ASTM A928 QIB 1 S32750 SUPER DUPLEX Welded Yeeb Nkab Pom Cov nruj thiab cov kev tsim ua kom nruj thiab ua tau zoo ntawm ASTM A928.
Cov khoom siv gnee undless stainless efw (hluav taws xob fusion welded) pipes tsim los ntawm s32750 steel (tseem hu ua 2507 suplex). Lub chav dej super duplex no tau txhawb nrog qib siab ntawm chromium, molybdenum thiab nitrogen, uas txhim kho nws cov neeg kho tshuab thiab corrosion tsis kam.
Cov "qib 1" qhia tau tias cov yeeb nkab yog tsim siv hlau rau ob lub vuam, ua raws li kev siv vuam, raws li ultrasonicound / UT) los xyuas kom meej cov khoom siv dawb. Tom qab, cov kav dej tau raug kom daws cov anchouring ntawm 1050-1150 degrees, ua raws li los ntawm dej quenching, tshem tawm cov kev ntxhov siab thiab sib npaug + Austenite).
Cov kav dej no muab cov khoom siv tshwj xeeb rau kev pitting, kev nyuaj siab corrosion thiab ntug dej kom zoo li cov roj av thiab cov dej ntws tawm ntawm cov roj thiab cov dej hiav txwv muaj zog thiab corrosion durability yog qhov tseem ceeb.
