Inconel Bolts

Inconel Bolts belong to the family of nickel-chromium-molybdenum alloy. These bolts are made up of a material known as a Ni-Cr alloy which provides excellent strength, high corrosion resistance, and the ability to perform in extreme environments. Inconel bolts can endure service temperatures ranging from cryogenic levels to 2200°F (982°C). Available in different types, shapes, such as hex bolts, socket head bolts, heavy hex bolts, U-bolts, J-bolts, carriage bolts, flange bolts, eye bolts to satisfy varied industrial applications. These nickel-chromium alloy fasteners are utilized in the aerospace, marine, oil and gas, and chemical industries where dependability is critical.

What is the price of Inconel Bolts?

The inconel bolts price in India usually range between ₹150 to ₹800 per piece. The inconel bolts cost range from ₹3,000 to ₹3,500 per kg for standard grades. The price changes depending on size, grade, and market conditions. Higher cost is due to its unique properties, but quality makes them worth it for critical projects.

Common Inconel Bolt Grades

Inconel bolts are available in many grades, each having its own strength and resistance levels. Below are the most widely used grades:

Inconel 600 Bolts/Screw (UNS N06600)

Inconel 600 is a nickel-chromium alloy containing about 72% nickel, 14–17% chromium, and small amounts of iron. It provides good carburization and oxidation resistance through 2000°F (1093°C). With a tensile strength of around 655 MPa, these bolts are used in furnace components and chemical processing.

Inconel 601 Bolts/Screw (UNS N06601)

Inconel 601 is a nickel-chromium alloy with added aluminum. The aluminum addition enhance oxidation resistance, making it highly stable through 2200°F (1204°C). It has a tensile strength of about 550 MPa and is commonly used in heat-treating equipment and thermal processing.

Inconel 625 Bolts/Screw (UNS N06625)

Inconel 625 is made up of 58% nickel, 20–23% chromium, 8–10% molybdenum, and 3.15–4.15% niobium. It offers outstanding resistance to oxidation up to 1800°F (982°C) and excellent strength with a tensile strength of 930 MPa. These bolts are used in aerospace, marine, and chemical industries.

Applications of Inconel Bolts

Inconel bolts are used in 7 major sectors due to their strength and resistance, they are as follows:

Chemical Processing Plants: Used in reactors, heat exchangers, and piping systems which deal with corrosive acids and chemicals.
Aerospace: Essential in jet engines, turbine blades and exhaust systems where high temperature stability is required.
Marine Industry: These bolts are installed in shipbuilding, offshore rigs, and seawater equipment due to saltwater corrosion resistance.
Oil & Gas: Used in drilling rigs, pipelines, and subsea operations where pressure and heat resistance is vital.
Electronics: Used in semiconductor equipment and precision connectors due to its non-reactive and steady characteristics.
Nuclear Industry: Inconel bolts are used for reactor vessels, control rods, and fuel handling systems.
Power Generation: Applications include gas turbines, boilers, and steam generators, which require great heat and stress tolerance.

Manufacturing Process of Inconel Bolts

Our manufacturing process of inconel bolts involve 8 steps to ensure they meet performance standards. Each stage improves strength, durability, and accuracy.

Raw material selection: Premium Inconel alloy is used to ensure strength and corrosion resistance.
Cutting: The chosen raw material is cut into precise lengths, preparing the blanks for further processing.
Hot/Cold Forging: Bolt heads are formed by forging, which gives them strength and an accurate shape for their intended use.
Thread Rolling: Threads are rolled instead of cut which improve tensile strength and create uniform threading.
Heat Treatment: Bolts go through heat treatment to improve hardness, toughness and overall mechanical performance.
Surface Treatment: Coatings such as passivation, galvanization or plating are used to improve corrosion resistance.
Inspection and Testing: Each bolt is tested for dimensions, surface quality, tensile strength, and durability.
Packaging and Dispatch: Following quality inspections bolts are carefully packaged and dispatched to clients all over the world.

Key Characteristics of Inconel Bolts

Inconel nickel alloy bolts provide reliable performance in extreme conditions. Their qualities make them ideal for essential applications.

High Temperature Stability: These bolts maintain their strength and structure at temperatures up to 2200°F.
High Corrosion Resistance: They are resistant to oxidation, acids, and harsh chemicals, making them perfect for demanding applications.
High Strength: Inconel bolts have high tensile strength, allowing them to sustain huge loads without bending or failing.
Stress Corrosion Cracking Resistance: Inconel nickel alloy bolts resist cracking under tension and exposure to chloride or acidic solutions.
Service Life and Versatility: Long-lasting performance across industries reduces maintenance and replacement needs.
Higher Mechanical Properties: Their strong combination of hardness, toughness and durability exceeds many common alloys.
