1 MATERIALS FOR WOVEN WIRE LOTH HAVER & BOEKER

2 MATERIALS FOR WOVEN WIRE LOTH. Technical woven wire cloth manufactured by Haver & Boecker is used for screening and filtration in almost every industrial sector: chemical, plastic, automobile, aviation, aerospace, electronics, industrial screening (mining and quarrying), test sieving, food processing industry and a host of other applications. In addition to its technical properties, Haver & Boecker woven wire cloth has a high aesthetic appeal. Architects and designers started combining the two in the early 990s. The variety of wire mesh types offered by Haver & Boecker is as extensive as the range of applications. From 6 mm diameter wire, to fine wire down to only 0.0 mm diameter, we weave all types of material. n Steel: blank, galvanized, tinned, lacquered, plastic coated n Stainless steel: chrome steel, chrome-nickel steel, chromenickel-molybdenum steel, heat resisting steel n Non-ferrous metals: aluminium, nickel, MONEL-Metal, phosphor bronze, brass, copper n Special materials: titanium, hastelloy, silver, platinum und many others. The selection of material, quality and processing are of great importance for the properties of the woven wire cloth product. ertain requirements can be fulfilled only by using certain materials. Here the costs for various materials can vary widely. Knowledge about which materials are best suited for particular applications and which processes may be used are especially important for assuring the fulfilment of the requirements for function, stability, safety, and economy. On the following pages we present the individual materials. A table shows the chemical composition, density, resistance to air, sea water, lye, and acid, as well as tensile strength, heat conducting capacity, and electrical resistance. Using certified measurement and test procedures, proof is provided that the wire cloth from Haver & Boecker fulfils the respective requirements. Moreover, we have also developed our own processes for quality assurance. During the reception of wire materials, wire cloth production and before the delivery our laboratory conducts special analyses along with the classic material and quality checks. Our certified quality management system as to DIN EN ISO 900:008 provides additional assurance. In connection with differentiated quality assurance of incoming wire material until finished product as to DIN ISO 90 and DIN ISO 90, first class woven wire cloth quality is guaranteed. Haver & Boecker began producing wire cloth in Hohenlimburg, Germany, in 887. Today, we are one of the world s leading wire weaving companies with a global network of branches and manufacturing facilities. Our work is based upon experience, continuous research and development of our products and manufacturing processes, along with the knowledge and ability of our staff. This combination of tradition and innovation allows us to meet and exceed the high expectations of our customers.

4 Steel Plain, low carbon steel (iron) with little resistance to corrosion under normal environmental conditions. Haver & Boecker therefore offers woven wire cloth made from plain steel in galvanized, tinned or lacquered finish. HAVER NIA-Steel HAVER NIA-Steel is a spring steel with high carbon content and manganese elements. It is extremely resistant to abrasion and vibration and - at the same time - it is elastic. Therefore it is especially suitable for industrial screens. Martensitic and Precipitationhardening Stainless Steels The materials named in the table show a feritic microstructure and are magnetic. Using special heat treatment they can be hardened in order to achieve a higher wear resistance and stability. The chromium content of the alloy results in good corrosion resistance to normal environment conditions. Austenitic Stainless Steels Stainless Steel is the most widely used material for our woven wire, covering most applications. These alloys show very good resistance to corrosion under atmospheric conditions. Austenitic stainless steels are not resistant to high-temperatureoxidation. For high-temperature applications, when some discoloration of the surface can appear, i.e. over 0 (8 F), heat resisting steels should preferably be used. In cases where comparable corrosion properties are required with a higher strength, we recommend the material No..0. If the material is to be welded, we recommend austenitic stainless steels with a low carbon content or the material No..7, stabilized with titanium. Both show a sufficient resistance to intercrystaline corrosion. The material group... contains molybdenum and has a higher resistance to chlorous media than the material group... Austenitic-Ferritic Steels So-called compound steels with very good corrosion resistance to seawater. The alloy constituent molybdenum makes them resistant against pitting or selective corrosion. ompared to the austenitic alloys they have a high tensile strength, making them particularly suitable for applications of the chemical or petrochemical industry. Heat Resisting Steel and Heat onducting Alloys These steels are resistant to temperatures of up to,00 (,7 F) in air and show a good resistance to possible heat waste. The coat of aluminium-oxide that forms on the wire surface makes them especially suitable for applications in air. The use of ferritic steels in aggressive or sulphurous surroundings is not recommended. For such applications austenitic heat resisting steels should be used as they show a better resistance to high-temperaturecorrosion.

5 opper and opper based Alloys opper displays good conducting properties for heat and electricity. It is highly resistant in the atmosphere as well as in sea-water. The corrosion resistance to cyanides, halogenides and ammonia however is poor. opper-tin alloys (Phosphor Bronze) are largely wear and tear resistant and show good emergency running properties. This property is important in bearings. opper-zinc alloys (Brass) are particularly suitable for sieving and filtration purposes. It is important that the material does not come into contact with ammonia (NH ), because it may be destroyed by crevice corrosion. Titanium and Aluminium based Alloys Aluminium is a very soft and light material with good corrosion resistance. As for the austenitic materials the corrosion resistance results from a passivation coating that is formed in the air. ALMg and ALMg are alloyed with magnesium and have a higher tensile strength than highgrade aluminium (coat). Titanium is a material with very good corrosion resistance to a number of aggressive media. It is used in the air-, space- and medical industries. The excellent relation ship between tensile strength and density is comparable to austenitic materials. ckel und ckel based Alloys ckel is resistant to a number of corroding media such as halogenides, caustic alkalines and many organic compounds. It shows good magnetic-, electrical- and heat conducting properties. Woven wire cloth made from a nickel based alloy is produced to meet certain criteria. Special alloy constituents combine a high corrosion resistance to acids and lyes with temperature resistance. Alloy 9 offers a large application field in alkalines and acids. HAVER & BOEKER
