BlueScope has rejected an A$8.8 billion takeover bid from Steel Dynamics and SGH, which offered A$30 per share and proposed splitting the business, with Steel Dynamics taking North American operations and SGH retaining the rest. The board argued the offer undervalued assets including five North American businesses that delivered about 45% of FY2025 revenue, a steel mill in Ohio located roughly 130 km from a Steel Dynamics facility, and nearly 100 Australian sites generating A$6.95 billion in domestic sales. The decision comes amid 50% US steel import tariffs and BlueScope’s parallel interest in acquiring the Whyalla steelworks with partners Nippon Steel and Posco.

Researchers in Sweden have characterised how stainless steel corrodes in contact with liquid lead, providing data critical for structural components in lead‑cooled fast reactors proposed as alternatives to pressurised water designs. The work focuses on corrosion mechanisms at the steel–lead interface, including dissolution and oxide layer behaviour, which directly affect cladding integrity, vessel wall thickness allowances and inspection intervals. Findings are expected to inform material selection, allowable temperature windows and safety margins for future Generation IV lead‑cooled reactor projects.

Hillhouse Quarry Group, one of Scotland’s largest privately owned aggregates and asphalt producers, has appointed former NATS chief financial officer Alistair Borthwick as chief executive and promoted long-serving commercial director Mark Munro to managing director. The leadership change follows the planned April retirement of managing director Robert McNaughton, who led the family-run business for 18 years as it expanded from an Ayrshire quarry operator into a national group and entered Scotland’s top 100 private companies. For contractors and materials buyers, the move signals continuity in long-term supply relationships and pricing strategy, with added financial discipline from Borthwick’s infrastructure background.
