Alloys 316 (UNS S31600) and 316L (UNS S31603) are molybdenum-bearing austenitic stainless steels, which are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Alloy 316L. These alloys also offer higher creep, stress-to-rupture, and tensile strength at elevated temperatures. In addition to excellent corrosion resistance and strength properties, the Alloys 316 and 316L Cr-Ni-Mo alloys also provide excellent fabricability and formability which are
typical of the austenitic stainless steels.
The material has superior welding and forming qualities. Grade 316 will require post-weld annealing to promote maximum corrosion resistance, though this is not necessary if Type 316L is used.
Origins from the Paper Industry
The steel was initially produced for the paper producing industry as it has been shown to be highly resistant to the sulphur compounds used in paper processing.
Typical applications for this material are now widespread due to its superior corrosion resistance properties when compared to Grade 316L. Type 316 stainless can be found in heat exchangers, pharmaceutical equipment, dairies and breweries, marine fittings, coastal architectural fascia and fittings and in food preparation areas.
316 & 316L steel plate and Plates have common properties and are often stocked with Dual Certification, where it is determined that both have properties and composition which comply with both steel types.
Type 316H is excluded from this scenario by virtue of the fact that unlike 316 & 316L, 316H is engineered to work in elevated working temperatures.

Resistance to Corrosion of ASTM A240 TP 316L Stainless Steel Plates
Alloys 316, 316L, and 317L are more resistant to atmospheric and other mild types of corrosion than the 18-8 stainless steels. In general, media that do not corrode 18-8 stainless steels will not attack these molybdenum-containing grades. One known exception is highly oxidizing acids such as nitric acid to which the molybdenum-bearing stainless steels are less resistant.
Intergranular Corrosion of ASTM A240 TP 316L Stainless Steel Plates
Both Alloys 316 and 317L are susceptible to precipitation of chromium carbides in grain boundaries when exposed to temperatures in the 800 to 1500°F (427 to 816°C) range. Such "sensitized" steels are subject to intergranular corrosion when exposed to aggressive environments. Where short periods of exposure are encountered, however, such as in welding, Alloy 317L with its higher chromium and molybdenum content, is more resistant to intergranular attack than Alloy 316 for applications where light gauge material is to be welded. Heavier cross sections over 7/16 inch (11.1 mm) usually require annealing even when Alloy 317L is used.

Physical Properties of 316 Stainless Steel Plates
When properly annealed, Alloys 316 and 317L are primarily austenitic. Small quantities of ferrite may or may not be present. When slowly cooled or held in the temperature range 800 to 1500°F (427 to 816°C), carbides are precipitated and the structure consists of austenite plus carbides.

The overall heat transfer coefficient of metals is determined by factors in addition to thermal conductivity of the metal. The ability of the 18-8 stainless grades to maintain clean surfaces often allows better heat transfer than other metals having higher thermal conductivity.
Specific Heat of ASTM A240 TP 316L Stainless Steel Plates
Magnetic Permeability of ASTM A240 TP 316L Stainless Steel Plates
Austenitic stainless steels are non-magnetic in the annealed, fully austenitic condition. The magnetic permeability of the Alloys 316 and 317L in the annealed condition is generally less than 1.02 at 200 H (oersteds). Permeability values for cold deformed material vary with composition and the amount of cold deformation but are usually higher than that for annealed material.

Impact Resistance of ASTM A240 TP 316L Stainless Steel Plates
The annealed austenitic stainless steels maintain a high level of impact resistance even at cryogenic temperatures, a property which, in combination with their low temperature strength and fabricability, has led to their extensive use in cryogenic applications. Representative Charpy V-notch impact data for annealed Type 316 at room temperature are shown below.

Heat Treatment of ASTM A240 TP 316L Stainless Steel Plates
The austenitic stainless steels are provided in the mill annealed condition ready for use. Heat treatment may be necessary during or after fabrication to remove the effects of cold forming or to dissolve precipitated chromium carbides resulting from thermal exposures. For the Alloys 316 and 317L the solution anneal is accomplished by heating in the 1900 to 2150°F (1040 to 1175°C) temperature range followed by air cooling or a water quench, depending on section thickness. Cooling should be sufficiently rapid through the 1500 to 800°F (816 to 427°C) range to avoid reprecipitation of chromium carbides and provide optimum corrosion resistance. In every case, the metal should be cooled from the annealing temperature to black heat in less than three minutes.
Alloys 316 and 317L cannot be hardened by heat treatment.

The austenitic stainless steels, including the Alloys 316 and 317L, are routinely fabricated into a variety of shapes ranging from the very simple to very complex. These alloys are blanked, pierced, and formed on equipment essentially the same as used for carbon steel. The excellent ductility of the austenitic alloys allows them to be readily formed by bending, stretching, deep drawing, and spinning. However, because of their greater strength and work hardenability, the power requirements for the austenitic grades during forming operations are considerably greater than for carbon steels. Attention to lubrication during forming of the austenitic alloys is essential to accommodate the high strength and galling tendency of these alloys.
Welding of ASTM A240 TP 316L Stainless Steel Plates
The austenitic stainless steels are considered to be the most weldable of the stainless steels. They are routinely joined by all fusion and resistance welding processes. Two important considerations for weld joints in these alloys are (1) avoidance of solidification cracking, and (2) preservation of corrosion resistance of the weld and heat-affected zones.
Fully austenitic weld deposits are more susceptible to cracking during welding. For this reason, Alloys 316, 316L, and 317L "matching" filler metals are formulated to solidify with a small amount of ferrite in the microstructure to minimize cracking susceptibility.
