SSAB introduces new structural steel for lifting and advanced structures
by David Fleschen
Strenx 1100 Plus is a new hot-rolled, high-strength strip steel that accoridnt to SSAB possesses unique weld properties and delivers outstanding welding and bending performance. And thanks to its improved weld seam strength, it contributes to lighter, stronger and more environmentally friendly equipment with better performance in the transportation and lifting industries.
As the “Plus” in its name suggests, Strenx 1100 Plus offers customers something a bit extra. Traditionally, weld seams can represent weak links in the highest grades of structural steels. But with Strenx 1100 Plus such weld weaknesses are virtually eliminated because the strength, elongation and impact toughness properties of the welded area meet the minimum guarantees of the parent material. The optimal combination of strength and toughness of the welded and heat-affected area offers a major benefit to the design engineering process: the design can be based on the same minimum static strength for the entire application, depending on the design rules.
Strenx 1100 Plus is meant to be deal for lifting equipment, such as cranes, as well as lighter transportation solutions and advanced structures that require matching strength in the welds. It actually has higher strength than in the Stren® 1100 parent material. This translates into cranes that reach higher, trailers that carry more payload, and trucks that use less fuel and emit less CO2.
The product will be offered in thicknesses of 4.0-8.0 mm, widths up to 1,600 mm, and lengths up to 13,000 mm.
