A182 F316 /316L is a commonly used grade in American Standard represents stainless steel fittings.

 

Stainless steel is created for high temperature/perssure and corrosive environments.It has has superior performance especially in the corrosive environment,design life over 50 years.Annealed condition makes stainless steel better corrosion resistance,so annealed stainless steels are commonly used in some chemical industries.

316 VS 304

316 has more salt and corrosion resistance than 304.You can distinguish 316 and 304 by the magnet test.304 will stick with magnets, while 316 and cold worked 304 will not.

 

Stainless steel and Galvanized

Steel is galvanized to prevent corrosion,while stainless steel is inherently resistant to corrosion.Galvanized is more ductile and easier to machine; stainless steel is stronger and more resistant to corrosion.In addition,Galvanized design life always be 20 years,but there is 50 years for stainless.Therefore,stainless is more expensive by its superior properties.

 

Stainless steel pipe fittings including Tee,Cross, Elbow, Reducer, Coupling, Nipple, Plug & Cap,Union.They can be connected with pipes by welding, socket and thread.
