Stanhard 450 Abrasion Resistant Wear Plate Manufacturer & Supplier
Stanhard 450 is a low-alloyed quenched & tempered martensitic wear plate with a nominal hardness of 425-475 HBW. It combines abrasion resistance with the formability, weldability and toughness needed for fabricated wear parts. The workhorse wear grade — roughly twice the service life of Stanhard 400 in sliding abrasion.
