In 2023–2024 global infrastructure programs installed more than 5 million kilometers of pipeline. Ductile cast iron pipes accounted for over 51 % of those installations, driven by municipal water systems and wastewater upgrades . The volume of ductile iron pipes installed reached 8 million tonnes in 2023. The continuous tube market alone was valued at USD 211 million in 2024 . Public funding of USD 200 billion was allocated for waterworks in Asia Pacific in 2024, reinforcing demand. Growing environmental regulations require corrosion-resistant ductile iron, increasing average pipe life to 100 years compared to alternatives at 50 years, thus supporting higher volume installations.

RESTRAINT

High energy and raw‑material costs

In 2023, electricity represented 25 % of ductile iron foundry costs; coke and scrap iron made up 40 %, with scrap iron prices rising 30 % year-over-year. These increases led to average production cost per tonne climbing from USD 550 to USD 715. Geopolitical tensions in 2022–2024 disrupted iron ore supply, pushing ore prices above USD 120 per tonne, increasing input costs for grey and ductile foundries. Foundries in Europe reported operating at 70 % capacity versus 90 % in 2022 due to cost pressures. These conditions slowed project procurement cycles and pipe production volumes fell 8 % YoY in Europe.

OPPORTUNITY

Surge in electric‑vehicle and automotive casting demand

Automotive castings accounted for 28 % of ductile and grey iron output in 2024 . Within ductile iron components, engine block and gearbox housing demand rose 20 % in 2023 due to EV adoption . EV vehicle sales increased 35 %, projecting network up to 50 % by 2025. Ductile cast iron offers vibration dampening and heat resistance essential for EV powertrain. Foundry capacity in India rose by 15 % in 2024 to cater to automotive OEMs. Over 30 new EV foundry lines were commissioned in Asia Pacific in the same year. This trend opens high‑value casting opportunities such as brake rotors, chassis components, and structural supports.
