Inconel Weight Calculator

Inconel 625 has a density of 8.44 g/cm³ (0.305 lb/in³ or 525 lb/ft³). This makes it significantly denser than stainless steel due to its high nickel and chromium content, which contribute to its superior corrosion and heat resistance.

Inconel is approximately 6-8% heavier than 316 stainless steel. While 316 stainless has a density around 8.0 g/cm³, most Inconel grades range from 8.19 to 8.47 g/cm³, with the difference mainly due to higher nickel content.

Inconel 718 is the lightest common grade at 8.19 g/cm³ (0.296 lb/in³). Despite being slightly lighter, it offers excellent strength at elevated temperatures and is widely used in aerospace applications like turbine blades and rocket components.

The density remains essentially the same between hot-rolled and cold-rolled Inconel. However, cold-rolled material may have tighter thickness tolerances, which can affect the calculated weight slightly. The material processing affects mechanical properties more than density.

For round bar, use πr²L × density. For tube, calculate the wall volume: π(R² - r²)L × density, where R is outer radius and r is inner radius. Convert all dimensions to consistent units before calculating.
