Nws kuj tseem muaj zog dua cov neeg kho tshuab me ntsis.1.4563 feem ntau yog xaiv rau cov ntawv thov corrosive hnyav dua qhov twg ob qho tib si pitting tsis kam thiab kev tiv thaiv corrosion kuj tseem ceeb heev.
Dab tsi yog qhov kev txiav txim siab vuam rau 1.4563 stainless hlau?
Vuam 1.4563 yuav tsum tau ceev faj tswj kom muaj kev tiv thaiv corrosion. Cov kev coj ua uas pom zoo suav nrog kev siv sib txuam lossis ntau dua - alloyed muab tub lim hlau (xws li Alloy 625 lossis siab dua-qib austenitic fillers), tswj cov cua sov kom tsis txhob muaj kev sib txuam ntau dhau, thiab ua kom muaj kev tiv thaiv kom tsis txhob muaj nitrogen. Tom qab-welding tu yog qhov tseem ceeb los tiv thaiv corrosion hauv thaj tsam weld.
