When fertilizer and phosphoric acid producers faced catastrophic corrosion challenges in their concentration operations, the introduction of Hastelloy G30 Sheets revolutionized reliability and operational uptime. Aurico Alloys LLP supplies these specialized sheets to chemical, oil & gas, marine, pharmaceutical, and power generation industries, enabling engineers and procurement teams to specify material that endures where ordinary alloys fail.

Hastelloy G30 (UNS N06030, DIN 2.4603, ASTM B582) is a nickel-chromium-iron alloy engineered specifically for resistance to "wet process" phosphoric acid—an industry-critical application processing millions of tons annually for agricultural fertilizers. Its high chromium content delivers outstanding oxidation resistance to nitric acid and mixtures, while molybdenum and copper provide moderate resistance to reducing acids like hydrochloric and sulfuric. The alloy's structured composition resists grain boundary precipitate formation, enabling robust welded service.
Aurico Alloys LLP offers Hastelloy G30 Sheets in comprehensive size ranges and finishes, fully certified to ASTM and ASME standards with mill test certificates and traceability. Our proven inventory enables rapid fulfillment for OEM fabrication, equipment maintenance, and new industrial projects globally.
Choosing Aurico's Hastelloy G30 Sheets ensures equipment longevity, reduced corrosion costs, and compliance with strict industrial safety and quality standards in acid processing and chemical manufacturing.
High-quality Hastelloy G30 Sheets ready for industrial use.

Applications & Benefits
Why this grade
Hastelloy G30 carries about 30% chromium and is stabilised with niobium. It was developed for phosphoric acid and remains the usual choice for wet-process phosphoric acid and fertiliser plant, as well as for mixed acid streams containing nitric and hydrofluoric acid.
- Wet process phosphoric acid evaporators and concentration equipment—primary industrial use
- Nitric acid processing and pickling operations
- Chemical reactors and heat exchangers in oxidizing environments
- Oil & gas refinery and petrochemical processing equipment
- Fertilizer manufacture and agrichemical production
- Nuclear fuel reprocessing and nuclear waste processing systems
