Hastelloy G-30 Sheet (UNS N06030 / W.Nr. 2.4603)
High-strength corrosion-resistant alloy Plate Sheet for chemical and aerospace industry
As a leading supplier of Hastelloy materials in China, SEATHER TECHNOLOGY manufactures and supplies cost-effective Hastelloy® G-30® (UNS N06030) sheets with reliable quality and consistent performance.
Hastelloy G-30 is a nickel–chromium–iron alloy specifically designed to provide exceptional resistance to “wet process” phosphoric acid (Pâ‚‚Oâ‚…). Pâ‚‚Oâ‚… is a critical industrial chemical and the primary source of phosphorus used in agricultural fertilizers. This unique corrosion resistance makes Hastelloy G-30 sheet widely used in phosphoric acid processing and related chemical industries.
Hastelloy G-30 sheet is produced by cold rolling, flattening, and precision shearing of alloy coils. The typical thickness of cold-rolled Hastelloy G-30 sheet is below 5 mm, and compared with plate products, sheets feature a brighter and smoother surface finish.
In addition to excellent corrosion resistance, Hastelloy G-30 sheet offers high mechanical strength, good creep resistance over a wide temperature range, superior fatigue resistance, and excellent oxidation resistance, ensuring reliable performance in demanding service environments.
With strict quality control and efficient manufacturing processes, SEATHER TECHNOLOGY provides Hastelloy G-30 sheets that combine performance, durability, and cost efficiency for chemical processing, fertilizer, and other corrosion-critical applications.

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.
