ASTM A269 khoom yog dab tsi?
ASTM A269 npog stainless hlau tubing nrog ib tug tshwj xeeb nominal phab ntsa thickness npaj los tiv thaiv corrosion thiab ua hauj lwm nyob rau hauv qis-los yog high-temperature ib puag ncig. Xws li cov khoom siv kho tshuab thiab cov kev xav tau kuaj. Cov kav dej uas ua raws li tus qauv no feem ntau muaj qhov ntev thiab phab ntsa thicknesses: puab txoj kab uas hla ntawm 6.4 hli los yog ntau dua thiab nominal phab ntsa thickness ntawm 0.51 hli los yog ntau dua, xyuas kom meej lawv tsim nyog los tiv thaiv corrosion thiab ua hauj lwm nyob rau hauv qis thiab kub ib puag ncig.
ASTM A269 TP304 Stainless Hlau Round Tube yog dab tsi?
ASTM A269 TP304 Stainless Hlau Round Tube yog austenitic stainless hlau round raj, seamless los yog welded, dav siv nyob rau hauv qis thiab nruab nrab siab siab cov ntaub ntawv thauj mus los, resistant rau corrosion thiab kub kub.
TP304 (UNS S30400) yog lub hom phiaj dav dav 18-8 stainless hlau nrog zoo corrosion kuj thiab machinability. Nws tuaj yeem ua seamless (txias kos / kub dov) los yog welded (xws li ERW) thiab tau txais kev kho cua sov (dej quenching mus txog 1040 degree) kom ntseeg tau tias muaj kev tiv thaiv intergranular corrosion. Cov txheej txheem saum npoo muaj xws li pickling, ci ntsa iab annealing (BA), mechanical polishing (MP) thiab electropolishing (EP) kom ua tau raws li cov kev cai huv huv ntawm cov zaub mov, tshuaj thiab lwm yam lag luam.
Kev sib xyaw ntawm ASTM A269 TP304
ASTM A269 TP304 yog tus qauv qib ntawm austenitic stainless hlau npaj rau kev tsim cov kav dej nrog kev tiv thaiv corrosion, qis thiab kub. Nws yog tsim los ntawm 18% chromium thiab 8% npib tsib xee, uas yog vim li cas nws tseem hu ua classic stainless hlau.8/18.
