Hastelloy G-30 Welded Pipe Tube (UNS N06030 / W.Nr. 2.4603)
High-strength corrosion-resistant alloy pipe tube for chemical and aerospace industry
As a leading Chinese manufacturer and supplier of Hastelloy piping products, SEATHER TECHNOLOGY manufactures Hastelloy® G-30® (UNS N06030) welded pipes and tubes in a wide range of sizes to meet diverse industrial requirements.
Hastelloy G-30 is a nickel–chromium–iron alloy specifically developed for excellent resistance to “wet process” phosphoric acid (Pâ‚‚Oâ‚…), one of the most important industrial chemicals and the primary source of phosphorus used in agrichemical fertilizers. In addition, the alloy offers reliable performance in other corrosive chemical environments, making it well suited for fertilizer, chemical processing, and related industries.
Hastelloy G-30 welded pipes and tubes are produced by precision forming and welding of high-quality Hastelloy G-30 strip or plate. As the performance of welded products is highly dependent on raw material quality, SEATHER TECHNOLOGY sources materials exclusively from reputable large-scale mills. Combined with advanced slitting, forming, and welding technologies, this ensures excellent weld integrity, dimensional accuracy, and consistent material properties.
For applications with higher corrosion resistance and structural uniformity requirements, solution annealed Hastelloy G-30 welded pipes and tubes are available. SEATHER is equipped with in-line solution annealing facilities, enabling us to deliver products that meet more demanding service and specification requirements.
With strict quality control and mature manufacturing expertise, SEATHER TECHNOLOGY provides reliable Hastelloy G-30 welded pipe and tube solutions for phosphoric acid service and other severe industrial environments.

What is Hastelloy G-30 (UNS N06030)
Alloy G-30 also referred to as the UNS N06030/W.Nr. 2.4603 alloy.
Alloy G-30 is a nickel-chromium-iron material highly resistant to “wet process” phosphoric acid.
As a result of its high chromium content, G-30 alloy is also very resistant to other oxidizing acids, such as nitric, and mixtures containing nitric acid. It possesses moderate resistance to reducing acids, such as hydrochloric and sulfuric, as a result of its appreciable molybdenum and copper contents.
Alloy G-30 is widely used in reactors and heat exchangers.
Alloy G-30 is available in the form of plates, sheets, strips, billets, bars, wires, pipes, tubes, and covered electrodes.
