    Incoloy 800H Fasteners Useful Information

    Inconel 800H is an iron-nickel-chromium alloy having sufficient resistance to carburization and oxidation at high temperatures as well as moderate strength. It is especially useful for high-temperature equipment in the petrochemical industry since the alloy doesn't form the embrittling sigma phase after long time exposure at 1200°F. Another important feature of Inconel 800H is excellent resistance to chloride stress-corrosion cracking.

    We produce premium quality Bolts from Nickel Alloys , Stainless Steels, Super Alloys, Duplex steels & Super Duplex, Copper & Copper Alloys with ASTM/ASME/DIN Standards & Specifications.We produce different types of hot forged cold formed bolts in almost all shapes & sizes.We also provide passivation, quality coating further processing as per client's requirement.Our Manufacturing Size ranges from M10 to M100 with varied length.
