Material selection for ice salt pipelines

Previously, the ice salt pipelines used within the factory were made of 20# seamless carbon steel pipes. Now the management has said that corrosion-resistant steel should be used, but they didn’t specify any particular grade. I don’t know what kind of steel to use, nor do I dare to ask. I’m seeking advice from those who are more experienced in this area. Could you point me in the right direction?

316L is the best choice; 304 is the minimum acceptable standard, while grade 20 steel is not suitable

Austenitic steel isn’t as good as 20# steel yet

For saltwater corrosion protection, please choose the polyaniline nano-corrosion inhibitor coating 15201407626
