FAQ
2304 (1.4062) piv rau 304L (1.4307) thiab 316L (1.4404) li cas?
2304 muaj kwv yees li ob npaug ntawm cov khoom muaj zog ntawm ob qho tib si 304L thiab 316L (400 MPa vs . 200 MPa), ua kom muaj kev txuag hnyav hauv cov qauv tsim thiab tso cai rau cov khoom siv thinner. Nws cov corrosion kuj nyob ntawm 304L thiab 316L, nrog PREN 24-26 muab cov pitting zoo dua li 304L (PREN 18-20) tab sis tsawg dua 316L (PREN 24-26 nyob ntawm seb muaj pes tsawg leeg). Nws muab kev tiv thaiv zoo tshaj plaws rau chloride kev nyuaj siab corrosion cracking piv rau ob qib austenitic . 2304 feem ntau yog tus nqi zoo dua li 316L thiab tus nqi ruaj khov vim qis nickel cov ntsiab lus. Txawm li cas los xij, 304L thiab 316L muab cov qauv zoo dua rau cov duab nyuaj thiab muaj zog dua ntawm qhov kub thiab txias heev . 2304 feem ntau yog xaiv los ua ib qho kev siv zog ntau dua rau 304L, lossis ua lwm txoj hauv kev lag luam rau 316L qhov twg nws cov corrosion kuj txaus.
Dab tsi yog qhov kev txiav txim siab vuam rau 2304 (1.4062) duplex stainless hlau?
Vuam 2304 yuav tsum tswj xyuas qhov sib npaug ferrite-austenite microstructure rau cov khoom zoo. Cov kev coj ua uas pom zoo suav nrog kev siv qhov sib txuam lossis me ntsis dhau ntawm- cov hlau nplaum uas muaj hlau (feem ntau yog 2209 hom), tswj cov khoom siv hluav taws xob (0.5-2.5 kJ/mm), thiab tswj qhov kub ntawm qhov sib txawv hauv qab 150℃. Tiv thaiv roj nrog nitrogen ntxiv (feem ntau Ar + 2-3% N2) pab tswj cov ntsiab lus nitrogen thiab txhawb kev tsim cov austenite hauv cov hlau vuam. Preheating feem ntau tsis tas yuav tsum tau ua, thiab tom qab-weld kev kho cua sov tsis tsim nyog. Cov ntsiab lus qis qis ua rau 2304 zam ntau dua rau vuam ntau dua - qib alloyed duplex, nrog lub qhov rai ua haujlwm dav dua thiab txo qhov kev pheej hmoo ntawm kev tsim cov theem tsis zoo. Rau qhov zoo tshaj plaws corrosion kuj nyob rau hauv ib puag ncig hnyav, over-alloyed muab tub lim hlau yuav raug txiav txim siab los them rau ib qho kev poob nitrogen thaum lub sij hawm vuam.
