Alloy 317L
Introduction :
One of our most popular products is the alloy 317L pipe. The 317L battles any chemicals, like chlorine, that it may come in contact with. This, in mixture with a low carbon content, allows the pipe to battle corrosion and have a longer life. Several industries benefit from using 317L stainless steel. In general, if you need a supple and durable metal, the 317L is right for you. This particularly holds true if you plan on exposing your metal to substances.
The 317L also features the following characteristics:
- Higher strength than other stainless steels
- Good formability and weldability
- More chromium, nickel, and molybdenum compared to the 317L stainless (a higher molybdenum content means more resistance to sulfuric acid)
Some of the industries we service include:
- Flue-gas desulfurization scrubber systems
- Food processing industries
- Power plants
- Paper and pulp plants
- Petrochemical and chemical processing
- Textile equipment
