WebThe Brinell Hardness Test consists of indenting the test material with a 10mm diameter hardened steel or tungsten ball subjected to a load of 3000 kg. For softer materials, there are alternate scales using a 1500 kg or 500 kg load to avoid excessive indentation. The full load is applied for 10 to 15 seconds for iron or steel and at least 30 ... WebJun 25, 2005 · 23 Jun 05 16:38. We were testing 17-4PH condition H900, .0831 in diameter, for Rockwell testing. We found from our labs that it had a low Rockwell, around 35-36. We decided to get them tested via tensile strength and use the results to get the rockwell hardness number. Again these ranged from 34-36 where as it should have ranged from 40 … how to roll paper into fire logs
