ASTM A213, A269 904L tuubooyinka isku duuban ee aan birta lahayn ee Shiinaha
Alloy 904L waa bir aan xasiloonayn, austenitic austenitic ahama oo sarreeya oo leh kaarboon yar.Waxaa si weyn loogu isticmaalaa codsiyada halka sifooyinka daxalka ee TP316/L iyo TP317/L aysan ku filneyn.Alloy sidoo kale waxay bixisaa qaabayn heer sare ah, weldability, iyo adkaanta.Ku darida naxaasta waxay siinaysaa daawaha 904L guryaha u adkaysta daxalka kuwaas oo ka sarreeya birta caadiga ah ee nikkel chrome.Tusaalooyinka waxaa ka mid ah caabbinta sulfuric, phosphoric, iyo acetic acids.

Farsamaynta
Alloy 904L waa non-magnetic in xaaladaha oo dhan oo uu leeyahay qaabayn heer sare ah iyo weldability.Qaab dhismeedka austenitic sidoo kale wuxuu siinayaa fasalkan adkeysi aad u wanaagsan, xitaa ilaa heerkulku hooseeyo.
Codsiyada Warshadaha
Habka Kiimikada
Waxyaabaha ay ka kooban tahay chromium iyo nikkel sare, oo ay weheliso ku darida molybdenum iyo naxaas, waxay caawisaa daawaynta 904L inay u istaagto sulfuric, phosphoric iyo acetic acids.Tani waxay si gaar ah faa'iido u leedahay soo saarista asiidhka iyo bacriminta.
