Stainless Steel 316 Density

Understanding the density of Stainless Steel 316 is essential for engineers, designers, and manufacturers. This property refers to the mass per unit volume of the material, which helps in determining weight, structural integrity, and cost estimation.

In metric units, the density of SS 316 is approximately 8 g/cm³, meaning that one cubic centimeter of this material weighs 8 grams. In English units, it's around 0.290 lb/in³, indicating that one cubic inch of SS 316 weighs 0.290 pounds. These values are critical when calculating the weight of components made from this alloy.

The density of Stainless Steel 316 plays a significant role in various applications, especially where precise weight calculations are required. Whether you're designing a product or estimating material costs, knowing the density ensures accuracy and efficiency.

X5CrNiMo17-12-2 is commonly used in high-corrosion and high-temperature environments. Check the electrical resistivity of SUS 316 grade for more information.

Due to its molybdenum content, this material offers superior resistance to corrosion and heat, making it ideal for use in demanding conditions. It's often used in marine, chemical processing, and medical industries.

Electrical resistivity measures how well a material resists the flow of electric current. SS 316 has a relatively high resistivity compared to metals like copper and aluminum. This means it's not a good conductor of electricity but is often used in applications where electrical resistance is desired.

Alloy 316 has great creep strength. Learn about the machinability of 316 Stainless Steel.

Creep strength refers to the ability of a material to withstand deformation under constant stress at high temperatures. This makes Alloy 316 suitable for long-term exposure to extreme heat and pressure, such as in industrial and offshore applications.

The machinability of SS 316 is rated at 60%, which means it is somewhat difficult to machine compared to materials with higher machinability ratings. Special tools and slower cutting speeds are usually required, increasing machining time and cost.
