METHODS TO ESTIMATE APPROXIMATE WEIGHT OF TOOL STEEL BARS

ROUNDS

Multiply diameter of bar by 4. Square the result and divide by 6.

For example:

Size 3” round

3 X 4 = 12

12 X 12 = 144

144 ÷ 6 = 24 lbs. per foot

Square the section and add a zero. This will give the weight per yard. Divide by 3 to get the weight per foot. For example:

Size 4” square

4 X 4 = 16

Add a zero = 160 lbs. per yard

160 ÷ 3 = 53.33 lbs. per foot

Multiply the width by the thickness. Add a zero and divide by 3.

For example:

Size 4” X 1”

4 X 1 = 4

Add a zero = 40

40 ÷ 3 = 13.33 lbs. per foot

NOTE: For Molybdenum High Speed grades, multiply tool steel weights by 1.03. For Tungsten High Speed grades, multiply steel weights by 1.11
