Data sheet WELDOX:
WELDOX are high-strength structural steels with yield strength ranging from 420 to 1100 MPa. Their principle lies in achieving the given degree of strength while maintaining the best possible weldability. The result is for example WELDOX 700 with yield strength 700 MPa, which at 20 mm thickness has identical weldability as steel 11523.

  "ALLOYING WITH WATER" - we try to substitute some of the alloying elements necessary to achieve the required degree of strength by the intensity of the quenching process. Thus we achieve low values of carbon equivalent (Ce), which has a positive impact on weldability.

WELDOX 960

WELDOX as a material has contributed towards the revolution in the development of travelling cranes. By utilising the strength of these steels, the maximum load capacity of these cranes increased eight-fold without increasing their weight.
WELDOX 960 is in the largest models used for all load-bearing structures - the boom, the rotating mechanism, the undercarriage and the stabilising supports.
Each kilogram of weight saved reduces the dead weight and increases the crane's load capacity. Booms are manufactured according to stringent requirements on bendability, planeness and quality of the surface, which are exactly the properties which the WELDOX steels offer.



WELDOX 1100

It used to take a crew of sixty 10 hours to assemble a mobile bridge of a maximum span 30 m in the past. Meeting today's requirements, Karlskronavarvet AB has developed and built a very modern mobile bridge using the best steel available on the market - WELDOX 1100. It takes a crew of seven workers about 75 minutes to assemble the FB48 bridge. The span of the bridge is 46 metres without additional supports.



WELDOX steels are also available in versions marked D, F (e.g. WELDOX 700 D), where D means a guaranteed value of impact strength KV at -20°C, E means a guaranteed value of impact strength KV at -40°C and F at -60°C. It corresponds to EN 10137 coding Q or QL1 (e.g. S 690 QL).
