Stronger structural steel welds and
bends easily
An ultra-high strength, hot-rolled structural steel strip, having a minimum yield strength of 1200MPa, is easy to bend and weld and has good paint adherance finish.
Domex 1200SSAB Tunnplat has launched what it claims to be the 'world's ultimate' ultra-high strength, hot-rolled structural steel from strip Domex 1200 will allow stronger structures in applications such as cranes, containers and heavy vehicles

The steel will be unveiled at the ESEF 2008 exhibition in Utrecht, The Netherlands, on March 11-14.
The Domex 1200's minimum yield strength of 1200MPa sets a new standard for ultra-high strength structural steels from strip, said SSAB to manufacturingtalk.com.
The new steel has been developed for use in slender structures that must be capable of withstanding very high stresses.
Product manager for Domex at SSAB Tunnplat, Berit Arvidsson, said: "The outer ends of crane booms and the top profiles of dumper truck bodies are a couple of typical examples for which Domex 1200 is very well suited.
We have tested the steel together with some of our customers during the development process, and we are now building up a knowledge bank for the new steel.
We have begun studies for various applications and we expect to be able to offer support to our customers in the form of knowledge, service and support, to enable them to draw maximum benefit from this steel in their products".
* Easy to bend and weld - in addition to the high strength, a further characteristic of Domex 1200 is its good surface finish.
"The surface has low topography, which means that it is very smooth," said Arvidsson.
"The benefit is that it is easier to achieve good painting results, and that the surface friction is low, which is beneficial in telescopic cranes".
The steel also has good machining properties, and is well suited for bending and welding.
In spite of the high strength, the steel can be bent to tight radii.
"The material has a low content of alloying elements, is very pure, and is produced in a meticulously controlled process," said Arvidsson when explaining the properties of the steel.
"This steel consolidates our position as world leader in hot-rolled, ultra-high strength steels from strip".
Domex 1200 will be available in a strip width of 1500mm and in thicknesses of 4-8mm.
SSAB has produced a wide range of test sheets that can be ordered in various fixed lengths of between 3m and 12m.
