Inconel 625 Bar
Inconel 625 (UNS N06625) is a nickel-based superalloy with excellent resistance to oxidation and corrosion. The nickel-chromium matrix of this material is reinforced by the addition of molybdenum and niobium, which is alloyed through solid solution strengthening. This process allows alloy Inconel 625 to maintain high strength and toughness at temperatures ranging from cryogenic up to 1800°F (982°C). It is non-magnetic, austenitic, and displays high tensile strength, fabricability, and brazeability. Due to its high nickel content, this alloy is nearly immune to chloride ion stress-corrosion cracking and pitting, which is commonly found in thin-walled seawater applications like heat exchangers, fasteners, and cable sheathing.

Dimensions and Tolerance

Working with this product

Alloy 625 can be cold formed, hot worked, and machined through most standard methods. Hot forming should be done at temperature ranges of 1700 – 2150°F (927-1177°C), and care should be taken when cold working and machining, as it work hardens more quickly than more traditional austenitic stainless steels. Recommend using rigid, powerful machines with sharp tooling at positive rake angles, with tools changed frequently to maintain sharpness. Heavy constant feeds are advised to maintain a positive cutting action with proper lubrication. All 625 may be welded through typical gas shielded processes.


Heat treatment

This alloy has three primary heat treatments – solution annealing at 2000-2200°F (1093 – 1204°C) with air or rapid quenching, annealing at 1600-1900°F (927-1038°C) with air or rapid quenching, and stress relieving at 1100-1600°F(593 – 900°C) with air quenching. Each process results in different characteristics, with the high temperature annealing used for applications above 1500°F where creep resistance is important. The medium temperature annealing provides optimal tensile and rupture properties up to 1900°F (1038°C), while the stress relieved state is recommended for applications under 1200°F (649°C), where maximum fatigue, hardness and yield strength are required.
