Frequently asked questions
How do you calculate the weight of stainless steel square bar?
Multiply the cross-section area in square inches by the length in inches and by the density, 0.289 lb per cubic inch for stainless steel (304). For this shape the area is: area = side squared. A foot of stock is 12 inches, so weight per foot is area x 12 x 0.289.
How does stainless steel compare with steel by weight?
Stainless steel is 2% heavier than carbon steel for the same size: 0.289 lb per cubic inch against 0.2836. The same bar or plate in stainless steel weighs 1.02 times the steel figure.
