| In-line Solution Annealing ntawm Stainless Hlau Welded Yeeb Nkab |
In-line tov annealing ntawm stainless hlau yeeb nkab yog ib tug tas mus li kev kho cua sov txheej txheem siv thaum lub sij hawm ntau lawm kom ua tau ib tug uniform austenitic microstructure thiab txhim khu corrosion kuj. Cov yeeb nkab yog rhuab mus rau qhov kev daws teeb meem annealing kub, feem ntau ntawm 1000 ° C thiab 1150 ° C, thiab tom qab ntawd txias txias, feem ntau siv dej quenching lossis yuam cua txias. Cov txheej txheem no dissolves carbide precipitates thiab tiv thaiv intergranular corrosion, xyuas kom meej cov khoom thiab nto zoo raws li thoob ntiaj teb cov qauv. In-line tov annealing txhim kho kev tsim khoom zoo thaum tswj xyuas cov khoom lag luam zoo ib yam.
