What is Stainless Steel 316?

Stainless Steel 316 is an alloy made up of iron, chromium, nickel, and molybdenum, which gives it enhanced resistance to corrosion, particularly in chloride environments. The addition of molybdenum (approximately 2-3%) distinguishes Stainless Steel 316 from other stainless steel grades, such as 304, by providing superior resistance to pitting and crevice corrosion. This makes it an excellent choice for applications in harsh environments, including saltwater exposure.

The primary composition of Stainless Steel 316 includes:

• Chromium (16-18%): Enhances corrosion resistance and hardness.
• Nickel (10-14%): Improves strength and corrosion resistance.
• Molybdenum (2-3%): Provides resistance to pitting and crevice corrosion.
• Iron (Balance): The primary base metal in the alloy.
