Stainless steel 316 is an incredibly versatile material widely used in various industries due to its excellent strength, corrosion resistance, and durability. But have you ever wondered about ss density? This guide delves into everything you need to know about stainless steel 316 density, including its definition, applications, and why it matters.

What is Stainless Steel 316?

Stainless steel 316, also known as UNS S31600, belongs to the austenitic family of stainless steels. It is characterized by its high chromium content (16-18%) and molybdenum addition (2-3%). This composition grants it superior corrosion resistance, particularly in chloride-rich environments, compared to other grades like 304. Additionally, 316 stainless steel excellent formability, weldability, and mechanical properties make it a versatile material used in various industries, including:

  • Food processing: Equipment and utensils
  • Marine: Boat fittings and hardware
  • Chemical processing: Tanks and pipelines
  • Architectural: Building facades and decorative elements
  • Medical: Surgical instruments and implants

What is the Density of Stainless Steel 316 in kg/m3, g/cm3, lb/in3, lb/ft3

The density of stainless steel 316 is 7980 kg/m3 or 8.0 g/cm³ (0.289 lb/in³00). This density is slightly higher than other common stainless steel 304 is 7930 kg/m³ or 7.93 g/cm³ (0.286 lb/in³) due to the addition of molybdenum, which enhances its corrosion resistance.SS 304 is less dense than stainless steel 316, but somewhat denser than stainless steel 430 at 7750 g/m3.
