Hardox Wear Plate
Wear Plate adalah pelat tahan gesek yang dapat menahan keausan dan memiliki kekerasan khas sampai dengan 600 HB. Wear plate sangat cocok dipakai untuk aplikasi di mana ia terkena gesekan berat oleh mineral keras dan bahan abrasif lainnya.
Hardox Wear Plate bukan termasuk jenis material. Sampai saat ini wear plate itu tidak terdaftar di asosiasi standar internasional seperti ASTM, JIS atau DIN, kecuali wearplate dengan kandungan Mn 12%, digolongkan kedalam jenis material high manganese steel (Pelat Mangan).
Wear Plate hanya dikelompokkan berdasarkan kekerasannya, misal 400 HBN, 450 HBN dan 500HBN dan dari cara mereka diproduksi, dengan water quench [Hardox] dan oil quench [Creusabro]. Jadi masing-masing produsen memiliki merek mereka sendiri
