LiftHi 700 is a fully martensitic Q&T extra high strength structural steel. LiftHi 700 complies with S690QL,according to EN10025-6, but offers closer overall tolerances, improved impact toughness and work shop performance. Due to the lean composition of LiftHi 700 the weldability stays extremely good along with cold forming capability.
The applications segments in which LiftHi 700 are most frequently found is within truck chassis, outriggers, various lifting and handling equipment.
LiftHi 70O is supplied in the thickness range of 4.0 -50.0 mm and in plate width of 900-3 100 mm. Supplied plate length from 4 000 to 18 000 mm.
|700 MPa||780-930 MPa||14%|
Uniaxial tensile testing is performed in the transverse direction to rolling according to EN ISO 6892-1.
The impact toughness is given as absorbed energy at temperature being the average of three full size Charpy-V test samples in transverse direction to rolling, according to EN ISO 148-1(*)\
Ladle analysis: The steel is grain refined and fully killed, wt%

All plates delivered meets the Class E1, S1 requirement,according to EN 10160.
LiftHi 70O is delivered as quenched and tempered (QT).(Q:according to EN 10025-6).
The plates are delivered with sheared or thermally cut edges.
The thickness tolerances of LiftHi 700 meets and exceeds the thickness tolerance of EN 10029 Class A(**). Tolerances on shape, length and width meet the requirements of EN 10029.Flatness tolerances conforms to EN 10029 Class S,or closer.For more information, consult the Leong Jin catalogue: General Product Information.
Surface condition and properties
The delivered surface finish meets and exceeds that of EN 10163-2 Class A Subclass 3.
The plates will be delivered as painted, using a low zinc silicate corrosion protective shop primer. Plates can also be delivered as unpainted.
LiftHi 700 is not designed for applications requiring working or service temperatures above 550°C. lf exceeding this temperature, the mechanical properties of the steel can no longer be guaranteed.
