316 stainless steel properties pdf
November 13th, 2020

Like its 304 grade counterpart, 316 stainless steel is non-magnetic and will not harden under heat treatment. 2 0 obj Another widely used austenitic steel is 316 and 316L stainless steel, the corrosion performance of SS 304 is not enough, 316L is often consider as the first alternate. /Count 13 Types 316, 316L, 317 and 317L are available in the form of sheet, strip and plate to ASTM A240 and ASME SA-240 and other pertinent specifica-tions. The enclosed documents are for information only and cannot replace reference to either EN 10088, or EN 10095. These days titanium, which offers better biocompatibility, is preferred. For cleaning the surface the processes brushing, grinding, pickling or blasting (iron-free silica or glass spheres) can be applied. For product thicknesses over 12mm the double-V butt weld has to be preferred instead of a single-V butt weld. 29.4 μ ohm.in / (74 μ ohm.cm), Thermal Conductivity The included angle should be 60° - 70°, when using MIG-welding about 50° are enough. In connection with a worse thermal conductivity, a greater distortion has to be expected. With larger welding grooves a similar filler metal can be used. An accumulation of weld seams should be avoided. The use of a higher alloyed filler metal can be necessary due to the cast structure of the weld metal. Standard welding processes for this steel grade are: When choosing the filler metal, the corrosion stress has to be regarded, as well. The tacks should be subsequently grinded or at least be free from crater cracks. << Stainless steel 316 - 1.4401 is one of the many grades that thyssenkrupp Materials (UK) supply. >> << >> /Type /Pages Their fusion point is lower than that of non-alloyed steel therefore austenitic steels have to be welded with lower heat input than non-alloyed steels. 2401 W Grant Avenue Bellwood, IL 60104 You’ll also find it used for chemical processing and laboratory equipment, condensers, and evaporators. The information, we give on for advice, comply to the experiences of the manufacturer as well as our own. /ProcSet [/PDF /Text] There are a few distinct differences with the quantities of chromium (18 – 20% for 304, 16 – 18% for 316) and nickel (8 – 10.5% for 304, 10 – 14% for 316). The L stands for low carbon, both L grades contain a maximum 0.03% carbon, while the standard grades can comprise up to 0.07% carbon. Stainless steel is generally suitable for many processing and related industries, but 316 stainless steel is unique. Also, 316 stainless steel contains between 2 – 3% molybdenum to give it its chloride-fighting properties. The high corrosion resistance of this stainless steel is based on the formation of a homogeneous, compact pasisve layer on the surface. In quenched condition the material can be slightly magnetizable. 28.0 x 103 ksi in tension / (193 x 103MPa in tension), Coefficient of Expansion In addition to the above, we also have datasheets that detail the mechanical properties and chemical composition of the following stainless steel grades. /Parent 2 0 R The chemical composition of stainless steel 316 is almost identical to that of the 304 grade. 19 0 obj >> strength properties, the Types 316, 316L, 317 and 317L Cr-Ni-Mo alloys also provide the excellent fabricability and formability which are typical of the austenitic stainless steels. The molybdenum component prevents chloride ions pitting the and crevassing the surface of the steel. 1 0 obj However, with careful maintenance the finish can be restored to its original clean, bright condition. 8.9 x 10-6 microinches/in.-°F (32-212°F) / (16.0 μm/m-°C) (0-100°C), Electrical Resistivity %���� helum as inert gas, the welding seam is as corrosion resistant as the base metal. The resistance to intergranular corrosion is guaranteed for larger product thicknesses in the welded condition. The keen resistance of 316L stainless steel to potable water and the alkalis and acids in food, make it ideal for use in restaurant kitchens. To avoid overheating or burn-through of thinner sheets, higher welding speed has to be applied. It looks very similar to 304 stainless steel, and the two can only be differentiated by material testing. AISI ASTM 316 stainless steel properties such as physical properties, mechanical properties, magnetic properties are summarized in the tables below. Common applications include pressure vessels, heat exchangers, exhaust manifolds and food preparation equipment. Molybdenum is a key ingredient in 316 stainless steel because it prevents small carbide particles that weaken the Chromic Oxide layer on the surface of the steel from forming at grain boundaries of the base metal. << ExOne disclaims all warranties and liabilities for the content hereof and makes no representations as to its accuracy or fitness for use for any purpose. Due to the Mo-content, good resistance against media containing chlorides and non-oxidising acids. The following tables show AISI 316 grade stainless steel mechanical properties such as yield strength, tensile strength, elongation and hardness, etc. • Mechanical properties of stainless steels (flat products) • Physical properties of stainless steels The attached collection of data reflects inquiries directed to stainless steel development associations. << /Filter [/FlateDecode] properties of stainless steels Type 304L and Type 316L are given for temperatures from 300 to 3000 K. The properties in the solid region were obtained by extrapolating available experimental data to the melting range, while appropriate correlations were used to estimate these properties in the liquid region. For a little extra cost, 316L stainless steel offers greater strength and durability in chloride-ion environments than the 304 grade. CMC While choosing an applicable process the fusion cut edges can be converted directly. Printable PDF: 316L Stainless Steel Alloy Data sheet. As with the 304 grade, 316 stainless steel owes much of its corrosion resistance to its chromium content. For brushing only stainless steel brushes can be used. Cost is very similar, and both are durable, corrosion-resistant, and a good choice for high-stress situations. This data sheet gives you more detailed information about the chemical and mechanical properties and is available as a pdf … This addition increases general corrosion resistance, improves resistance to pitting from chloride ion solutions, and provides increased strength at elevated temperatures. We cannot give warranty for the results of processing and application of the products. As such, the food and beverage industries are major customers. A hot crack hazard for the welding seam does not exist, when choosing an applicable process. We supply a vast range in various forms of stainless, aluminium and mild steel. 17 0 obj
