It has excellent corrosion resistance in ordinary atmospheric conditions, but also has excellent corrosive resistance to more arduous environments such as salt water and environments where resistance to chloride corrosion is required. Steel with the material number AISI 316L (1.4404) is a frequently used chromium-nickel stainless steel with molybdenum addition and its alloy identifier X2CrNiMo17-12-2.It is attributed to the austenite group. The Filapina guys think they can just weld it with stick or tig, with their version of stainless wire or stick??? Compared to the common variant AISI 304 (1.4301), it is particularly distinguished by its increased properties concerning corrosion resistance. Owned and operated by AZoNetwork, © 2000-2021. Due to the addition of Molybdenum (Mo), SS 316 has a great improvement in corrosion resistance and certain properties. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. Cost is very similar, and both are durable, corrosion-resistant, and a good choice for high-stress situations. AISI Type 316/316L Stainless Steel, annealed, cold drawn, round Most of the hardness 316l stainless steel are malleable and have low density, which gives designers, engineers, contractors, and metal molding specialists the flexibility to create multiple custom solutions.

Grade 316L is more resistant to carbide precipitation and can be used in the above temperature range. In many marine environments, 316 does exhibit surface corrosion, usually visible as brown staining. Our welders always used 316L filler wire using Mig argon gas to weld 316L, is there any other way to weld it, to retain the corrosion resistance at the weld? Manufactured by the electri-furnace process, 316/316L meets the exacting standards of the aircraft industry. Possible alternative grades to 316 stainless steel. Properties quoted below are guideline figures only and should not be used for any design purposes. Thus it is extensively used in heavy gauge welded components (over about 6mm). Post-work annealing should be carried out to remove internal stresses. Whilst performing well when exposed to relatively high temperatures, this grade of stainless steel like most austenitic stainless grades also maintains its strength and toughness at sub-zero temperatures, making this an excellent choice for various applications and industries sectors such as oil & gas, water treatment, petrochemical and construction. There is commonly no appreciable price difference between 316 and 316L stainless steel. Balls are provided in the passivated condition. Alloy 316/316L is ideally suited for applications requiring corrosion resistance superior to Type 304 and has good elevated temperature strength. It also offers resistance to corrosion in polluted marine applications. This is particularly associated with crevices and rough surface finish. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures. Continuous use of 316 in the 425-860 °C range is not recommended if subsequent aqueous corrosion resistance is important. 0.03 max. If exact equivalents are needed original specifications must be consulted. These properties are specified for the flat-rolled products (plate, sheet, and coil) in ASTM A240/A240M. Do you have a question you'd like to ask regarding this article? AZoM speaks with Dr. Jean-Christophe Leroux, Professor of Drug Formulation and Delivery at ETH Zurich.
