Advantages:
Corrosion Resistance: AISI 316L stainless steel displays as much as possible corrosion resistance in different environments such as acidic and high-temperature ones.
High Strength: It has a good tensile strength and durability, making it a great choice to apply in structural spaces where strength is essential.
Formability: AISI 316L is a material that is easier to form and manufacture into different shapes enabling for diverse construction.
Weldability: Its low carbon content not only improves weldability, but also facilitates assembly and welding processes. Consequently, working with it would be less complicated.
Temperature Resistance: AISI 316L offers amazing performance at high temperatures because it is stable and reliable under extreme conditions.
Disadvantages:
Magnetic Properties: AISI 316 stainless steel is commonly magnetically by the mild magnetic effect what can lead to the rejection by some applications where magnetism is not required.
Work Hardening: It works prone to over hardening under forming operations and thus resulting in the loss of ductility that could be regained by annealing or heat treatment.
Cost: For instance, other for grades than AISI 316L stainless steel can cost relatively a lot, so the affordability is affected in some applications.
Surface Finish: Getting any given smooth surface finish can be difficult especially when the work-hardening property of this material is relocated at machining stage.
Sensitivity to Chloride: AISI 316L is at risk of getting localized corrosion in chloride rich, surroundings, so it is essential to take a cautious approach when choosing this alloy for marine or coastal structures.
