Q3. What is the difference between SS316 and SS304
Ans. 
SS316 has higher corrosion resistance and strength compared to SS304.
• SS316 contains molybdenum which enhances its corrosion resistance, while SS304 does not.

• SS316 is more suitable for use in harsh environments like marine applications, while SS304 is more commonly used in indoor settings.

• SS316 has higher tensile strength and creep strength than SS304.

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
