Hastelloy G30 Products

Hastelloy G30 Products Supplier – Exotic Metals LLP

Hastelloy G30 is a high-performance nickel-molybdenum alloy enhanced with tungsten, engineered for superior corrosion resistance in aggressive reducing acid environments, such as hydrochloric acid, sulfuric acid, and mixed acid solutions. Compared to earlier G-series alloys, G30 offers improved weldability, higher strength, and excellent thermal stability, making it ideal for chemical reactors, pickling tanks, heat exchangers, and industrial piping systems. Exotic Metals LLP supplies Hastelloy G30 in diverse forms and custom-fabricated products, ensuring reliability in the most demanding chemical and industrial applications.
