What is 317ss?
Grade 317 stainless steel is a modified version of 316 stainless steel. It has high strength and corrosion resistance.
What is the composition of 316 stainless steel?
A popular grade of stainless steel is stainless steel 316. Stainless steel 316 is generally composed of 16 – 18% chromium, 10 – 14% nickel, 2 – 3% molybdenum, and about 0.08% carbon. The added molybdenum makes this grade more corrosion resistant than the other types.
Which is better SS316 or ss316l?
316L is the superior choice for high corrosion and high temperature applications. Since 316L contains less carbon than 316, it has better intergranular corrosion resistance, meaning its welds won’t decay, unlike with 316 stainless steel.
What does the L mean in 316L?
low content of carbon
Type 316 stainless steel is manufactured in another grade due to its widespread potential and it is differentiated by using the letter ‘L’ in its designation. The L denotes the low content of carbon in the steel. 316L is best known among fabricators for being resistant to cracks after the weld process is completed.
Can we use 316L instead of 316?
316L stainless steel is almost identical to 316. The only difference is the carbon content. 316L’s lower carbon content imparts even better corrosion resistance than 316. 316L does not require post-weld annealing.
What is the composition of 316L stainless steel?
Chemical Compositionsa)
| Element | % Present |

| Nickel (Ni) | 10.00 – 13.00 |
| Nitrogen (N) | 0.10 |
| Molybdenum (Mo) | 2.00 – 2.50 |
What is difference between 316 & 316L?
What are the uses of ss317 and ss317l?
Both SS317 and SS317L are widely used in pulp and paper making industry, chemical processing, petrochemical piping and textile industry. 1. UNS Designation & International Equivalent
What is the chemical composition of 317l?

What is the difference between 317l and 316L stainless steel?
The low carbon content of 317L Stainless Steel provides immunity to intergranular corrosion in applications where heavy cross sections cannot be annealed after welding or where low temperature stress relieving treatments are desired. A molybdenum bearing austenitic chromium nickel steel with an alloy content somewhat higher than the 316 grades.
