An Inconel 625 superalloy, or high-performance alloy, bar is an amalgam that shows a couple of key characteristics: brilliant mechanical strength, assurance from thermal creep deformation, incredible surface solidness, and insurance from corrosion or oxidation.
Properties
Inconel 625 bar are responsible for its outstanding corrosion resistance in a variety of severe operating environments along with resistance to oxidation and carburization in high temperature service. The alloy is resistant to pitting, crevice corrosion, impingement corrosion, intergranular attack and is almost immune to chloride stress corrosion cracking.

The alloy is resistant to a variety of corrosive media from highly oxidizing to moderately reducing. Alloy 625 is highly resistant to hot geothermal fluids comparable to titanium grade 2. The high alloy content of Inconel 625 round bar enables it to withstand a wide variety of severe corrosive environments.
