Inconel® 625 bars are used in industries requiring super alloys that don’t oxidize or corrode and maintain their integrity across a full range of extreme temperatures. Thanks to its nickel base, reinforced with a columbium-tantalum alloy, molybdenum, niobium and chromium, Inconel 625 bars are available from Altemp Alloys in the following specifications:
ASME SB-446 Gr. 1
ASTM B-446 Gr. 1

Key Features & Properties
Inconel 625’s combination of refractory metals and alloys exhibit uniform performance at temperatures ranging from cryogenic to over 1000 degrees Celsius/2000 degrees Fahrenheit. Additional performance characteristics include scaling and oxidation resistance, stabilization during welding, resistance to chloride stress and corrosion cracking, and outstanding fatigue strength. Inconel 625 bars, sheets, plates and forgings are non-magnetic. This makes Inconel 625 a mainstay of the aerospace, hardware manufacturing, marine engineering, chemical processing and power generation industries.
Inconel 625 (UNS N06625) corrosion resistance includes harsh and hostile environments, such as:
- Salt water
- Fresh water
- Neutral salts
Some applications require Inconel 625 to be pickled before use. To do this, Inconel 625 bars must be bathed in sodium hydride, then submerged in sulfuric acid, precision heated to a temperature of 74 degrees Celsius/165 degrees Fahrenheit for three minutes, then given a 25-minute bath in a nitric hydrofluoric compound heated to 63 degrees Celsius/145 degrees Fahrenheit before rinsing.
Altemp Alloys offers Inconel 625 bar as well as sheet, plate, forgings and tubing.
