Content

317 stainless steel plate is an austenitic, molybdenum-bearing grade of stainless steel with increased resistance to chemical attack when compared to basic chromium-nickel alloy such as 304. Due to chemical composition of 317 stainless steel plate, this steel plate offers higher creep strength, stress to rupture and tensile strength, specifically at elevated temperatures. This 317 stainless steel plate is a low carbon grade which results in greater resistance to sensitization during welding and other important thermal processes.

 

The 317 stainless steel plate is available for purchase at HT PIPE in a variety of length, widths, and thicknesses. It can be purchased in plate mill plate thickness ranging between 0.188” and 1.0”. Other thickness and a variety of lengths and widths are available.

 

The Alloy 317L (UNS S31703) Plate is a low carbon corrosion resistant austenitic chromium-nickel-molybdenum stainless steel. The high levels of these elements assure the alloy has superior chloride pitting and general corrosion resistance to the conventional 304/304L and 316/316L grades. The alloy 2507 provides improved resistance relative to 316L in strongly corrosive environments containing sulphurous media, chlorides, and other halides.

 

The low carbon content of 317L stainless steel plate enables it to be welded without intergranular corrosion resulting from chromium carbide precipitation enabling it to be used in the as-welded condition. With the addition of nitrogen as a strengthening agent, the plate of this alloy can be dual certified as 317 (UNS S31700) stainless steel plate. Alloy 317L is non-magnetic in the annealed condition. It cannot be hardened by heat treatment; however the material will harden due to cold working. Alloy 317L can be easily welded and processed by standard shop fabrication practices.
