Stainless Steel Sheet Polishing

Penn Stainless can polish nearly any stainless steel plate item to a #4 polish, #6 Polish, #7 polish or a #8 mirror finish. Stainless plates can be polished on one side or two sides.  Stainless steel polished sheet can also be cut to size. More Information Technical Question?

Stainless Steel Sheet Forming

Penn Stainless can form stainless steel sheet into angles, channels and other shapes per customer request. More Information Technical Question? 

Heatreating & Annealing

Some grades of stainless steel sheets can be heatreated to change the mechanical properties. Precipitation Hardening Stainless Steels such as 17-4PH can be heatreated. 410 stainless steel plate can also be heatreated.  In some cases, secondary annealing 300 series stainless steel may be required depending on the application More Information Technical Question?

Positive Material Identification (PMI)

Penn Stainless 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. More Information Technical Question?

Cold Rolled Stainless Steel Sheet Specifications

Sheet can also be ordered to different finishes. A description of the standard finishes available on sheet follows. Penn Stainless Products does not have the capability to polish sheet but will outsource the polishing when required by the customer.

Some of the common surface finishes for stainless steel sheet are described below. By bar the 2B finish is the most common non polished surface finish for cold rolled stainless steel sheet.  Please feel free to submit a technical question or special request.  Click the “more info” link to learn more about these finishes.

Unpolished or Rolled Finishes:

No 1

A rough, dull surface, which results from hot rolling to the specified thickness, followed by annealing and descaling. Technical Question? More Info

No 2D

A dull finish which results from cold rolling followed by annealing and descaling, and may perhaps gets a final light roll pass through unpolished rolls. A 2D finish is used where appearance is of no concern. Technical Question? More Info

No 2B

A bright, cold-rolled finish resulting in the same manner as No.2D finish, except that the annealed and descaled sheet received a final light roll pass through polished rolls. This is the general-purpose cold-rolled finish that can be used as is, or a preliminary step to polishing. Technical Question?
More Info

(BA) Bright Anneal

The bright annealed mill surface is obtained by annealing the material under an atmosphere so that scale is not produced on the surface. Technical Question? More Info
