The global nickel alloy market, including our Inconel 625 (GH3625) coils, was valued at USD 1.2 billion in 2023 and is projected to reach USD 1.8 billion by 2032, growing at a CAGR of 5.3%. The petrochemical industry is a major driver, as it faces increasing demands for materials that can withstand aggressive acids, high temperatures, and corrosive gases. Sustainability trends are pushing companies toward durable, low-maintenance materials to reduce waste and operational costs, and our coils are a perfect match.
Petrochemical plants rely on Inconel 625 for its ability to resist acids like sulfuric and hydrochloric in reactors, heat exchangers, and pipelines. The oil and gas sector, dealing with sour gas and chloride-rich environments, also leans heavily on this alloy for offshore and onshore applications. Emerging trends in renewable energy, such as geothermal plants, and stricter regulations in pollution control are boosting demand for high-performance alloys. Aerospace and power generation industries further benefit from Inconel 625’s durability in high-temperature, corrosive conditions.
As the petrochemical industry moves toward harsher environments and stricter environmental standards, our Inconel 625 coils stand out. Their corrosion resistance and high-temperature stability make them a go-to choice for applications where reliability and efficiency are critical, ensuring cost savings over time.
