SPECIFICATION
APPLICATIONS
304 / 304L pipe is used for handrails, posts and poles in marine and outdoor applications.
316 / 316L is used for Structural applications include handrails, poles and support pipe for salt water and corrosive environments. It is not used as often as welded pipe due to its reduced weldability compared to 304 stainless unless its superior corrosion resistance outweighs it decreased weldability.

Stainless Steel Value Add | |
Stainless Steel Pipe Polishing | polish nearly any stainless steel pipe item to a #4 polish, #6 Polish, #7 polish or a #8 mirror finish. Stainless steel polished pipes can also be cut to size. |
Stainless Steel Pipe Beveling | bevel the edges of stainless steel plate to prepare for welding or other processes. |
Stainless Steel Pipe Honing & Turning | hone pipe and tube, using a precision abrasion process in order to obtain a desired finish or close dimensional tolerance. |
Heatreating & Annealing | some grades of stainless steel pipe can be heatreated to change the mechanical properties. |
Positive Material Identification (PMI) | pMI testing in house for most stainless steel grades, or we can work with independent labs to complete PMI in order to meet customer specifications. |
UT Testing | in some cases, UT testing of the stainless steel plates may be required. We can assist you with this requirement. |
