AISI 904L Stainless simbi (UNS N08904) is high alloy austenitic Stainless simbi. Kana ichienzaniswa ne316L, SS904L ine yakaderera kabhoni (C) zvemukati, yakakwira chromium (Cr) zvirimo, uye zvakapetwa kaviri nickel (Ni) uye molybdenum (Mo) zvirimo.316L, izvo zvinoita kuti ive yakakwira yakanyanya tembiricha oxidation kuramba, pitting kuramba, uye kuramba kuderedza asidi (semuenzaniso, sulfuric acid). Nitrogen (N) inogona kuderedza mwero wekromium carbide kunaya, nekudaro ichidzikisa kunzwisiswa kwekunzwa, uye zvakare inovandudza kuramba kwegomba uye crevice corrosion inokonzerwa nemakloridi. Kunyanya kuwedzera kwayo kwemhangura (Cu) inoita kuti ive yakakosha kune ese maratidziro e sulfuric acid.

Alloy 904L inoita zvirinani kupfuura mamwe austenitic Stainless simbi nekuda kwekukwira kwepamusoro kwe nickel uye molybdenum. Iyo giredhi haina-magnetic mumamiriro ese uye ine yakanakisa formability uye weldability. Iyo austenitic chimiro inopawo iyi giredhi kusimba kwakanyanya, kunyangwe kudzika kusvika kune cryogenic tembiricha Iyo yakakwira chromium yemukati inosimudzira uye inochengetedza passive firimu inochengetedza zvinhu munzvimbo dzakawanda dzinoparadza. Iko hakuna njodzi yeintercrystalline corrosion pakutonhodza kana welding nekuda kweiyo yakaderera kabhoni yemukati. Kupisa kwayo kwakanyanya kwesevhisi kuri pa450°C. Iri giredhi rinonyanya kubatsira mukutonga uye instrumentation tubing application uko 316 uye 317L isina kukodzera.

Alloy 904L yakatanga kugadzirwa kuti imirire nharaunda dzine dilute sulfuric acid. Inopawo kupikisa kwakanaka kune mamwe maasidhi asina kusimba senge inopisa phosphoric acid pamwe neakawanda organic acids.

Alloy 904L inokwenenzverwa zviri nyore uye inogadziriswa neyakajairwa chitoro kugadzira maitiro.

904L Stainless Simbi (SS904L) inoshandiswa mupetroleum, makemikari, fetiraiza, shongwe dzekusimudzira marine, matangi, pombi uye machubhu uye kupisa kunopisa. Rolex nevamwe vanogadzira wachi vanoishandisawo kugadzira wachi
