These conversion charts are provided for guidance only as each scales uses different methods of measuring hardness. The depth of Penetration is inversely proportional to the hardness. Annealed Drawn Non-magnetic. 55 90. The below chart is useful for determining which metals will be impervious to scratching and dinging, as it relates to the Rockwell scale and ductility. 150 - 200 190 - 220 320 415 352. This table shows approximate hardness of steel using Brinell, Rockwell B and C and Vickers scales. INFORMATIONS 22 ... ASTM E 140, Standard Hardness Conversion Tables for Metals, (for information on where to find, see at the end of this publication) is the best known and authoritative such compilation. When the hardness is higher than 20HRC, 1HRC≈10HB, When the hardness is lower than 20HRC, 1HRC≈11.5HB. 45 Permeability. Magnetic Magnetic. The committee responsible for this document is ISO/TC 164, Mechanical testing of metals, Subcommittee SC 3, Hardness testing. This third edition cancels and replaces the second edition (ISO 6508-1:2005), which has been technically revised. 80 - 90B 83 - 95B 80 - 90B 80 - 90B 80 - 90B 90 - 95B 35C 44C 38C. ROCKWELL HARDNESS TESTING 17 6. 45 40. Machinability % of CD1212. Details of the software products used to create this PDF file can be found in the General Info relative to the file; the PDF-creation parameters were optimized for printing. Non-magnetic Magnetic . 150 - 180 160 - 180 150 - 180 150 - 180. HRC / HB approximate conversion tips. The Rockwell scale is a hardness scale based on indentation hardness of a material. HARDNESS- It is defined as the resistance of a metal to plastic deformation against Indentation, scratching, abrasion of cutting. The hardness of a material by this Rockwell hardness test method is measured by the depth of Penetration of the indenter. > Download above metal hardness chart. 60 73. Rockwell hardness test into what is today the most widely used method for acceptance testing and process control of metals and metal products. Non-magnetic Non-magnetic. Both ball or diamond cone types of indenters are used in this test. Metal Hardness Chart. Since its development, the popularity of the Rockwell hardness test has steadily grown. The Rockwell hardness test continues to be applied as a tool for The right hand … Hardness Brinell Rockwell. Non-magnetic to slightly magnetic Magnetic. Every care has been taken to ensure that the file is suitable for use by ISO member bodies. Steel Hardness Conversion Table.
