SPI stocks a huge variety of stainless steel grades, gauges and sizes—if we don't have it, we can get it.

Stainless Steel Plate Inventory

Stainless steel is manufactured in various raw forms. Whenever you make anything out of stainless, regardless of grade, you always start with the most economic form of one of these, depending on the desired finished product.

Stainless Processing, Inc. primarily focuses on cutting parts from stainless steel plate, 3/16" thru 6" thick.

When made from plate—as opposed to forged or cast steel—the grade of stainless steel determines some of the characteristics of the finished product. Stainless steel plate offers a variety of thicknesses and grades that possess different physical and chemical properties.

We keep an extensive inventory of prime ASTM A240/ASME SA240 stainless steel plate on hand, and all material may be cut to virtually any shape you require. See our processing section for a multitude of options.
