Frequently Asked Questions – Stainless Steel 316 Pipe Fittings
What are Stainless Steel 316 Pipe Fittings?
Stainless Steel 316 Pipe Fittings are piping components manufactured from Grade 316 austenitic stainless steel. They are used to connect pipes, change flow direction, create branches, reduce pipe diameter and terminate piping systems.
What is ASTM A403 WP316?
ASTM A403 WP316 is a material specification for wrought austenitic stainless steel pipe fittings manufactured from Type 316 stainless steel for pressure piping applications.
Why is Stainless Steel 316 used for pipe fittings?
SS 316 contains molybdenum, which improves its resistance to pitting and crevice corrosion. It is therefore commonly selected for applications involving chlorides, marine environments, chemicals and demanding industrial conditions.
What types of Stainless Steel 316 Pipe Fittings are available?
Common configurations include 45-degree elbows, 90-degree elbows, tees, reducing tees, concentric reducers, eccentric reducers, caps, stub ends and crosses.
What is the difference between SS 316 and SS 304 pipe fittings?
SS 316 contains molybdenum and generally offers better resistance to pitting and crevice corrosion than SS 304. SS 304 is often selected for general-purpose applications where the additional corrosion resistance of 316 is not required.
SS 316L has a lower carbon content than SS 316. It is commonly selected for welded applications where reducing the risk of sensitization is important.
Does Mcneil Instruments supply SS 316 Pipe Fittings in the USA?
