The high chromium content (approximately 30%) in Inconel 690 Round Bar significantly improves its resistance to oxidizing agents and aqueous corrosion, particularly in hot acidic solutions. The alloy also offers excellent resistance to stress corrosion cracking and crevice corrosion. It is extensively used in steam generators, nuclear reactor tubing, and components exposed to flue gas environments. Labdhi Metals supplies these bars in solution-annealed condition with precise tolerance and surface finish.
Manufactured in accordance with ASTM B166, the round bars are available in both hot-rolled and cold-drawn forms, with various lengths and diameters to suit diverse industrial needs. Labdhi Metals provides Inconel 690 Round Bars with surface finishes such as black, bright, and centerless ground, ensuring superior machinability and dimensional accuracy. Each product is subject to rigorous quality checks including ultrasonic testing, mechanical testing, and chemical composition analysis.
Labdhi Metals offers complete traceability and documentation for its products, including Mill Test Certificates (EN 10204 3.1/3.2), Positive Material Identification (PMI), and third-party inspection reports. The bars are carefully packed to prevent damage during transit and are available with custom machining services on request. Their high-performance and low-maintenance nature make these bars an ideal choice for critical operations in aggressive conditions.
