Product Description

The picture of Inconel 625 ASME SB-446 round bar

625

Inconel 625 is a nickel-base alloy used both for its high strength and outstanding aqueous corrosion resistance. The strength of alloy 625 is primarily a solid solution effect from molybdenum and columbium. Alloy 625 has excellent weldability and is frequently used to weld AL-6XN alloy. Matching filler metals are also used to join dissimilar metals.
