![]() It is also suited to stamping, heading and drawing but post work annealing is recommended to relieve internal stresses.Ĭold working will increase both strength and hardness of 316 stainless steel.Īll common hot working processes can be performed on 316 stainless steel. Grade 316 is readily brake or roll formed into a variety of parts. These precautions are necessary to avoid cross contamination of stainless steel by easily corroded metals that may discolour the surface of the fabricated product. Tooling and work surfaces must be thoroughly cleaned before use. Where high strength is required at temperatures above 500☌, grade 316H is recommended.įabrication of all stainless steels should be done only with tools dedicated to stainless steel materials. In this instance 316L is recommended due to its resistance to carbide precipitation. ![]() However, continuous use at 425-860☌ is not recommended if corrosion resistance in water is required. Grade 316 is also subject to stress corrosion cracking above around 60☌.ģ16 has good resistance to oxidation in intermittent service to 870☌ and in continuous service to 925☌. Warm chloride environments can cause pitting and crevice corrosion. It is usually regarded as “marine grade” stainless steel but is not resistant to warm sea water. Grade 316 has excellent corrosion resistance when exposed to a range of corrosive environments and media. Initially developed for use in paper mills 316 stainless steel is now typically used in: Stainless Steel Grade 1.4401/316 also corresponds to the following designations but may not be a direct equivalent: 316Ti retains physical and mechanical properties similar to standard grades of 316.Ĭhemical Composition Spec: EN 10088-2:2005 1.4401 Steel Chemical Element The main advantage of 316Ti is that it can be held at higher temperatures for a longer period without sensitisation (precipitation) occurring. This prevents carbide precipitation at the grain boundaries and protects the metal from corrosion. The titanium atoms stabilise the structure of the 316 at temperatures over 800☌. Titanium content is typically only around 0.5%. Stainless steel grade 316Ti contains a small amount of titanium. It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet. ASTM, EN or other standards may cover all products sold. Property data given in this document is typical for flat rolled products covered by EN 10088-2:2005. The austenitic structure of 316 stainless steel gives excellent toughness, even at cryogenic temperatures. This makes it suited to use in heavy gauge (over about 6mm) welded components.įor elevated temperature applications the high carbon variant, 316H stainless steel and the stabilised grade 316Ti stainless steel should be employed. This is particularly apparent for pitting and crevice corrosion in chloride environments.ģ16L, the low carbon version of 316 stainless steel, is immune to grain boundary carbide precipitation (sensitisation). Grade 316 is an austenitic grade second only to 304 in commercial importance.ģ16 stainless steel contains an addition of molybdenum that gives it improved corrosion resistance. Stainless steel types 1.4401 and 1.4404 are also known as grades 316 and 316L respectively. Quarto Plate is hot rolled plate over 12mm thick that has not been coiled during production.ĬPP is Continuously Produced Plate up to 12mm thick that has been coiled during rolling. 1.4401 (316) Sheet and Plate (Quarto Plate & CPP) ![]()
