Description
Alloy 316L
It is an austenitic stainless steel containing chromium, nickel, and molybdenum that was developed to provide improved corrosion resistance to Alloy 304/304L in moderately corrosive environments. It is designated by the UNS S31603 designation. It is frequently used in the processing of streams that contain chlorides or halides. When molybdenum is added to a solution, it improves the overall corrosion and chloride pitting resistance. Additionally, it has higher creep, stress-to-rupture, and tensile strength when exposed to higher temperatures. It is common for 316L to be dual certified as both 316 and 316L, which is common practise. When combined with the nitrogen addition, the low carbon chemistry of 316L results in mechanical properties that are comparable to those of 316. Alloy 316/316L is resistant to corrosion caused by the atmosphere, as well as moderately oxidising and reducing environments. It also has excellent corrosion resistance in polluted marine environments.
While in this as-welded condition, the alloy exhibits exceptional resistance to intergranular corrosion. At cryogenic temperatures, the alloy 316/316L demonstrates exceptional strength and toughness. Stainless steel alloy 316/316L is nonmagnetic in its annealed state, but it can become slightly magnetic as a result of cold working or welding. It is simple to weld and process using standard shop fabrication practises in a fabrication shop.
