1Test method uses 1/2 sized un-notched charpy bar.
Low alloy steel, carbon, nickel, molybdenum. A multipurpose, economical material that offers various strength, hardness and wear resistance properties depending on whether it is heat treated and which heat treat process is used. Magnetic. Can be plated or coated for corrosion resistance. Used by a very wide range of industries including automotive, consumer products, firearms, power hand tools, structural and applications where good strength, hardness and wear resistance are required.
An austemper heat treat imparts some spring characteristics to the material, while increasing hardness, wear resistance and impact strength over that of an as-sintered part.
