Stanhard 400 Abrasion Resistant Wear Plate Manufacturer & Supplier
Stanhard 400 is a low-alloyed quenched & tempered martensitic wear plate with a nominal hardness of 360-430 HBW. It combines abrasion resistance with the formability, weldability and toughness needed for fabricated wear parts. The most formable grade in the family — it is the only Stanhard grade rated for a full 180° bend.
