ASTM A249 TPTA21 Stainless Hlau Welded Yeeb Rau Boiler Daim Ntawv Thov
ASTM A249 TP249 Tp321 Stainless hlau welded yeeb nkab yog tsim rau boilers vim nws siab {2} mus rau intergranular lub zog (ib qho txiaj ntsig ntawm titanium alloy stabilization). Cov ntaub ntawv yuav tsum tau raws li cov tshuaj, kev kuaj tshuab, yuav tsum muaj cov kev tshuaj ntsuam xyuas thiab kev kuaj mob kub, thiab kev sim hydrostatic / tsis muaj kev kuaj mob. Tsim mus rau welded Austenitic cov qauv yeeb nkab steel, cov yeeb nkab muaj nyob rau hauv ntau yam ntawm cov duab thiab ua tiav rau cov ntawv thov xws li cov roj av, thiab cov hloov pauv kub.
Dab tsi yog ATM code rau 304 stainless hlau yeeb nkab?
ASTM A312 TP 304
ASTM A312 TP 304/304 / 304L Cov yeeb nkab steel hlau yog qhov feem ntau siv thiab siv tau siv stainless hlau ntawm kev ua lag luam. Cov qib no ntawm stainless hlau yog Austenitic chromium alloys, tseem hu ua "18/8" Chromium li qub thiab 8% npib tsib xee.
Tp321 yog cov khoom siv tshwj xeeb stainless hlau nrog cov tshuaj lom neeg hauv qab no thiab cov khoom:
TP321 is a type 321 stainless steel material containing 17-19% chromium, 9-12% nickel, 2-3% silicon, a minimum of 0.04% phosphorus, 0.30% manganese, and 0.075% niobium.
ASTM A249 TP249 TPTAX Cov Hlau Hluav Taws Xob Cov Hluav Taws Xob Ua Phem Kub Muaj cov khoom siv hluav taws xob ua kom zoo, kub thiab txias thiab muaj txiaj ntsig zoo. Lawv kuj nthuav qhia kev tiv thaiv colosion zoo tshaj plaws hauv chav tsev ceev thiab muaj zog corrosion tsis kam nyob rau hauv vaporized tshaj tawm.
ASTM A249 TPUPE Cov hlau cua sov sov cov hlau hluav taws kub muaj cov txheej txheem zoo thiab tuaj yeem ua haujlwm txias, nrog rau kev nyab xeeb txias. Vim yog lawv cov ntsiab lus chromium cov ntsiab lus, Tp321 Cov cua sov ua kom muaj siab thiab tswj hwm kev ua kom haum heev. Kev Ua Haujlwm Hauv Tapp3 kuj muaj cov tshuaj tiv thaiv cua sov kuj tseem muaj zog oxidation tsis kam, thiab cov dej vapor corrosion, thiab ua kom pom cov kev ua kom ntub dej kub.
Tsis tas li ntawd, Tp321 Cov Khoom Siv Hluav Taws Xob Tshav Kub Kub nthuav qhia cov khoom siv hluav taws xob, xws li cov khoom siv hluav taws xob, cov kev tswj hwm, thiab magnitoelectric txuas coupling li.
TPP31 cov hlau stainless kub cov leeg uas tau ntsib Astm A249 cov qauv tshuaj, thiab siv cov ntawv thov ua lag luam xws li xws li cov ntaub ntawv hauv tsheb, cov khoom siv, thiab kev hloov pauv hluav taws xob.
