Characteristics

LiftHi 1100 is a fully martensitic Q&T ultra high strength structural steel plate.LiftHi 1100 provides a very good weldability and is well suited for cold forming operations.

Applications

LiftHi 1100 is used in various types of lifting appliances such as mobile and truck crane boom sections and other types of outriggers.

Dimensions

LiftHi 1100 is supplied in the thickness range of 4.0-12.0 mm and in plate width of 900-3 100 mm and in plate length from 3000 to 18000 mm.

TENSILE PROPERTIES

Uniaxial tensile testing is performed in the transverse direction to rolling according to EN ISO 6892-1.

IMPACT TOUGHNESS

The impact toughness is given as absorbed energy at temperature being the Min 27J/-40°C(-40 °F) average of three full size Charpy-V test samples in transverse direction to rolling, according to EN ISO 148-1(*)

CHEMICAL COMPOSITION

Ladle analysis: The steel is grain refined and fully killed,wt%

ULTRASONIC TESTING

All plates delivered meets the Class E2, S2 requirement,according to EN 10160.

DELIVERY CONDITION

LiftHi 1100 is delivered as quenched and tempered (QT).(Q: according to EN 10O25-6). The plates are delivered with sheared or thermally cut edges.

TOLERANCES

The thickness tolerances of LiftHi 1100 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 EN10029 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 1100 is not designed for applications requiring working or service temperatures above 200°C. If exceeding this temperature, the mechanical properties of the steel can no longer be guaranteed.

PROCESSING PERFORMANCE

More information on the steel processing perfor-mance of LiftHi 1100 can be found by consulting the LiftHi 1100 Technical manuals on 1)Bending, 2)Welding, 3)Cutting and 4)Machining.
