Stainless Steel 316 is a molybdenum-bearing austenitic stainless steel known for its superior resistance to corrosion, particularly in chloride-rich and marine environments. Stainless Steel 316 pipes and tubes are widely used in chemical, marine, pharmaceutical, and food processing industries.

What is Stainless Steel 316?

Stainless Steel 316 is an austenitic chromium-nickel stainless steel alloy containing molybdenum (2–3%) which enhances its resistance to pitting and crevice corrosion compared to SS 304. Stainless Steel 316 pipes and tubes are highly versatile and ideal for applications exposed to harsh chemical or marine environments.

Key features of Stainless Steel 316 pipes and tubes include:

  • Exceptional corrosion resistance in harsh and chloride environments
  • Excellent mechanical strength
  • High-temperature resistance
  • Good weldability and formability
  • Non-magnetic in annealed condition
  • Hygienic and easy-to-clean surface

These properties make Stainless Steel 316 the preferred choice for industries where durability and corrosion resistance are critical.


Chemical Composition of Stainless Steel 316 (%)

  • Chromium (Cr): 16.0 – 18.0%
  • Nickel (Ni): 10.0 – 14.0%
  • Molybdenum (Mo): 2.0 – 3.0%
  • Carbon (C): ≤ 0.08%
  • Manganese (Mn): ≤ 2.0%
  • Silicon (Si): ≤ 1.0%
  • Phosphorus (P): ≤ 0.045%
  • Sulfur (S): ≤ 0.03%
  • Iron (Fe): Balance

Role of Alloying Elements

  • Chromium: Provides corrosion and oxidation resistance.
  • Nickel: Improves ductility, toughness, and resistance to cracking.
  • Molybdenum: Enhances resistance to pitting and crevice corrosion in chloride environments.
  • Low Carbon Content: Prevents carbide precipitation during welding.

The combination of these elements ensures that Stainless Steel 316 maintains its integrity in aggressive chemical and marine conditions.
