Nickel Alloy Fasteners Weight Chart
Precision Mass Calculation

Because each of these distinct alloys possesses a unique microstructural composition—incorporating varying percentages of heavy transition metals such as nickel, molybdenum, tungsten, and chromium—their volumetric mass density varies significantly. A Titanium Grade 5 socket head cap screw will exhibit a drastically different mass profile compared to an identical component manufactured from Hastelloy B2.

• The Inconel Family: Inconel 600 (8.47 g/cm³), Inconel 625 (8.44 g/cm³), and Inconel 718 (8.19 g/cm³) are austenitic nickel-chromium-based superalloys engineered for exceptional performance in extreme high-temperature environments.
• The Hastelloy Family: Distinguished by heavy alloying with molybdenum and tungsten. Hastelloy C276 (8.89 g/cm³) and Hastelloy B2 (9.22 g/cm³) are exceptionally proficient at surviving severe chemical environments.
• The Monel Family: Monel 400 (8.80 g/cm³) and Monel K500 (8.44 g/cm³) are robust nickel-copper solid-solution alloys that excel in marine and hydrofluoric environments.
• Duplex & Titanium: Super Duplex 2507 maintains a density of 7.80 g/cm³, while Titanium Grade 5 offers an exceptionally low density of 4.43 g/cm³ combined with extraordinary tensile strength.

Determining the precise weight of a complex machined component requires deconstructing the geometry into basic volumetric shapes, calculating the volume, and multiplying by specific density. The generalized fundamental formula for calculating mass is:

For an unheaded continuous shank (like stud bolts), the continuous shank volume is calculated using the standard Euclidean formula for a cylinder, where d is outer diameter and L is length:

For Hexagonal Heads (Width across flats F and Head Height H), the total solid volume of the hex head before any chamfering is:

Conversion Multiplier Framework: Extrapolating a superalloy weight from a standard steel base weight chart is done by establishing a relative density multiplier (M_d):
