Frequently Asked Questions (FAQ)
The percentage concentration of chromium, nickel and molybdenum (3-4% Mo) in SS 317 is greater than in SS 316 (2-3% Mo). This increases the resistance of SS 317 to pitting and overall corrosion by acidic conditions by a great margin.
The "L" stands for low carbon. SS 317L inhibits the formation of carbide throughout the welding process and this makes the same corrosion resistance of the welded joints the same as the rest of the pipe.
Yes, 317L pipes demonstrate high resistance to sulfuric acid as high as 5% concentration to temperatures as high as 49-C, which is superior to the normal 304 and 316 grades.
No, in an annealed form 317L is a non-magnetic austenitic stainless steel. Cold working or welding could however make it slightly magnetic.
Stress-to-rupture and tensile pressure of pressure ratings is determined by size and temperature, however, in general, 317L pipes have higher pressure ratings compared to 316L, and it is safer to use such a pipe with high-pressure chemical lines.
