Alloy 316 / alloy 316L is the most used austenitic stainless steel in the chemical process industry, including steel tubing. The higher nickel and molybdenum content in this grade allows it to demonstrate better overall corrosion resistant properties than alloy 304/304L, especially with regard to pitting and crevice corrosion in chloride environments. The steel also offer higher creep, stress rupture and tensile strength in elevated temperature. Alloy 316L is an extra-lower carbon version of alloy 316 that eliminates harmful carbide precipitation due to welding. Generally all Merinox tubing is dual- certified to meet both type alloy 316 and type alloy 316L.

Characteristics alloy 316/316L:

  • Higher creep resistance
  • Excellent formability and weld ability
  • Rapture and tensile strength at high temperatures
  • Corrosion and pitting resistance
  • Exceptional resistance in acid and hand water areas

Market applications:

  • Chemical & pharmaceutical
  • Refining oil & gas
  • Instrument construction and engineering products
  • Shipbuilding and hydraulics construction and engineering products
  • Paper industry digesters, evaporators & handling equipment
  • Surgical and medical tools
