Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Inconel Alloy 625 Bolts And Nuts, which is superior to many other high temperature alloys under cyclic heating and cooling conditions. Inconel 625 Hex Head Bolts are often used in resistance – welded honeycomb structures for housing engine controls, fuel and hydraulic line tubing. Inconel 625 Hex Head Nuts has excellent seawater pitting and crevice corrosion resistant, where they form a disk – shaped morphology and are coherent with respect to the matrix. In alkaline, fresh water, salt water, neutral salts, and in the air, almost no attack occurs in Inconel 625 Square Bolts.
Typical Applications for Inconel 625 Square Nuts include: chemical process equipment handling mixed acids both oxidizing and reducing. Inconel 625 U-Bolts resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion. Inconel 625 Lock Bolts can be easily welded and processed by standard shop fabrication practices. Inconel 625 Eye Bolts has almost complete freedom from chloride induced stress corrosion cracking.
Inconel 625 Eye Nuts is also used in Reaction vessels, Furnace hardware, Heat exchangers, Gas turbine engine duct work, Sour gas production tubes, Equipment used to produce acid and so on. These Inconel 625 T-Bolts is a nickel – chromium – molybdenum alloy with an addition of niobium that acts with the molybdenum to stiffen the alloy’s matrix and thereby provide high strength without a strengthening heat treatment.
