SSAB launches Strenx 1100 Plus for stronger and lighter lifting equipment
STOCKHOLM, April 10, 2019 /PRNewswire-AsiaNet/ --

SSAB launches Strenx 1100 Plus for stronger and lighter lifting equipment 

SSAB today announced the launch of Strenx 1100 Plus strip steel. Available for 
immediate order, this new grade of hot-rolled, high-strength steel possesses 
unique weld properties and delivers outstanding welding and bending performance 
in booms, frames, cranes and other lifting equipment. 

Part of the 1100 MPa range of Strenx performance steels, Strenx 1100 Plus 
brings advances in weld seam strength that are ideal for the lifting sector. 
This new steel grade gives customers and end users lighter yet stronger 
equipment that can reach farther, increase payload and improve fuel economy. 
Strenx 1100 Plus is designed to help boost overall performance and productivity.

Weld weaknesses virtually eliminated

Traditionally, weld seams can represent weak links in the highest grades of 
structural steels such as S1100 and S900. 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 base 

Advanced, innovative design options

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. It is ideal for lifting equipments, 
and advanced structures that require matching strength in the welds. Strenx 
1100 Plus is designed for the applications that requires that requires welded 
joints; that we don't limit the heat input; this means they can weld at the 
room temperature compare to other high yield strength steel products in the 
market, lifting equipment producers can increase the productivity and reach 
more advanced design options

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 
-The recommended heat input interval is very wide, with cooling times, delta-T 
8/5, from 5 to 20 seconds. 
-Strenx 1100 Plus does not require any preheating when welded, based on CTS 
tests according to ISO 17642-2:2005. 
-Optimal combination of strength and toughness in welded area and heat affected 
Technical specifications - Reach higher and farther with Strenx 1100 Plus

See a sample and meet SSAB at Bauma Munich 2019
Visitors can find SSAB at Bauma Munich in Hall A6, Stand 423, to view samples 
of the new Strenx grade and place an order. SSAB is also happy to discuss 
results of its tests and analyses of the steel, provide advice on upgrading, 
and more.

Strenx 1100 Plus welded tensile test specimen
-Two pieces of 8 mm Strenx 1100 Plus have been welded together 
-MAG welded with a 960 MPa consumable with delta-T 8/5 of 12 seconds in 2 
-After the reinforcement been removed, the welded specimen was loaded in a 
tensile testing machine 
-The loading was stopped when the necking occurred 
-The necking shows where the sample would have broken if the loading hasn't 
been stopped 
-The rupture would have taken place in the unaffected parent material 
-It is the same minimum mechanical properties, yield, tensile and elongation, 
across a weld, as for the parent material
