SSAB has started building a new quenching line at Oxelösund in Sweden. The SEK 3.3 billion project adds about 100,000 tonnes a year of capacity for wear-resistant and protection plate such as Hardox and Armox, with production planned for 2030.
What happened
SSAB marked the start of construction on 13 October 2026 (SSAB release). The investment was first announced in May 2026.

Advertise with Loharo- Quenching cools hot plate very quickly to make it hard and strong. It is the key step for SSAB’s most advanced wear and protection grades.
- The new line will add roughly 100,000 tonnes a year of capacity for SSAB Special Steels’ highest-value products.
- SSAB says the line uses modern electrified technology and is being built while the company finishes converting the Oxelösund mill.
- Target markets named in the release include demanding industrial, safety and defence-related uses.
Production is planned to start in 2030.
Why it matters for steel buyers
Quenched and tempered plate is a niche, but supply is tight. Buyers in mining, earthmoving, trucks and defence often face long lead times for Hardox-type and armour grades. Another 100,000 tonnes from a European producer should ease that, though not before 2030.
The project also shows where European mills see their margins: in hard-to-copy premium plate, not commodity coil, where imports compete on price. With EU defence spending rising, protection steel is a growing segment. For context on plate supply, see our Q4 2026 European steel outlook.
What to watch
- Whether Oxelösund’s conversion to electric steelmaking stays on schedule, as it supplies the steel for the new line.
- Lead times and pricing for wear and protection plate until 2030.
- Similar quenching or heat-treatment investments by other European plate mills.
