316 Stainless Steel Tubing are molybdenum-bearing austenitic stainless steel, which are more resistant to general corrosion and pitting corrosion, crevice corrosion than the conventional chromium-nickel austenitic stainless steel such as 304. 316L Stainless Steel also offer higher creep, stress-to-rupture, and tensile strength at elevated temperature. The recommended temperature range includes -425°F to 1,200°F (-255°C to 605°C). In addition to excellent corrosion resistance and strength properties, the Alloys 316 and 316L Cr-Ni-Mo alloys also provide excellent fabricability and formability which are typical of the austenitic stainless steel.
316L Stainless Steel Tubing is improved version of 304 Stainless Steel, with the addition of molybdenum and higher nickel content. The resultant Chemical composition of 316 gives the stainless steel much increased corrosion resistance in aggressive environment. Molybdenum make the steel more resistant to pitting and crevice corrosion in chloride-contaminated media, sea water and acetic acid vapour. The lower rate of general corrosion in mildly corrosive environment give the steel good atmospheric corrosion resistance in polluted marine atmosphere, and because of low carbon percentage, can minimizing Intergranular corrosion attact.
316 316L Stainless Steel offers higher strength and better creep resistance at higher temperature than 304. 316L Stainless Steel also possesses excellent mechanical properties and corrosion properties at sub-zero temperatures. When there is a danger of corrosion in the heat affected zones of weldments, the low-carbon variety 316L should be used. 316Ti, the titanium-stabilised version, is used for its resistance to sensitization during prolonged exposure in the 550 °C-800 °C temperature range.
316 316L (2% to 3% Mo) is the most widely used molybdenum-containing stainless steel. It is designated as a tank, pipe and heat exchanger material for food processing and pharmaceutical production. Increased molybdenum content enhances resistance to chloride in the air, so Type 316 can be used as a material of choice for offshore and coastal buildings. 316L is used to cover the Canary Wharf building in London and the tallest building in the world – the outer layer of the Petronas Tower in Kuala Lumpur, Malaysia.
What does the L mean?
L-grades have 0.035% carbon maximum. L-grades are resistant to sensitization in short-term exposures or heat treatments. L-grade often have slightly lower (typically 5,000 psi less) minimum strengths than standard stainless steel.
