Piv nrog rau austenitic stainless hlau yeeb nkab, duplex stainless hlau yeeb nkab lub shortcomings yog raws li nram no:
1) universality ntawm daim ntawv thov thiab multi-faceted li austenitic stainless hlau, piv txwv li, nws siv kub yuav tsum tau tswj ntawm 250 degrees Celsius.
2) nws cov yas toughness dua austenitic stainless hlau qis, txias, kub ua tshuab thiab tsim kev ua tau zoo li austenitic stainless hlau.
3) lub hav zoov ntawm qhov nruab nrab qhov kub thiab txias, qhov xav tau kev tswj xyuas nruj ntawm kev kho cua sov thiab cov txheej txheem vuam txheej txheem kom tsis txhob muaj qhov tshwm sim ntawm qhov teeb meem, kev ua haujlwm puas tsuaj.
