body,td,th { 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. Steel Hardness Conversion Table. The test is to determine the hardness of a metal by pressing a steel ball of a standard size into the metal using a standard force. Brinell hardness number definition is - a number expressing Brinell hardness and denoting the load applied in testing in kilograms divided by the spherical area of indentation produced in the specimen in square millimeters —called also Brinell number. We don't save this data. BHN or Brinell Number is the numerical value assigned to the hardness of metals and alloys. The units of the BHN are kgf/mm 2. Although this standard specifies the unit of force in the International System of Units (SI) as the Newton (N), because of the historical precedent and continued common usage of kgf units, force values in kgf units are provided for information and much of … The Brinell conversion chart is then used to convert the average diameter of the indentation made to the corresponding Brinell hardness value. BHN - Brinell Hardness Number, which is the same meaning as HB. Hardness Conversion Table – Brinell, Rockwell,Vickers – Various steels . BRINELL HARDNESS: Drilled Diameter With Suggested Feed Rate Below: 1/16″ 1/8″ 1/4″ 1/2″ 3/4″ 1″ 1-1/2″ 2″ Aluminum: 99-101.001.003.007.012.016.020.025.030: Aluminum Bronze: 170-187.001.003.004.008.010.012.015.020: Balkelite –.002.005.006.008.010.012.015.015: Brass: 192-202.001.003.004.008.012.018.020.022: … The Brinell and Rockwell conversion table provides different scales and its tensile strength. Brinell Hardness Number; Soft brass: 60: Mild steel: 130: Annealed chissel steel: 235: White cast iron: 415: Nitrided surface: 750 HBW indicates that the indenter is a hard alloy, which is used to measure materials with a Brinell hardness value below 650. It is one of several definitions of hardness … The Brinell hardness test is commonly used to determine the hardness of materials like metals and alloys. Approximate Hardness Conversion Numbers for Wrought Aluminum Products: Brinell Hardness No. Engineering Forum Test forces range from 500 to 3000 kgf. Hardness Testing Hardness testing can best be described as a measurement of “resistance to penetration” to a defined load. Brinell hardness of martensitic stainless steel – Grade 440C is approximately 270 MPa. The Brinell Hardness Number may be calculated from the diameter of that indentation. (archived November 11, 2011) Rockwell to Brinell conversion chart (Brinell, Rockwell A,B,C) Struers hardness conversion table (Vickers, Brinell, Rockwell B,C,D) This page was last edited on 27 September 2020, at 21:09 (UTC). The Brinell hardness number (HB) is the load divided by the surface area of the indentation. Brinell Hardness test works according to the ASTM E10 standard.
