Calculator

To calculate the weight of any metal: (1) Determine the piece volume based on its shape. (2) Find the density of the specific alloy (304 stainless = 0.289 lb/in3; Monel 400 = 0.319 lb/in3; titanium Grade 2 = 0.163 lb/in3). (3) Multiply Volume x Density = Weight. The Stainless Shapes calculator supports stainless, nickel alloys, and titanium across multiple shape types.

One foot of stainless steel weight depends on the shape. For a 1" diameter round bar: approximately 2.67 lbs/ft. For a 1" x 1" square bar: approximately 3.40 lbs/ft. For a 1" x 1/4" flat bar: approximately 0.850 lbs/ft. Use the Stainless Shapes metal weight calculator for exact values in any size and alloy.

The specific weight formula for steel is: W = L x A x rho, where L is length, A is cross-sectional area, and rho is the material density (approximately 0.284-0.291 lb/in3 for stainless grades). For plate: W = Length x Width x Thickness x 0.2836 lbs/in3.

To calculate steel weight in feet: find the cross-sectional area in square inches, multiply by the length in inches (feet x 12), then multiply by the material density in lb/in3. The Stainless Shapes calculator accepts inputs in both inches and feet and returns weight in pounds.

Stainless steel weighs slightly more than carbon steel: approximately 0.289 lb/in3 for stainless versus 0.284 lb/in3 for carbon steel -- a difference of roughly 2%. For practical estimates they are treated as equivalent, but the Stainless Shapes calculator uses the precise density for each alloy.

For a project estimate: list all pieces by shape and alloy, calculate weight for each using volume x density, sum all pieces, then add a 10-15% scrap factor for machined parts. The Stainless Shapes calculator allows rapid estimation of individual pieces before requesting a quote.

The Stainless Shapes calculator supports stainless steel (304, 316, 17-4 PH, and others), nickel alloys (Monel, Inconel 625/718, Incoloy 800/825, Nickel 200/400/600), and titanium alloys. It covers round bar, square bar, flat bar, hex bar, plate, sheet, pipe, and tube product forms.

Knowing accurate metal weight is critical for calculating shipping freight costs, verifying structural load requirements, budgeting material purchases, and ensuring lifting equipment is rated for the load. For high-value alloys like Inconel or titanium, accurate estimates have significant impact on project cost.

Yes, the Stainless Shapes calculator includes pipe and tube forms. Enter the outer diameter, wall thickness, and length to get an accurate weight estimate -- particularly useful for planning bulk pipe or tube orders where freight cost is a significant portion of the delivered price.
