Inconel® 625 is an austenitic nickel-base superalloy with excellent resistance to oxidation and corrosion over a broad range of conditions, including jet engine and chemical process applications. This alloy has greater corrosion resistance when compared to 718 at high temperatures. Also known as alloy 625, it has outstanding strength and toughness at temperatures ranging from cryogenic to 2000°F (1093°C), which is derived primarily from the solid solution strengthening of columbium and molybdenum in a nickel-chromium matrix.Common trade names include Nickel 625, Alloy 625, and Inconel® 625.
625 round bar inventory - AMS 5666
We supply round bar stock in .250" - 7.000" diameters. Its superior corrosion and oxidation resistance at high temperatures make it ideal for the aerospace industry, naval applications, chemical processing, and the oil and gas industries. Alloy 625 is virtually immune to corrosion in marine environments and is used extensively in the hot section of jet engines and in high temperature corrosive environments found in the chemical processing industry. Our bar stock comes in standard inventory lengths of 10-12 feet rl's. It requires a minimum yield strength of 60,000 psi at room temperature for bars under 4 inches in diameter. Mechanical properties for bars 4 inches in diameter and larger are to be agreed upon by purchaser and vendor. Exact specification is AMS 5666.

Properties of 625 Inconel®
|Nickel||Chromium||Molybdenum||Columbium plus Tantalum|
Non-magnetic. 625 alloys can be used for parts requiring both corrosion and oxidation resistance up to 2000ºF (1093°C). This grade has outstanding resistance to creep and stress rupture up to 1200ºF (649°C), and oxidation and scaling resistance up to 2000ºF (1093°C).
Hardness of Aerodyne stock is typically 185 BHN and never higher than 287 BHN by specification. The microstructure remains austenitic at both elevated and low temperatures. 625 cannot be hardened by heat treatment but can be hardened by cold working. During cold working, this grade work hardens more rapidly than austenitic stainless steels.
Rating: 16% of B-1112
Typical stock removal rate: 25 surface feet/minute with high speed tools. 100 surface feet/minute with carbide.
625 plate can be welded by most customary techniques, such as inert gas tungsten arc (TIG), gas metal arc welding (GMAW), plasma, electron beam, submerged arc and resistance welding. If excessive heat input and oxidation are avoided during welding, This alloy can be put into service without any subsequent postweld thermal treatments.
Use relatively heavy cuts and low speeds to minimize surface work hardening
Density: 0.305 lbs/in3, 8.44 g/cm3
