JF Bolts always uses pure and certified raw materials for manufacturing these bolts. These bolts are highly qualified for working in high heat temperatures. These Inconel bolts are available in various sizes, shapes, and thicknesses.

Inconel 718/825 Bolts

Inconel 718 bolts are highly used for industrial purposes. These bolts are made of nickel-chromium-iron elements. These elements are enriched with extraordinary properties. Bolts are nothing but threaded fasteners commonly being used for holding or joining two or more components together. Inconel 825 Bolts has some amazing properties such as excellent resistance from all types of chemical reactions. It provides excellent protection from erosion, rusting, and reduction. Inconel 718 bolts provide resistance from crevice corrosion, stress cracking, and oxidation, etc. Inconel 718 grade supports welding and pitting. It also has high tensile and yield strength.

825 Inconel Lock Bolts has similar properties to 718; In fact, this grade is slightly stronger than Inconel 718. Inconel 825 consists of a high amount of chromium, iron, and nickel. The combination also includes a moderate amount of copper, titanium, molybdenum, etc. Inconel 825 provides excellent resistance from phosphorus and sulfuric acids. It also provides excellent resistance from corrosion, stress cracking, and crevice corrosion. 718 Inconel Head Bolts can bear heat up to 1000°F. Inconel 825 bolts are commonly used in aerospace, petrochemicals, pharmaceutical and oil, gas purification, etc.
