The cast materials Märker® Alloy 31 and Märker® Alloy 59 enable a range of new applications in pharmaceutical, chemical and petrochemical plants.
Lindlar, 06 February 2006 Schmidt + Clemens GmbH + Co. KG, a manufacturer of high-quality stainless steel system components, has acquired a license from ThyssenKrupp VDM to produce cast parts made of the alloys Alloy 31 and Alloy 59, and developed the current wrought form of the alloy into a material suitable for casting.
With the cast materials Märker® Alloy 31 and Märker® Alloy 59 S+C is now the first supplier able to deliver all required components of a chemical processing plant as finish-cast or centrifugally cast parts, either unfinished or finished to the component manufacturer’s specifications.
Up to now, Märker® Alloys 31 and 59 were available only as wrought materials. Thousands of tons are currently in use throughout the world e.g. in the form of sheet metal, band steel, piping, forged parts or wire. Cast parts made of the new alloys will primarily be used in standard pumps, fittings, agitators, protective sleeves for thermometers, longitudinal flanges for vessels, for example in components of shut-off and control devices or connecting flanges in contact with corrosive media.
Märker® Alloy 31 and Märker® Alloy 59 demonstrate the same positive characteristics as the familiar wrought materials, which have proved effective in chemical and petrochemical plants as well in onshore and offshore applications. For example, the US Navy specifies, and has approved, Alloy 59 for safety reasons. This means that all parts such as pumps and fittings which are in contact with media, as well as all connecting flanges, must be made from the specified material.
Märker® Alloy 31 is characterized in particular by its high corrosion resistance when in contact with inorganic acids and some organic ones, while Märker® Alloy 59 demonstrates a high resistance to numerous media, particularly those containing halogenides. The most interesting application for the new cast materials is in modern “multi-product plants.” These plants process a variety of different chemicals at different times, products for which the construction of a dedicated plant would not be profitable. In such plants, the solvents used for cleaning are often highly aggressive. The same is true for pharmaceutical plants. Consequently, the specification requirements include corrosion resistance to a wide range of substances, good cleaning capability, extremely smooth surfaces and prevention of product discolorations. Märker® Alloy 31 and Märker® Alloy 59 meet these requirements to a great extent.
Aside from chemical and pharmaceutical plants, these highly alloyed materials are also used in exhaust gas desulfurization systems, waste-water evaporation systems and acid gas pipe networks. Thanks to its high resistance to pitting, crevice and voltage corrosion, Alloy 31 is suitable for chemical processes using medium concentrations of sulfuric acid, including pickling baths and REA, as well as for use in seawater applications and in the paper and cellulose industries. Märker Alloy 59 is universally applicable in a number of chemical and pharmaceutical processes as well as in waste-gas scrubbers in fossil fuel-fired power plants and incinerator plants, as well as in the production of citric acid and other substances.
