316 stainless steel was once the main choice for medical implants. 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. AISI ASTM 316 stainless steel properties such as physical properties, mechanical properties, magnetic properties are summarized in the tables below. 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. The corrosion resistance of molybdenum-bearing 316L austenitic steel is particularly effective in chloride-ion environments. endobj /Contents 18 0 R << 3 0 obj 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. stream Corrosion resistance is improved, particularly against sulfuric, hydrochloric, acetic, formic and tartaric acids; acid sulfates and alkaline chlorides. Warm seawater can corrode the surface of 316 grade marine parts over time, leaving the finish stained brown and rough. 316 stainless steel offers superior protection against hydrochloric, acetic, tartaric and sulfuric acids. This is easy to remember, as the L stands for "low." 2 0 obj This data sheet applies to stainless steel 316 / 1.4401 hot and cold-rolled sheets/plates and strip, semi-finished products, rods, rolled wire and profiles as well as seamless and welded tubes and pipes for pressure purposes. It’s the chromium in the 304 and 316 grades that differentiate stainless steel from carbon steel. The tacks should be subsequently grinded or at least be free from crater cracks. endobj Type 316L is an extra-low carbon version of Type 316 that minimizes harmful carbide precipitation due to welding. This usually occurs at temperatures above 140° F. The 316 grade also remains structurally strong even at sub-zero temperatures. We cannot give warranty for the results of processing and application of the products. CMC The higher Nickel content in 316 and 316L over SS 304 and the Molybdenum addition in 316 and 316L gives it an edge in performance in corrosive and high temperature environments. /Count 13 In this article the significance of these different properties will be covered with a view to enabling a fuller and better appreciation of the vast amount of pub-lished data which is available. When welding 1.4401 all procedures, which work against this distortion (eg. The passivated chromium oxide film which develops on the surface acts as a protective barrier against corrosion. 9.4 Btu-in./ft.2hr.-°F (100°C) / 16.2 W/m-K (100°C), Typical mechanical properties are based on AK source, ASTM A240, Tensile Strength Min (UTS) This steel has an extensively higher coefficient of thermal expansion as non-alloyed steel. 316L Stainless Steel INDUSTRIAL GRADE MATERIALS FOR 3D PRINTING ExOne.com Revised 8/19/19 Note: Typical expected properties. 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. Especially, they can be welded without any further preparation. It looks very similar to 304 stainless steel, and the two can only be differentiated by material testing. 1.4401 is very suitable for laser beam welding (weldability A 9in accordance with DVS bulletin 3203, part 3). 316 is an austenitic chromium nickel stainless steel containing molybdenum. It has excellent drawdown workability and holds a better strength at higher temperatures than the 304 grade. Copper back-up plates for faster heat rejection are functional, whereas, to avoid cracks in the solder metal, it is not allowed to surface-fuse the copper back up plate. /Type /Page It comes in a range of attractive finishes and withstands repeated cleaning well with detergents. /Type /Catalog << endobj /Font 19 0 R For product thicknesses over 12mm the double-V butt weld has to be preferred instead of a single-V butt weld. 8.9 x 10-6 microinches/in.-°F (32-212°F) / (16.0 μm/m-°C) (0-100°C), Electrical Resistivity Stainless steel 316 - 1.4401 is one of the many grades that thyssenkrupp Materials (UK) supply. We supply a vast range in various forms of stainless, aluminium and mild steel. The resistance to intergranular corrosion is guaranteed for larger product thicknesses in the welded condition. To avoid overheating or burn-through of thinner sheets, higher welding speed has to be applied. After pickling a carefully flushing with water has to be done. An accumulation of weld seams should be avoided. 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. << While processing only stainless tools like steel brushes, pneumatic picks and so on are allowed, in order to not endanger the passivation. The molybdenum component prevents chloride ions pitting the and crevassing the surface of the steel. Phone: Carbon Steel, Red Metals, and Other Punched Circles. However, with careful maintenance the finish can be restored to its original clean, bright condition. • 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. The molybdenum in 316L stainless steel also protects it against aggressive, acidic environments. >> /Annots 16 0 R Industries supplied include: exhaust manifolds, furnace parts, heat exchangers, jet engine parts, pharmaceutical and photographic equipment, valve and pump trim, chemical equipment, digesters, tanks, evaporators, pulp, paper and textile processing equipment, parts exposed to marine atmospheres and tubing. Also, 316 stainless steel contains between 2 – 3% molybdenum to give it its chloride-fighting properties. Pickling of the previously brushed seam area is carried out by dipping and spraying, however, often pickling pastes or solutions are used. Information given in this data sheet about the condition or usability of materials respectively products are no warranty for their properties, but act as a description. Annealing colours, scales, slag residues, tramp iron, spatters and such like have to be removed, in order to not destroy the passive layer. Industries supplied include: exhaust manifolds, furnace parts, heat exchangers, jet engine parts, pharmaceutical and photographic equipment, valve and pump trim, chemical equipment, digesters, tanks, evaporators, pulp, paper and textile processing equipment, parts exposed to marine atmospheres and tubing. xڥ\Yo9�~7����J+�7��݆gֻ��hi���TJ�j'U��*���~"xYgca�N~�`Fɸ�4�b��_������o������Z�u�\!����H �@Lx0�Rt�����_���o�v^��@���,� yu���_�����onX�. With a welding groove width smaller 0.3mm respectively 0.1mm product thickness the use of filler metals is not neccessary.
