Inconel 625 Round Bar

ASTM B446 625 Inconel Round Bar Stockist in Mumbai India. ASTM B446 625 Hex Bar, Flat Bar, Forged Bar, Square Bar Alloy 625 Bright Bar Stockist and Supplier in Mumbai India.


Inconel 625 round bar is a solid cylindrical metal bar made from a nickel-chromium-molybdenum-niobium alloy. This high-strength material resists extreme heat and corrosion, making it reliable for tough industrial uses. The molybdenum and niobium in its composition give it strength without requiring any heat treatment. It holds integrity in extreme environments and resists stress cracking. Preston Pipes and Alloys offers high-quality Inconel 625 round bars with consistent chemical and mechanical properties. The alloy contains a minimum of 58% nickel, 20–23% chromium, 8–10% molybdenum, and up to 5% iron. With a melting point of 1290–1350°C and a density of 8.44 g/cm³, these bars meet ASTM mechanical requirements for flanges and fittings with excellent tensile and yield strength.


Inconel 625 round bars perform well in saltwater, making them ideal for marine uses like wire ropes, propeller blades, and underwater cable sheathing. They handle salt exposure without corroding, even at high temperatures. These bars are essential for parts exposed to heat and harsh chemicals in the oil and gas sector. They're used in drilling rigs and pipelines where strength and resistance are critical. In high-performance cars Inconel 625 rods appear in exhaust systems and ignition parts. Their strength-to-weight ratio and heat resistance improve performance. This alloy is also used in industrial parts washers especially in coastal factories exposed to salty air. Inconel 625 round bar stockist options serve to every sector with reliable supply and ready stock.


Inconel 625 Round Bar

We supply Inconel 625 round bars in sizes ranging from 15NB to 150NB. Extrusion and cold drawing are two manufacturing processes that produce bars with precise dimensional tolerances. Surface finishes vary from polished and bright-drawn to hot-rolled and sand-blasted. The bars are also available in flat, hex, square and wire forms. With flexible specs, customers can choose the right type for their application needs. As an experienced Inconel 625 round bar manufacturer, we ensure consistency in finish, size, and performance.


Each Inconel 625 round bar undergoes thorough testing, including ultrasonic inspection, PMI testing, hardness, and tensile strength checks. We follow strict quality control at every stage—from raw material selection to final dispatch. Bars are packed in strong wooden boxes, wrapped in waterproof material, and labeled with complete details to ensure safe transit. As trusted Inconel 625 round bar suppliers, we meet global standards for packaging and testing, assuring our clients of dependable service and consistent product quality.
