904L (1.4539) Stainless Steel

904L (1.4539) is one of the best stainless steel grade for corrosion resistance. This grade contains very high level of nickel, molibdenium, chromium and combinations of all these elements makes this stainless steel grade very resistant to corrosion resistance. 904L is the strongest material to corrosion at Bircelik and if this grade is not enough, then nickel alloys or titanium has to be choosen, because rest of the stainless steel grades will not survive if 904L is not enough. 904L has also a very good anti-magnetic property and for alot of applicatipons, this is another reason to use 904L stainless steel grade. 904L has a very low content of carbon and this is also improving this grades corrosion resistance level.
