog ntxiv feem ntau los ua kom muaj zog thiab hardness piv rau cov tooj dag zoo tib yam, thaum tseem muab kev tiv thaiv corrosion zoo.
C44300 vs C46400
C44300: Cov Arsenic (As) ntxiv (~ 0.02-0.10%) yog qhov tseem ceeb. Nws ua raws li tus inhibitor los tiv thaiv dezincification, ib daim ntawv ntawm kev xaiv leaching qhov twg zinc corrodes tam sim ntawd, tawm hauv ib tug ntxeem tau tooj liab qauv.
C46400: Nws tsis muaj arsenic. Nws tsis kam mus rau dezincification hauv dej hiav txwv yog qhov zoo tab sis feem ntau tsis zoo rau inhibited brasses zoo li C44300.
Mechanical Properties
C44300: Lub zog zoo thiab ductility, tab sis nws cov khoom siv kho tshuab yog qhov thib ob rau nws qhov kev tiv thaiv corrosion / yaig.
C46400: Muaj zog tensile ntau dua, tawm lub zog, thiab hardness dua C44300. Nws yog cov khoom siv muaj zog, muaj zog dua.
Corrosion Resistance
C44300: Zoo heev thiab tshwj xeeb. Superior tiv thaiv dezincification, yaig-corrosion, thiab biofouling hauv cov dej hiav txwv ntws, dej brackish, thiab chav condensate. Cov arsenic inhibits cov txheej txheem corrosion.
C46400: zoo heev corrosion kuj nyob rau hauv marine ib puag ncig. Muaj zog tiv thaiv corrosion dej ntsev, tab sis muaj kev cuam tshuam rau dezincification dua li inhibited admiralty tooj dag nyob rau hauv stagnation los yog qeeb - txav dej.
Cov ntawv thov tseem ceeb
C44300: Yuav luag tsuas yog siv rau cov cua kub exchanger thiab condenser raj, raj ntawv, thiab lwm yam khoom nyob rau hauv marine, fais fab nroj tsuag, thiab desalination cog systems qhov twg tshav kub hloov thiab ntev -lub sij hawm corrosion kuj yog qhov tseem ceeb.
C46400: Siv rau ntau yam ntawm marine hardware thiab cov khoom siv. Cov ntawv thov feem ntau suav nrog cov kiv cua shafts, twj tso kua mis shafts, valve stems, fasteners, bolts, txiv ntseej, marine fittings, thiab lwm yam siab -lub zog qhov chaw nyob rau hauv kev sib cuag nrog seawater.
