What is HRB in hardness? – AnswersToAll

Mar 21, 2021 · Is 45 HRC harder than 60 HRC? Softer metals allow for deeper penetration than harder metals, so the B – A value will always be higher on soft metal test subjects than hard metals. The Rockwell hardness scale number appears inverse to the depth differential calculation. For instance, a soft Rockwell value is 45, whereas a hard value is 60.sp.info HARDNESS CONVERSION TABLE - Ravne Systems445 45 58,4 67 59,3 680 646 432 43,9 57 66 58,0 672 637 420 42,8 55,9 65 56,7 663 628 412 42 54,9 - 55,9 658 622 402 41 53,7 - 54,9 650 615 392 40 52,6 - 53,8 642 608 382 39 51,5 - 52,7 634 601 372 38 50,4 - 51,6 628 594 ...
