Good ductility with a high fatigue strength in marine applications. The alloy demonstrated good corrosion resistance characteristics for both uniform corrosion and localised corrosion. They aren’t as complicated as they might seem. Duplex alloy with a high strength to weight ratio, with superior abrasion and cavitation resistance. Published industry accepted corrosion rates for C276 and C22/Alloy 22. Super duplex stainless steel tubing and tube fittings tend to be stronger than standard stainless steel and offer first-rate resistance to localized corrosion. The omission of tungsten and a reduction in the iron content to increase thermal stability: virtually eliminating the intermetallic phases and grain boundary precipitation of the intermetallics and metallic carbides (mu phase). Duplex Steel Material has a metallurgical structure that comprises of two stages, 50% austenitic stainless steel and ferrite (body focused cubic cross section) in generally measure up to extents. Hastelloy C-276 alloy can be forged, hot-upset and impact extruded. Hastelloy C-276 HASTELLOY C-276 alloy is a nickel-molybdenum-chromium wrought alloy that is generally used as corrosion-resistance. Hastelloy ® C-22™ belongs to the group of chrome-molybdenum-wolfram-alloys that are highly resistant to corrosion. Here is some more detailed information about the general chemical make-up of alloys, and their most important characteristics. C22 is also a registered trade name, therefore other producers supply the material as alloy 22. Difference Between Duplex and Inconel. Nitric Acid In the powerful oxidizing chemicals including nitric acid, commonly used molybdenum-free steels offer better corrosion resistance than molybdenum based steels. 14211 Westfair West Drive Houston, TX 77041, USA Toll-Free | 832.634.2000 Fax | 832-634-2099. That is when a custom-made solution will be the best option. Hastelloy c-276(Hastelloy C276) is among the more well known Hastelloy grades for general corrosion service. HCl.

HASTELLOY C276 sheet 0.044" thick in the heat-treated condition at 2050°F, rapid quenched, has an average olsen cup depth of 0.48". They both possess excellent mechanical strength, especially at high temperatures, and they are both highly resistant to corrosion and oxidation. The alloy resists formation of grain boundary carbides in the weld HAZ, making it suitable for most chemical process conditions in the as-welded condition. As an industry leader, we have expertise in a wide variety of industries and will always seek to provide the highest quality at the best possible price. As such, they have several key characteristics in common. Results based on taking the average of a minimum of 10 mill test certs/heats. Hastelloy B-3 is the alloy in the Hastelloy family that shows best resistance to hydrochloric acid. Hastelloy C22, also known as alloy C22, is a versatile austenitic nickel-chromium-molybdenum-tungsten alloy with enhanced resistance to pitting, crevice corrosion and stress corrosion cracking. COVID-19 Update : Hy-Lok USA is Open for Business. Duplex Stainless Steels is designated as UNS S31803, UNS S32205. The universal governing system for the alloys is the Unified Numbering System (UNS) number, where UNS N10276 governs alloy C276 and UNS N06022 governs alloy 22. Alloy C276 (UNS N10276) and alloy 22 (UNS N06022) meet all the composition requirements and characteristics as defined and specified by ASTM and ASME specifications. The first nickel–chromium–molybdenum-tungsten alloy was developed. Nickel is the most expensive, then copper and finally steel. Duplex Stainless Steel Plate for wholesale, ... High quality ASTM B575 Hastelloy C-276 Hastelloy Alloy from China, China's leading Hastelloy Alloy product, with strict quality control Hastelloy Alloy factories, producing high quality Hastelloy Alloy products. Development over the past 70 years of the “C” family of alloys has been focused on improvements in alloy metallurgy, in melting technology and in thermo-mechanical processing. This structure gives all of the Duplex Steel Grade innumerable features such as strength and increased corrosion resistance combined … Hastelloy® is a superalloy, meaning that it has higher strength than standard alloy materials. In the following graphs, the lines for C-276 alloy are compared with those of two popular, austenitic stainless steels (316L and 254SMO), and a lower-molybdenum nickel alloy (625), in hydrochloric and sulfuric acids. Other mills cannot use the word “Hastelloy®” and have their own naming system.

Not every job is created equal, and sometimes, you might have very specific operational parameters to consider. Contact us today to find out how we can save you money without having to compromise on quality. While the duplex-grade family includes a wide range of specific formulations, duplex S31803 (2205) and super duplex S32750 (2507) stainless steel are two of the most common. In these cases, talking to one of our experts about our range of special alloys would be a sound decision. Key alloying elements are chromium, molybdenum and tungsten. Mixed acid (sulphuric acid, hydrochloric acid, ferric chloride and cupric chloride) – oxidising salt boiling test. There is no pass or fail criteria for the tests. Due to our extensive knowledge of many large-scale industries, we will be able to recommend the right special alloy products for your particular needs. Moreover, in severe oxidising media, the alloy did not have enough chromium to maintain useful passive behaviour and thus, exhibited high uniform corrosion rates. Super Duplex UNS S32750 is the most common super duplex grade in the market. With the advent of a new melting technology, AOD (argon oxygen decarburisation) / VOD (vacuum – oxygen decarburisation), allowed the alloy to be manufactured with much lower carbon and silicon levels. Duplex-grade stainless steel alloys have ferritic/austenitic properties, giving these materials superior strength and excellent resistance to oxidation. Pitting is generally not an issue however crevice attack should be prevented. If you have any questions about any of our products or services, don’t hesitate to give us a call. Being all corrosion resistant alloys cost is the most important factor here. ASTM G28A and ASTM G28B corrosion tests are qualitative tests, developed to demonstrate that the material  has not been sensitised and  is therefore not subject to intergranular corrosion. Hastelloy C-276: HASTELLOY C-276 alloy is a nickel-molybdenum-chromium wrought alloy that is generally used as corrosion-resistance. We supply the most complete range of fine to heavy-gauge welding wire and brazing wire for in all AMS-grades and AWS-grades including titanium, cobalt, nickel, aluminum, magnesium, stainless steel, and steel alloys for aerospace, power, commercial and challenging applications world-wide.
