Strength is a critical factor in metal uses, for example, some applications require stronger aluminum parts, while some products need high steel hardness or yield strength of steel, this may determine the selection of CNC machining material or product design. So whats the catch? B. But with these tables it is concluded that because of different hardness test methods defining a single conversion method is not possible, Thats why these standards formulate tables for conversion process, with test load and hardness ranges.
