To convert Brinell Hardness to tensile strength. : Divide the Brinell Hardness number by two to get the approximate tensile strength in thousands of pounds pet square inch. EXAMPLE.. Assume Brinell Hardness of 248 248+2 = 124,000 post. (approx. tensile strength) Conversely, drop the last three figures of the tensile strength and multiplying the two to get the approximate Brinell Hardness EXAMPLE: Assume tensile strength of 122,000 post. 122X2=244 (approximate Brindle Hardness)
To estimate the weight of a round steel bar: Multiply the diameter by 4, square the product, and divide by 6. The result is the approximate weight in pounds per foot of length.
