LIFTHI 900
Characteristics
LiftHi 900 is a fully martensitic Q&T ultra high strength structural steel plate.LiftHi 900 complies with S890QL,according to EN 10025-6, but offers close overall tolerances and excellent work shop performance.LiftHi 900 provides a very good weldability and is well suited for cold forming operations.
Applications
LiftHi 900 is commonly used in various types of lifting appliances,concrete pump truck boom sections,outriggers and heavy truck chassis.
Dimensions
LiftHi 900 is supplied in the thickness range of 4.0-30.0 mm and in plate width of 900-3100 mm and in plate length from 3000 to 18000 mm.
TENSILE PROPERTIES
| Yield | Tensile | Elongation strength |
| strength | strength | |
| Rp0.2,min | Rm | A5, min |
| 900 MPa | 940-1100 MPa | 12% |
Uniaxial tensile testing is performed in the transverse direction to rolling according to EN ISO 6892-1.
IMPACT TOUGHNESS
Min 70J/-40℃C (-40°F) 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 (*)

ULTRASONIC TESTING
All plates delivered meets the Class E2, S2 requirement,according to EN 10160.
DELIVERY CONDITION
LiftHi 900 is delivered as quenched and tempered (QT).(Q:according to EN10025-6). The plates are delivered with sheared or thermally cut edges.
TOLERANCES
The thickness tolerances of LiftHi 90O 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.
HEAT TREATMENT
LiftHi 900 is not designed for applications requiring working or service temperatures above 550°C. If exceeding this temperature, the mechanical properties of the steel can no longer be guaranteed.
PROCESSING PERFORMANCE
More information on the steel processing performance of LiftHi 90O can be found by consulting the LiftHi 900 Technical manuals on 1)Bending,2)Welding, 3)Cutting and 4)Machining.
