WEARTUF 450
Feature
WearTuf 450 is a full martensitic wear-resistant steel plate that has been quenched or quenched + tempered, with a typical Brinell hardness of 450 HBW. WearTuf 450 wear-resistant steel plate also has good wear resistance, weldability and cold forming properties. Due to the high impact toughness, the steel plate has good crack resistance during manufacturing and use.
Application
WearTuf 450 can be widely used in various types of applications, such as muck transportation, mining industry and transportation equipment. WearTuf 450 can meet the needs of customers for lightweight design and application of equipment, such as road and off-highway dump trucks, mining dump trucks, open top containers, concrete mixer trucks and garbage collection trucks.
Size
WearTuf 450 can be supplied in a thickness range of 4.0-60.0 mm. Depending on the thickness of the steel plate, the width can reach 3100 mm and the length can reach 18000 mm.
Hardness guarantee value
Surface hardness: 425-475HBW
According to the standard EN ISO 6506-1, the surface Brinell hardness test is carried out after the surface of the steel plate is milled to a depth of 0.5-2.0 mm.
Minimum core hardness:
WearTuf abrasion-resistant steel plate is through-hardened, minimum core hardness is 90% of the guaranteed minimum surface hardness. *The core hardness is defined as the mean hardness over the plate central area, corresponding to 25% of the total thickness.
Typical value of impact toughness:
40J（-20℃），35J（-40℃）
Impact testing：The impact testing is performed in longitudinal direction to rolling for plate with thickness not less than 6 mm, according to EN ISO 148-1，average of three tests. For plate with thickness between 6 mm and 11.9mm，sub-sized Charpy V-specimens are used. The value of impact energy at -20℃ is listed on the product certificate.
