Stainless Steel 316 Density

Here, the density values represent the mass per unit volume of Stainless Steel 316. The metric value of 8 g/cc indicates that one cubic centimeter of SS 316 weighs 8 grams, whereas the English unit of 0.290 lb/in³ means that one cubic inch of SS 316 weighs 0.290 pounds.

These values are critical when calculating the weight of stainless steel components.

Stainless Steel 316 Density

Properties Metric English
Density 8 g/cc 0.290 lb/in³

AISI 316 is an austenitic stainless steel with added molybdenum, enhancing its corrosion resistance properties.

The addition of molybdenum improves its resistance to general corrosion and pitting, making it ideal for high-temperature applications where creep strength and tensile strength are required.

WNR 1.4401 is resistant to rusting and corrosion, Refer INOX 316 material Thermal Conductivity

WNR 1.4401 exhibits excellent resistance to rust and corrosion, thanks to its molybdenum content. This makes it suitable for use in chemical processing, marine, and offshore environments, protecting it from pitting and crevice corrosion. It is commonly used in medical appliances, food processing, and other industries requiring hygienic standards.

Alloy 316 Magnetic Permeability

Magnetic Permeability 1.02 Max @ 200 H (H/m annealed)

X5CrNiMo17-12-2 is widely used in high-corrosion and high-temperature applications, View Electrical Resistivity of SUS 316 Grade

Its molybdenum content provides superior resistance to rust, chemicals, and extreme heat conditions, making it ideal for harsh environments. This material is commonly used in marine, chemical processing plants, and medical applications.

As shown in the table below, the electrical resistivity of SUS 316 grade demonstrates its ability to resist electrical current. Compared to copper and aluminum, it has a higher resistivity, meaning it is not as good a conductor of electricity. Copper, with its lower resistivity, is the preferred material for electrical applications.

Alloy 316 Grade Has Great Creep Strength, Check Machinability of 316 Stainless Steel

With excellent creep strength, Alloy 316 can withstand extreme heat and continuous pressure without damage. This makes it suitable for applications like industrial equipment, medical instruments, and offshore uses where exposure to extreme conditions is necessary.

The machinability of SS 316 is 60%, indicating that it is somewhat harder to machine compared to materials with a machinability rating of 100%. It does not possess the best machinability qualities compared to free-machining alloys.

Machining SS 316 requires specialized cutting tools and slower speeds, increasing costs and reducing efficiency. Its hardness and tendency to work-harden lead to shorter tool life and longer machining times, affecting productivity.
