  • Cast Iron Brinell Hardness, Ductile Iron and Gray Cast

    2020-12-31 · Brinell hardness is a typical hardness specification for cast iron products, especially for ductile iron and gray cast iron. However, in the most international standards, cast iron hardness is not a necessary inspection specification. Only in Chinese standards, we could see the normal Brinell Hardness (HBS) range for common cast iron grades.

  • Brinell Hardness an overview ScienceDirect Topics

    The Brinell hardness test consists of applying a constant load, usually in the range 500–3000 N, for a specified period of time (10–30 s) using a 5 or 10 mm diameter hardened steel or tungsten carbide ball on the flat surface of a work piece. The Brinell hardness number (HB) is then obtained as: (1) HB = P πD [ D − (D2 − d2)1 / 2]

    David Mills, in Pneumatic Conveying Design Guide (Third Edition), 2016. Hardness. Hardness can be defined as the resistance of a material to an applied pressure or force. Brinell hardness. The Brinell hardness number is a number proportional to the load or test force of a hard steel ball to the calculated curved area of the indentation formed. The ball diameter is 1, 2.5, 5, or 10 mm.

  • Brinell (Hardness) SN Cast Iron

    Brinell hardness is sometimes quoted in megapascals, the Brinell hardness number is multiplied by the acceleration due to gravity, 9.81 m/s 2, to convert it to megapascals. The BHN can be converted into theultimate tensile strength (UTS), although the relationship is dependent on the material, and therefore determined empirically.
