Inconel Fasteners

Inconel Fasteners Manufacturer, Supplier & Stockist in India

Unifit Fastener Company is a reputable manufacturer of high-performance Inconel fasteners in India, which provides the best and most precise solutions to high industrial operations. The grades which we cover are Inconel 600, 601, 625, 686, 718 and 725, and these grades are designed to provide outstanding strength and stability under extreme temperature conditions and when exposed to corrosive conditions.

Inconel is a nickel-chromium-molybdenum alloy that is commonly referred to as having excellent oxidation resistance, chloride stress-corrosion cracking, and high-temperature creep. This will make our Inconel bolts, nuts, studs, washers and threaded rods perfect for construction work where the environment is aggressive in nature and conditions such as gas turbines, chemical processing units, marine systems, heat-treatment equipment and deep-sea drilling operations are present.

Unifit Fastener manufactures each product by use of high quality raw materials and quality control to attain correct dimensions, high durability and long service life. Our Inconel fasteners have a stability range from cryogenic temperatures up to very high temperatures close to 982°C and are a stable product where standard stainless steel grades cannot be used.

Our fasteners are available in several sizes, shapes and specifications to order, and they can be used in a variety of applications and perform consistently regardless of the high mechanical load. We provide reliable Inconel fastening solutions at a reasonable price, whether it is the offshore hardware that needs to be corrosion-proof or the offshore high-temperature fittings that need the high-temperature fittings to be made of power and petrochemical plants.

Frequently Asked Questions About Inconel 600 Fasteners

What are Inconel studs?

Inconel studs are high-strength, nickel-chromium alloy fasteners designed for extreme environments with high temperature and corrosion. They are commonly used in aerospace, chemical, and marine industries for durable, vibration-resistant connections.

What are Inconel bolts?

Inconel bolts are industrial fasteners made from nickel-based superalloys, known for excellent resistance to heat, corrosion, and oxidation. They maintain strength in harsh conditions like chemical plants, gas turbines, and marine applications.

Who is the manufacturer of Inconel fasteners in India?

Unifit Fastener is a leading manufacturer and supplier of Inconel fasteners in India, offering a wide range of Inconel bolts, nuts, screws, washers, and studs that comply with international standards such as ASTM and ASME. They serve critical industries including aerospace and chemical processing.

Is Inconel better than titanium?

Inconel excels in high-temperature and corrosive environments with superior oxidation resistance, while titanium offers a better strength-to-weight ratio and flexibility. Both alloys serve specialized applications based on environmental and mechanical demands.

What is the best coating for Inconel fasteners?

Electroless nickel plating is often considered the best coating for Inconel fasteners due to its uniform corrosion resistance, hardness, and wear protection. Other options include chrome plating and cadmium plating for enhanced durability in severe conditions.
