AR 450 abrasion resistant metal
AR450 ar steel is an abrasion resistant steel with a surface hardness of 420-470 durometer Brinell. AR450 abrasion resistant steel is a high carbon alloy steel consisting of several different elements such as carbon and boron.
The unique composition and treatment of AR450 abrasion resistant steel provides a higher surface hardness than AR400 ar plate steel, while maintaining good ductility, formability and impact resistance.
The AR450 abrasion steel we offer can be customised in size, cut, welded, punched and processed according to your end-use requirements for AR450 wear plate steel products.
