Stainless Steel 316 Density

Stainless Steel 316 Density

The density of Stainless Steel 316 is a critical property that indicates the mass per unit volume of the material. In metric units, it measures 8 g/cm³, meaning one cubic centimeter of SS 316 weighs 8 grams. In English units, the density is 0.290 lb/in³, which means one cubic inch of the material weighs 0.290 pounds.

These values are essential for calculating the weight of stainless steel components, especially in engineering and manufacturing contexts where accurate measurements are vital for design and cost estimation.

Pressure Vessel

A pressure vessel is a vessel that can withstand high pressures and is commonly used for storing, transporting, and processing various gases, liquids, and gaseous liquid mixtures. The pressure vessel is mainly composed of vessel body, flange, seal, support and accessories. Common pressure vessels are gas cylinder, gas storage tank, distillation tower, reactor and so on.


The design and manufacture of pressure vessels must comply with relevant national standards and specifications, and pass strict inspection and testing to ensure their safety and reliability. During use, you must comply with the operation regulations and safety precautions, and periodically check and maintain the device to ensure its normal operation and safe use.
