SB-625 UNS N08904 is a kind of low carbon, high alloy austenitic stainless steel, in dilute sulphuric acid SB-625 UNS N08904 has good corrosion resistance, specially designed for harsh environment corrosion conditions. Has the high chromium content and plenty of nickel content, the addition of copper makes it have strong ability to resist acid, especially for chloride clearance corrosion and stress corrosion cracking are highly resistant, not easy to appear, erosion and fracture pitting resistance slightly better than other steel grade, good machinability and weldability, can be used for pressure vessels.
Key words:SB-625 UNS N08904 alloy steel,SB-625 UNS N08904 stock,SB-625 UNS N08904 competitive price, SB-625 UNS N08904 high quality,SB-625 UNS N08904 supplier, SB-625 UNS N08904 manufacturer.
