ASTM A213, A269 904L simbi isina tsvina yakamonerwa tubing muChina
Alloy 904L isimbi isina kugadzikana, yakakwira alloy austenitic Stainless simbi ine yakaderera kabhoni.Inoshandiswa zvakanyanya mumashandisirwo apo iyo corrosion properties yeTP316/L uye TP317/L haina kukwana.Iyo alloy inopawo yakanakisa kuumbwa, weldability, uye kuoma.Kuwedzerwa kwemhangura kunopa alloy 904L corrosion resistant properties iyo yakakwirira kune yakajairwa chrome nickel simbi isina tsvina.Mienzaniso inosanganisira kuramba sulfuric, phosphoric, uye acetic acids.

Fabrication
Alloy 904L isiri-magnetic mumamiriro ese uye ine yakanakisa formability uye weldability.Iyo austenitic chimiro chinopawo iyi giredhi kusimba kwakanyanya, kunyangwe pasi kusvika kune cryogenic tembiricha.
Indasitiri Applications
Chemical Process
Yayo yakakwira chromium uye nickel yemukati, pamwe nekuwedzera kwe molybdenum nemhangura, inobatsira alloy 904L kumira kune sulfuric, phosphoric uye acetic acid.Izvi zvinonyanya kukosha mukugadzirwa kweasidhi nefetereza.
