Sumit Impex is the leading manufacturer and supplier of Inconel bolts in Inconel 600, Inconel 601 and Inconel 625. Our high temperature bolts are selected to be fabricated using high-quality nickel-chromium alloys because of their exceptional corrosion resistance and resistance to oxidation in the most demanding regimes. Our bolts are designed to show rock solid dependability whether being used in marine grade applications or parts used in the aerospace industry or in chemical processing. Our Inconel fasteners are also manufactured to ASTM B166, ASTM B564, ASME, and DIN standards but custom sizes and design of our fasteners can be provided to suit specific projects.
Inconel 600 bolts are manufactured in nickel-chromium alloy that has a high resistance to stress-corrosion cracking in chloride ions, acids and alkaline solutions. The tensile strength of such ASTM B166 Inconel bolts is approximately 655 MPa and therefore resistant to high temperature fasteners up to 1093 C (2000 F) which are suitable in furnace assemblies, heat exchangers, chemical processing plants and nuclear reactors. They are designed to the UNS N06600 specifications and have superb mechanical stability over a broad temperature range.
Sumit Impex is a Supplier of Inconel 600 Bolts, Biggest Stockist of Inconel Alloy 601/625 Bolts as per Standards in Mumbai, India.

Inconel 601 bolts offer superior oxidation resistance thanks to their aluminum-enhanced composition, making them the perfect choice for oxidation resistant bolts used in furnace components, gas turbines, and petrochemical equipment. These high-temperature Inconel bolts can operate continuously at temperatures of up to 1204°C (2200°F), with exceptional resistance to carburization and thermal stress. These bolts, which comply with UNS N06601 and ASTM B166/B564, are widely utilized in the thermal processing and heat treatment sectors.
Inconel 625 bolts are highly valued for their outstanding creep resistance, fatigue strength, and corrosion protection in harsh environments, including seawater and chemical media. These marine-grade Inconel bolts have a tensile strength of 930 MPa and are used in offshore engineering, aerospace systems, and chemical processing facilities. These marine-grade Inconel bolts have a tensile strength of 930 MPa and are used in offshore engineering, aerospace systems, and chemical processing facilities.
We provide a complete range of Inconel bolt types, including hex head bolts, socket head cap screws, stud bolts, U-bolts, anchor bolts, and threaded rods, with customizable choices for threading, coatings and head styles. These bolts are extensively used in industries such as aerospace and defense, marine and offshore engineering, power generation, petrochemical processing, and heat treatment equipment manufacturing.

Our Inconel 600, 601 and 625 bolts undergo thorough quality testing, which includes hardness tests, chemical analysis, tensile strength evaluation, non-destructive testing and dimensional inspections.
