    Stainless Steel Plate Processing 

    Customers can select a number of processing options to produce stainless steel plates to their exact specifications, reducing materiel costs, production time, scrap and internal handling. All stainless steel grades of plate can be cut. We regularly process stainless steel shapes, stainless steel rings, and stainless steel discs. Dynamic waterjet cutting and laser cutting offer ultra precise tolerances for processed stainless steel plate.

    Plasma Cutting Tables
    Stainless steel plate can be plasma cut from 3/16″ thick thru 6.25″ thick. Stainless steel plates thru 120″ wide and in excess of 40′ long can be plasma cut.
    Dynamic Waterjet Tables
    Stainless steel plate can be waterjet cut from light gauge sheet metal thru 8″ thick stainless steel plates. Stainless plates up to 120″ wide and up to 288″ long can be cut.
    Kasto Plate Saws
    Stainless steel plate or bar from 1/2″ thick thru 22″ thick stainless steel can be Kasto saw cut. Kasto plate sawing is a cold process, and is ideal for parts that require that the cut edges be machined.
    Plate Laser
    Stainless steel plates can be laser cut thru 1-1/8″ thick. Stainless steel plates in excess of 120″ wide and thru 60′ long can be processed.
    Plate Shears
    Shear cutting stainless steel plate is a cost competitive option for processing stainless steel plate products. Stainless steel plates can be processed up to 3/4″ thick.
    Gauer Processing
    Stainless steel sheared and edged bar can be gauer processed from 1/8″ thick thru 5/8″ thick up to 8″ wide. Upon request, stainless plate can be gaurer processed thru 3/4″ thick.
    Machine Cutting
    Stainless steel rings and discs can be machine cut from 1/2″ thick thru 12″ thick, up to 42″ in diameter. While rings or discs can be waterjet cut, machine cutting stainless steel plate offers price advantages while still providing a clean machine-ready finish similar to waterjet cutting.
    Stainless Plate Leveling
    In house plate leveling of coil from 13 gauge stainless sheet thru 3/8″ stainless plate coil, thru 78.75″ wide (2 meter). We can provide non-standard stainless steel plate lengths–exceeding 40 in length. Leveling stainless steel coil to the exact lengths, reduces scrap, handling and secondary processing.

    Value Added Resources

    Stainless Steel Plate Polishing
    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 plates can also be cut to size. Pitt free surfaces can also be provided.
    Stainless Steel Plate Beveling
    Stainless can bevel the edges of stainless steel plate to prepare for welding or other processes.
    Blanchard grinding
    Stainless steel plate flatness in critical in certain applications. Penn Stainless can provide blanchard grinding of stainless steel plates upon customer request.
    Heatreating & Annealing
    Some grades of stainless steel plates 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
    Positive Material Identification (PMI)
    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.
    UT Testing
    In some cases, UT testing of the stainless steel plates may be required. We can assist you with this requirement.

    Flatness Tolerances of Plate Mill Plate:
    • Tolerance in this table apply to any length, not necessarily the rolling direction, up to 36 in. (914 mm) of the longer lengths in the plane of the plate measured while the plate rests on a flat surface with the concavity of the curvature upward.
    • If the longer dimensions are under 36 in. (914 mm), the tolerance is not greater then 1/4 in. (6.4mm).
    • For plates with specified minimum yield strengths of 35 ski (240 MPa) or more, the permitted variations are increased to 1 1/2 times the amounts shown.
