ASTM A269 TP 316L Stainless Steel Seamless Tubes Value Added Service
Polishing |
Victor Steel can 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. |
Beveling |
Victor Steel can bevel stainless steel pipe to prepare for welding or other processes. |
Honing/Turning |
Victor Steel can 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 and tube can be heatreated to change the mechanical properties. Precipitation Hardening Stainless Steels such as 17-4PH can be heatreated. In some cases, secondary annealing 300 series stainless steel may be required depending on the application |
Positive Material Identification (PMI) |
Victor Steel can perform 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 pipe and tueb may be required. We can assist you with this requirement. |
