75Ni8 Steel Strip Hardened and Tempered Bright Polished

Alloy steel strips are made by adding various alloyed elements (such as chromium, nickel, and molybdenum) to carbon steel. This enhances certain properties like strength, toughness, and corrosion resistance. Different grades contain specific alloyed elements to emphasize the main properties which are important for specific applications. For example, 75Ni8 steel, is often used in the manufacture of saw blades and bandknives.
