Your Alloy 316L Stainless Steel Distributor
The chromium-nickel-molybdenum composition of alloy 316/316L stainless steel allows it to withstand extreme conditions. In almost any environment, alloy 316L pipe, valves, and bars resist chemical corrosion and chemical pitting. If you need a metal alloy with these features for equipment parts or welding applications, James Duva Inc. can help you make the right alloy choice for your project.
Design Features of Alloy 316/316L
Each alloy 316L pipe, pipe fitting, bar, and valve we make is resistant to corrosion. This alloy remains strong even after repeated exposure to corrosive chemicals.
Other special characteristics of alloy 316L include the following:
- Resistant to carbide precipitation
- Resistant to pitting from chloride-containing solutions
- Easy to weld (at a max temperature of 1650 degrees Fahrenheit)
- Non-magnetic and non-hardenable
You can heat and cool alloy 316/316L to extreme temperatures for welding or other purposes. This heating and cooling will have no effect on its chemical resistance. An alloy 316L pipe, pipe fitting, bar, or other part is optimal for welding due to its lower carbon content.
Applications of Alloy 316/316L
The features of alloy 316L make it an ideal metal for multiple environments. If you need a metal that resists damage from chemicals or at high and low temperatures, choose alloy 316L for the best results. A few specific industries that use alloy 316L are:
- Nuclear plants
- Pharmaceutical processing
- Textile industries
- Chemical processing plants
- Rubber factories
- Plastic factories
- Petroleum refining

- Type 316 is more resistant to atmospheric and other mild environments than Type 304. It is resistant to dilute solutions (i.e. 1-5%) of sulfuric acid up to 120 ̊ F. However, in certain oxidizing acids, Type 316 is less resistant than Type 304.
- 316 is susceptible to carbide precipitation when exposed in the temperature range of 800 ̊ – 1500 ̊ F and therefore is susceptible to intergranular corrosion in the as-welded condition. Annealing after welding will restore corrosion resistance.
- Type 316L has the same composition as Type 316 except the carbon content is held below 0.03%. Not unexpectedly, its general corrosion resistance and other properties closely correspond to those of Type 316. However, it does provide immunity to intergranular attack in the as-welded condition or with short periods of exposure to the temperature range of 800 ̊ – 1500 ̊ F. The use of 316L is recommended when exposure in the carbide precipitation range is unavoidable and when annealing after welding is not practical. However, prolonged exposure in this range may embrittle the material and make it susceptible to intergranular attack.
- The maximum temperature for scaling resistance in continuous service is about 1650 ̊ F, and 1500 ̊ F for intermittent service.
- May be susceptible to chloride stress corrosion cracking.
- Non-hardenable; non-magnetic in the annealed condition, and slightly magnetic when cold worked.
- Improved corrosion resistance to chlorides.
