316/316L is the most commonly used austenitic stainless steel in the chemical process industry. The addition of molybdenum increases general corrosion resistance, improves chloride pitting resistance and strengthens the alloy in high temperature service. Through the controlled addition of nitrogen it is common for 316/316L to meet the mechanical properties of 316 straight grade, while maintaining a 316 Stainless Bar & Rod Stock - 316 SS Bars (Hex, Round 316 and 316/L (UNS S31600 & S31603) are molybdenum-bearing austenitic stainless steels. The 316/316L stainless steel bar, rod and wire alloy also offer higher creep, stress to rupture and tensile strength at elevated temperatures, in addition to excellent corrosion resistance and strength properties. 316/L refers to the lower carbon content to allow for greater corrosion protection when welding.
The austenitic class of stainless steels is generally considered to be weldable by the common fusion and resistance techniques. Special consideration is required to avoid weld hot cracking by assuring formation of ferrite in the weld deposit. These particular alloys are generally considered to have poorer weldability than Types 304 and 304L. ASTM A240 304 Austenitic Stainless Steel - BEBON ASTM A240 304 Austenitic Stainless Steel is mainly used for manufacturing parts,acid conveying pipes,vessels by deep impacting.. 1.

Silicon is used as an alloy to promote oxidation resist-ance and resistance to corrosion by oxidizing acids. Copper is used to promote resistance to sulfuric acid. Rare earths make a more stably oxidation-resisting scale. Niobium increases Fig. 2 The austenitic stainless family. Source:Ref 3
Reference is often made to stainless steel in the singular sense as if it were one material. Actually there are over 50 stainless steel alloys. Three general classifications are used to identify stainless steels. They are:1. Metallurgical Structure. 2.

Black and White Liquor Vessels S31803, and S32304 Pulp and Paper Grade 316 Stainless Steel Austral WrightAustenitic stainless steels are inherently tough, maintaining the ductile fracture mode and high absorbed energy in impact tests to cryogenic temperatures (-200°C). Pressure Vessels AS1210, Pressure Vessels, allows the use of grade 316 up to a temperature of 800°C.

Jul 05, 2018 · Austenite refers to stainless steel containing chromium 18% above, nickel 8% around, as well as a small amount of molybdenum, titanium, nitrogen and other elements. The large amount of Ni and Cr contained within makes the steel structure austenitic under room temperature. The commonly used Austenitic grades are 1Cr18Ni9, 0Cr19Ni9 and the like.
