Product Description


Stainless Steel Pipe Seamless 4 inch 2inch / Seamless Alloy Steel Pipe
Inconel 625 has excellent strength at temperatures up to 816℃. At higher temperatures, its strength is generally lower than that of other solid solution strengthened alloys. Inconel 625 has good oxidation resistance at temperatures up to 980℃ and shows good resistance to aqueous corrosion, but is relatively moderate compared to other more capable corrosion resistant alloys.

Common applications


Even though researchers initially touted its creep strength at high temperatures, it was also shown that alloy 625 could remain nearly corrosion free at ambient to low temperature elevations, like seawater environments or chemical processing of acids and salts. Marine heat exchangers commonly use 625, to isolate corrosive seawater to materials that can endure them, such as 625 based plate and shell and tube heat exchangers.


It is nearly immune to chloride-ion induced stress cracking, by virtue of its high nickel content, and has been used in propellers and propulsion systems as well as wires used in cable sheathing in marine environments. In addition to saltwater corrosion resistance, the high ductility of 625 makes it ideal for fasteners like hex bolts in underwater environments.
