SSAB is launching Strenx 1100 Plus strip steel, which is a hot-rolled, high-strength steel possessing unique weld properties that delivers “outstanding” welding and bending performance, the company said.
Thanks to advances in weld seam strength, the new strip steel, which is part of the 1100 MPa range of Strenx performance steels, contributes to lighter, stronger equipment in the lifting and transportation sectors.
“We’re thrilled to be introducing Strenx 1100 Plus to the booming (Asia-Pacific) region and beyond,” said Magnus Carlsson, Strenx product manager at SSAB. “We believe (this product) simply can’t be beat on the market today for any high-performance applications that can benefit from matching strength in the welds.
“We look forward to continuing to serve markets that quickly develop in advanced designs and technology … and to apply SSAB’s innovations in steel technology to the challenges facing the lifting and transportation sectors.”
Traditionally, weld seams often are weak links in the highest grades of structural steels, SSAB said. But with Strenx 1100 Plus, weld weaknesses are “virtually eliminated” because the strength, elongation and impact toughness properties of the welded area meet the minimum guarantees of the base material. The combination of strength and toughness of the welded and heat-affected area benefits the design because it can be based on the same minimum static strength for the entire application, depending on the design rules.
The company says Strenx 1100 Plus is ideal for lifting equipment, such as cranes, as well as lighter transportation solutions and advanced structures that require matching strength in the welds. It boasts higher strength than in the Strenx 1100 base material, translating into cranes that reach higher, trailers that carry more payload, and trucks that use less fuel and emit less CO2.
Strenx 1100 Plus benefits in the workshop:
- An exceptionally clean steel and a precisely controlled production process mean consistently high quality and predictable results
- Guaranteed flatness, thickness, bendability
- Tight tolerances, guaranteed
- Welding can be done at room temperature (based on CTS tests according to ISO 17642-2:2005)
- Optimal combination of strength and toughness in welded area and heat affected zone
