The Alloys 316 and 317L exhibit excellent resistance to oxidation and a low rate of scaling in air atmospheres at temperature up to 1600 to 1650°F (871 to 899°C). The performance of Alloy 316 is generally somewhat inferior to that of Alloy 304 stainless steel tube which has slightly higher chromium content (18% vs. 16% for Alloy 316).
The molybdenum bearing Alloys 316 and 317L stainless steel also provide resistance to a wide variety of other environments. As shown by the laboratory corrosion data below, these alloys offer excellent resistance to boiling 20% phosphoric acid. They are also widely used in

Mar 19, 2015 · Steel is made of iron and carbon, and stainless steel contains iron, carbon, and anywhere from 12 30% chromium. Stainless steel can contain other elements such as nickel and manganese, but chromium is the key element which makes it rust resistant. When the surface of normal steel is exposed to oxygen,
Rust on AISI 316L. A. Two solutions, passivation or electropolish. Your problem is not the 316SS, but is the traces of iron smeared on the surface from your machining equipment. This rusts and then spreads. Stainless does not mean stain "proof" or rust proof. It is only "LESS" likely to rust than steel.
Class A4 USA Grade 316 F593. Grade A4 is also an Austenitic grade of 316 stainless steel, it has a higher corrosion resistance than A2 grade 316 stainless steel and this in many chemical environments. Class A4 USA Grade 316 F593 is highly advised to be used where installations are undergoing extreme operating conditions, including contact with dilute sulphuric acid, and acetic acid over a wide
Oxidation of alloy 310S in supercritical water was much lower than that of alloy 316L because of the formation of a protective layer of Mn 2 CrO 4 spinel on the surface. No protective scale was formed on the surface of the alloy 316L, as magnetite ( Fe 3 O 4 ) and iron chromium spinel ( FeCr 2 O 4 ) were the product of oxidation
Feb 26, 2018 · For a material to be considered stainless steel, at least 10.5% of the make up must be chromium. Additional alloys typically include nickel, titanium, aluminum, copper, nitrogen, phosphorous, selenium and molybdenum. The key difference between the 304 and the 316L is the addition of molybdenum in the 316L.
Penn Stainless inventory includes 316/316L (UNS S31600 / S31603), in sheet, sheet coil, plate, plate coil, bar, structural and tubular products. Generally, this grade is dual certified to meet both 316 and 316L. Alloy 316/316L is ideally suited for applications requiring corrosion resistance superior to Type 304 and has good elevated temperature strength.
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.
The most popular of the 300 series steels—304 stainless steel— is revered for its very good corrosion resistance and is commonly used in cookware. Martensitic stainless steels can be hardened via heat treatment; how hard they can get depends on their carbon content.
Stainless Steel 316 and 316L Grade 316 is the standard molybdenum bearing grade, second inoverall volume production to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.
AISI 316 Grade Stainless Steel (UNS S31600) ASTM AISI 316 stainless steel (UNS S31600) is one of the most widely used austenitic stainless steels. Due to the addition of Molybdenum (Mo), SS316 has a great improvement in corrosion resistance and certain properties. 316L stainless steel (UNS S31603) is
Jun 18, 2018 · Duplex stainless steels are so called because their metallurgical structure consists of two phases, austenite and ferrite in roughly equal proportions. They are used for their good mechanical properties in the as cast (and therefore as welded cond
316L Stainless Steel Technical Data Sheet. Type 316 is considerably more resistant than any of the other chromium nickel types to solutions of sulfuric acid. At temperature as high as 120° F (49° C), Type 316 is resistant to concentrations of this acid up to 5 percent. At temperatures under 100° F
Aug 18, 2017 · 304 stainless steel is made up of low carbon and chromium nickel content which makes it extremely versatile and widely used out of all the stainless steel options. The 304 option has proven to be resistant to corrosion and oxidation and offers a variety of appearances and finishes. 304 is commonly used in kitchen equipment, storage tanks
SAE 316L stainless steel. Its primary alloying constituents after iron, are chromium (between 16 18%), nickel (between 10 12%) and molybdenum (between 2 3%). The addition of molybdenum provides greater corrosion resistance than 304, with respect to localized corrosive attack by chlorides and to general corrosion by reducing acids, such as sulphuric acid.
