WEARTUF 500
Feature
WearTuf 500 is a full martensitic wear-resistant steel plate that has been quenched or quenched + tempered, with a typical Brinell hardness of 500 HBW. WearTuf 500 has very high wear resistance and good weldability and cold formability. Not only is the hardness very high, WearTuf 500 also has good impact toughness, ensuring that it has satisfactory crack resistance during manufacturing and use.
Application
WearTuf 500 is mainly used in mining, ore and recycling industries. Common uses include: heavy-duty mining trucks and dump trucks, buckets, shovel blades, breakers, crushers, sieve plates and various wear-resistant liner parts.
Size
WearTuf 500 Available thickness range is 4.0-50.0 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: 470-230HBW
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:
35J（-20℃），30J（-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.
