Product Description

Inconel 625 N06626 high strength, excellent workability, good weldability and excellent corrosion resistance

INCONEL 625 is a widely used grade among the Inconel series nickel alloys, and it is also a superior product of Xunshi New Material. Xunshi provides Inconel 625 products with rich shapes and complete specifications, and various customized products according to different standards and specifications are available from us. The Inconel 625 product form supply of Xunshi New Materials includes round rods, laths, wires, wires, Rods, hot-rolled plates, cold-rolled plates, strips, profiles, welded pipes, seamless pipes, capillary tubes, forgings, pipe fittings, flanges, fasteners, welding wire, welding rods and 3D printing powder, etc.

Inconel 625 is widely used due to its high strength, excellent workability, good weldability and excellent corrosion resistance. Its operating temperature range can cover cryogenic temperatures to 1800°F (982°C).

The strength of INCONEL 625 alloy is generated by the hardening effect of molybdenum and niobium in the nickel-chromium matrix, so the alloy does not require precipitation hardening. This combination of elements is also the reason why the material is super corrosion-resistant in many highly corrosive environments and resistant to oxidation and carburization in high-temperature environments.

Corrosion Resistance

Aqueous Corrosion

The high alloy content of INCONEL alloy 625 enables it to withstand a wide variety of severe corrosive environments. In mild environments such as the atmosphere, fresh and sea water, neutral salts, and alkaline media there is almost no attack. In more severe corrosive environments the combination of nickel and chromium provides resistance to oxidizing chemicals, whereas the high nickel and molybdenum contents supply resistance to non-oxidizing environments. The high molybdenum content also makes this alloy very resistant to pitting and crevice corrosion, and niobium acts to stabilize the alloy against sensitization during welding, thereby preventing subsequent inter-granular cracking. Also, the high nickel content provides freedom from chloride ion stress corrosion cracking.

This combination of characteristics makes INCONEL alloy 625 useful over a broad spectrum of corrosive conditions. For instance, it has been recommended as a material of construction for a storage tank to handle chemical wastes, including hydrochloric and nitric acids - chemicals which represent directly opposite types of corrosion problems. Materials which resist either one of these acids are normally severely attacked by the other.

INCONEL alloy 625 has good resistance to oxidation and scaling at high temperature.
