# Stainless Steel Density Chart: Comprehensive Guide

The most challenging aspect of budgeting for mechanical machining is accurately calculating the cost of stainless steel materials. It is often difficult to arrive at an exact figure, primarily due to the variable density of stainless steel. This variability is because stainless steel is an alloy with diverse components and concentrations, which results in no definitive density.

However, if the ratios of its different components are known, an accurate calculation can be achieved.

The densities of chrome stainless steel, chrome-nickel stainless steel, and chrome-manganese-nitrogen stainless steel all differ due to their varying compositions. Even within the same material, the density can vary based on the different components.

According to national standards and daily accumulations, the approximate densities (g/cm³) of various stainless steels are:

These are some of the most commonly used stainless steel densities. The data may not be entirely accurate and is only provided as a reference.

If you are only making a rough calculation, you can use the general steel density of 7.85g/cm³ for your calculations. The deviation won’t be too large (however, for 316, the material price is too high, so a rough estimate will have a large discrepancy).
For standard materials, we can use relative theoretical data to calculate the weight. The formula is:

Weight (kg) = Thickness (mm) * Width (m) * Length (m) * Density value (g/cm³)

These are some of the most commonly used stainless steel density tables, provided only as a reference. If you are just making an estimate, you can calculate using the general steel density of 7850kg/cm³.
