WearTuf 450 Abrasion Resistant Steel Plate

Characteristics
WearTuf 450 is a fully martensitic Q&T abrasion resistant steel having a hardness of average 450 Brinell. WearTuf 450 combines wear resistant properties with excellent weldability and cold forming capability. Due to the high impact toughness, WearTuf 450 offers very good crack integrity.

Dimensions
WearTuf 450 is supplied in the thickness rage of 3.0 - 60.0 mm and in the plate width of 900 – 3 100 mm. Supplied plate length from 4 000 to 18 000 mm.

Impact toughness
Typical 45J/-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 longitudinal direction to rolling, according to EN ISO 148-1.

Hardness guarantee
Surface hardness: 425-475 Brinell
Guaranteed hardness range, measured on a milled surface at a depth of 0.5 – 2.0 mm below the plate surface, according to ISO EN 6506-1.
Min center hardness:
Plate thickness ≤ 20mm: min 425 Brinell
Plate thickness ＞ 20mm: 95% of min guaranteed surface hardness.

Applications
WearTuf 450 fits a vast number of different applications within earth moving, mining and transport equipment. WearTuf 450 is specially designed for applications focusing on light weight design concepts, such as on and off road dumper and tipper bodies, open top containers, concrete mixer and garbage trucks.

Ultrasonic testing
All plates delivered meets the Class E1, S1 requirement, according to EN 10 160.

Delivery condition
WearTuf 450 is delivered in the as quenched (Q) condition, and when found necessary in the condition of quenched and tempered (QT).
The plates are delivered with sheared or thermally cut edges.

Tolerances
The thickness tolerances of WearTuf 450 meets and exceeds the thickness tolerance of EN 10 029
Class A . Tolerances on shape, length, and width meets the requirements of EN 10029. Flatness tolerances conforms to EN 10 029 Class S or closer. 

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
Since the properties in the as delivery condition cannot be retained after exposure at service temperatures above 250°C, WearTuf 450 is not intended for further heat treatment.
