chromium-nickel austenitic stainless steels such as ATI 304. These alloys also offer higher creep, stress-to-rupture and tensile strength at elevated temperature. ATI 317™ and ATI 317L™ alloys containing 3 to 4% molybdenum are preferred to ATI 316™ or ATI 316L™ alloys which contain 2 to 3% molybdenum in applications requiring enhanced pitting and general corrosion resistance.
AISI 316 vs 316L Stainless Steel, Difference of SS316
Both AISI 316 vs 316L stainless steel are molybdenum (Mo) containing austenitic stainless steel grades. The main difference between 316 and 316L stainless steel is the level of carbon content, weldability, corrosion resistance and mechanical properties.

317L - Rolled Alloys, Inc.
317L is a molybdenum containing austenitic stainless steel, with improved corrosion resistance over 304/304L and 316/316L stainless steel. The increased levels of chromium, nickel and molybdenum over 316L stainless steel improve chloride pitting resistance and general corrosion.
Higher strength and hardness than other austenitic stainless steels such as Alloy 304, Alloy 316L & Alloy 317L Excellent ductility and toughness at both elevated and cryogenic temperatures Non-magnetic, even after severe cold working, making it suitable for sensor applications
Type 316 steel is an austenitic chromium-nickel stainless steel that contains between two and 3% molybdenum. The molybdenum content increases corrosion resistance, improves resistance to pitting in chloride ion solutions, and increases strength at high temperatures.
It has a moderately low electrical conductivity and a fairly low tensile strength among wrought austenitic stainless steels. The graph bars on the material properties cards below compare AISI 317L stainless steel towrought austenitic stainless steels (top), all iron
If there is a danger of intergranular corrosion 316L, the lower carbon form, is more resistant to carbide precipitation and should be considered. 316H provides greater strength at higher temperatures and is often used in high-pressure applications above 500oC. If there is a need to provide increased resistance to chlorides you should consider 316Ti.
These alloys also offer higher creep, stress-to-rupture and tensile strength at elevated temperature. Types 317 and 317L containing 3 to 4% molybdenum are preferred to Types 316 or 316L which contain 2 to 3% molybdenum in applications requiring enhanced pitting and general corrosion resistance.
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.
Forta H500 has a higher yield strength than Forta H400, making it a cost-effective and lightweight austenitic stainless steel for the automotive industry and other transport or construction applications.
temperature or at intermittently high temperature. For a prolonged service life, such as 20 years, plain carbon steels are usually limited to a maximum operating temperature of 750°F (399°C); the ½% molybdenum alloy steels to approximately 850°F (454°C); and the stainless steels to considerably higher temperatures depending upon the type used.
In terms of pitting resistance performance, 317 is higher than 304 and 316. The high molybdenum guarantees that 317L is more resistant to overall and local corrosion in most media, such as sulfuric acid, acid chlorine and phosphoric acid. However, 317L has poor corrosion resistance in strong oxidizing acids such as nitric acid.

317 is a higher chromium, nickel and molybdenum version of 316 stainless designed principally for increased strength and corrosion resistance when compared with 304/304L and 316/316L. 317L is similar to 316 stainless steel but provides improved resistance to atmospheric corrosion, to many organic and inorganic chemicals and to food and beverages and can produce stronger welds due to the low
317L is a molybdenum-bearing steel that offers a higher stress-to-rupture, creep, and tensile strength at elevated temperatures. 317L is a low carbon version of 317 and is non-magnetic in the annealed condition. 317L can often be found in pulp and paper plants, food processing plants, chemical and petrochemical processing equipment, and textile equipment.
Essentially similar to T-316; but the increased chromium, nickel and molybdenum content results in better corrosion resistance, higher tensile strength and higher creep strength than T-316. T-317L with .03% maximum carbon content is used to restrict carbide precipitation during welding and in applications where maximum corrosion resistance is required.
316/316L Stainless Steel Type 316/316L Stainless Steel is a molybdenum steel possessing improved resistance to pitting by solutions containing chlorides and other halides. In addition, it provides excellent elevated temperature tensile, creep and stress-rupture strengths.
