Although there is no accurate conversion tables and equations, but dandong foundry recommend the following formulas and comparison tables according to the experience and standards. Also hardness ranges for heat treated steel Pure copper FSW joint tensile strength is slightly lower than that of BM; however, it has been shown to have higher tensile strength when compared to electron beam welded (EBW) joints [5].Failure occurs near the HAZ, which also shows the least hardness [15]. The many hardness tests listed here measure hardness under different experimental conditions (e.g. Rockwell Hardness (HRC and HRB) and Brinell Hardness (HB or BHN) are most commonly used for steel and iron castings. Take a look below and see the various metals like Platinum, Palladium, Titanium, Tungsten, Brass, Steel, Copper, Gold and Silver to see how they stack up to each other in terms of hardness.
