Q4. Difference between SS316L and SS316
Ans. 
SS316L has lower carbon content than SS316, making it more corrosion resistant and suitable for welding applications.
• SS316L has lower carbon content (0.03% max) compared to SS316 (0.08% max)

• SS316L is more corrosion resistant due to the lower carbon content

• SS316L is commonly used in welding applications where post-weld annealing is not possible

• SS316 is more commonly used in applications where higher strength is required
