Standard Flanges

Stainless Plate Products produces a wide variety of flat face slip-on flanges (also known as hubless or plate flanges). These high quality plate flanges have a wide variety of applications.


  • Stainless steel plate flanges are produced from quality mill plate. Mill plate produced to the ASTM A240 and ASME SA240
    standards is virtually free of voids, non-metallic inclusions and other defects. The inherent corrosion resistance of
    stainless steel is enhanced by the superior grain structure offered by plate products over forged or cast products.
  • As companies begin to look at life-cycle costing models, in almost every case, the slightly higher initial cost of stainless steel plate flanges is more than offset by
    the extended service life and the reduction of the normal maintenance costs.
  • Stainless steel plate flanges are a widely accepted alternative to cast or forged flanges in low pressure applications.
