To calculate the Rockwell Hardness from Brinell Hardness:
\[ R = 130 - (30 \times \sqrt{B}) \]
Where:
A Brinell to Rockwell conversion is a method used to convert the hardness value of a material from the Brinell hardness scale to the Rockwell hardness scale. Both scales are used to measure the hardness of materials, but they use different testing methods and are typically used for different types of materials. The conversion is often necessary because certain industries or applications may prefer or require one scale over the other.
Let's assume the following value:
Using the formula:
\[ R = 130 - (30 \times \sqrt{100}) = 130 - 300 = -170 \]
The Rockwell Hardness is -170.
Let's assume the following value:
Using the formula:
\[ R = 130 - (30 \times \sqrt{200}) = 130 - 424.26 = -294.26 \]
The Rockwell Hardness is -294.26.
