Iska caabista xasaasiyadda

Alloy 17-4 ph ayaa ka hor istaagaya weerarada wasakhaysan ee ka fiican mid kasta oo ka mid ah heerka caadiga ah ee aan la cuni karin oo la barbar dhigo Aly 304 ee warbaahinta badankood.

Haddii ay jiraan khataro suurogal ah oo ku saabsan dildilaaca walaaca fekerka, heerkulka da 'weyn leh markaa waa in laga xushaa 1022 ° F (550 ° C), gaar ahaan 1094 ° F (590 ° C). 1022 ° F (550 ° C) waa heerkulka ugufiican ee kuleylka ee warbaahinta khloride-ka.

1094 ° F (590 ° C) waa heerkulka ugufiican ee ku jira warbaahinta H2S ee warbaahinta H2S.

Alloy-ka waxaa lagu xiraa qalooc ama weel galka ah haddii ay ku dhacdo biyaha badda oo fadhiya muddo dheer.

Waa isku adkeysi u adkaysata kiimikada qaarkood, batroolka, warqad, caano iyo warshado ka baaraandeg cunno (oo u dhiganta fasalka 304L.
