Irin Alagbara 904/904L
Awọn orukọ Iṣowo ti o wọpọ: Alloy 904L ,N08904, W.Nr1.4539,N08904 ,Cr20Ni25Mo4.5Cu
904L jẹ Super Austenstic Alagbara Irin pẹlu kekere erogba akoonu.Ipele naa jẹ ipinnu fun lilo labẹ awọn ipo ibajẹ nla.O ti jẹ afihan ohun elo fun ọpọlọpọ ọdun ati pe o ti ni idagbasoke ni akọkọ lati koju ipata ni sulfuric acid dilute.O jẹ idiwọn ati fọwọsi fun lilo ọkọ oju-omi titẹ ni awọn orilẹ-ede pupọ.Ni igbekalẹ, 904L jẹ austenitic ni kikun ati pe ko ni itara si ferrite ojoriro ati awọn ipele sigma ju awọn iwọn austenitic ti aṣa pẹlu akoonu molybdenum giga.Ni ihuwasi, nitori apapọ awọn akoonu giga ti chromium, nickel, molybdenum ati bàbà 904L ni resistance to dara si ipata gbogbogbo, pataki ni awọn ipo imi-ọjọ ati phosphoric.

Kini idi ti Alloy 904L?
•Rere resistance to pitting ipata ati crevice ipata
•Giga resistance si wahala ipata wo inu, intergranular, ti o dara machinability ati weldability
•Ninu gbogbo awọn oriṣi ti phosphates904L alloy resistance resistance jẹ superior si irin alagbara irin lasan.
•Ni acid acid acid oxidizing ti o lagbara, ni akawe si alloy giga laisi iwọn irin molybdenum, 904L ṣe afihan idena ipata kekere.
•Alloy yii ni aabo ipata to dara julọ ju irin alagbara irin ti aṣa lọ.
•Din oṣuwọn ipata ti ọfin ati awọn ela fun akoonu giga ti nickel, ki o ni resistance to dara si ipata wahala.fifọ, ni agbegbe ti ojutu kiloraidi, ifọkansi ti ojutu hydroxide ati hydrogen sulphide ọlọrọ.
