625       SPEC SHEET

Alloy 625 is 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 weld fillers have excellent weldability and are frequently used to weld AL-6XN® super austenitic stainless steel. Matching filler metals are also used to join dissimilar metals.
