Inconel 625 Round Bar is a nickel-based super alloy that offers a distinctive combination of exceptional qualities. This makes the alloy adaptable and popular across many industrial industries. Across a wide range of high temperature conditions, it has exceptional resistance to oxidation and corrosion.
A combination that exhibits the following important properties is known as an Inconel 625 super alloy, or high-performance alloy: outstanding mechanical strength, protection from thermal creep deformation, fantastic surface solidity, and protection from corrosion or oxidation.
Properties
The outstanding corrosion resistance of Inconel 625 bar in a variety of harsh operating environments, as well as its resistance to oxidation and carburization in high temperature service, are due to these properties. The alloy has good resistance to intergranular attack, pitting, crevice corrosion, impingement corrosion, and stress corrosion cracking due to chloride.
The alloy can withstand corrosive media that are both highly oxidizing and somewhat reducing. Similar to titanium grade 2, alloy 625 is particularly resistant to hot geothermal fluids. Inconel 625 round bar can tolerate a wide range of extremely corrosive situations thanks to its high alloy content.
Niobium works to stabilize the alloy against sensitization during welding, avoiding subsequent intergranular cracking. The high molybdenum percentage also makes this alloy particularly resistant to pitting and crevice corrosion.
Specification
The ASTM B 446/ASME SB-446 specification for alloy 625 bar includes a variety of shapes and sizes, including Inconel 625 round bars, rods, channel bars, T-bars, flat bars, blocks, square bars, triangle bars, threaded bars, profiles, half ingots, billets, and I/H bars.
Material must be provided in one of the following ways when considering wrought stainless round bars: hot-worked, hot-worked and annealed, hot-worked-annealed and cold worked, or hot-worked-annealed and heat treated.
Round bars can have a variety of surface finishes, including black, bright polished, rough turned, NO.4 finish, matte finish, BA finish, 2B, 2D, etc., depending on how they are treated, used, and applied.
Application
The skin of aircraft and spacecraft fuel tanks, among other heavy-duty uses, are formed from inconel 625 bar. These applications are found in the aerospace, military, and transportation product manufacturing industries.
Wide-ranging uses for Inconel Alloy 625 Bar can be found in the aerospace industry. These uses include bellows, submerged marine parts, aircraft ducting systems, engine exhaust systems, resistance-welded honeycomb structures for housing engine controls, fuel and hydraulic line tubing, and heat-exchanger tubing in environmental control systems.
