IntroductionThe Atlas Wire & Bar MillThe Atlas Wire and Bar mill was opened in 1962 and since then has played animportant role in the Australian and New Zealand manufacturing industry as asupplier of specialty metal wire and bar product. Today the mill remains as theonly commercial operated mill of its type in this region of the world.Rod, wire & barThe definitions for rod, wire and bar are universally agreed, but in general canbe described as follows:Rod is the hot rolled feed produced in coil and purchased by the down streamdrawers, such as the Atlas Wire and Bar Mill. This product is then cold drawndown to wire or bar with diameters, properties and finishes suitable for furtherprocessing in industrial applications.Wire is typically supplied as coil and bar is supplied as straightened and cutlengths.Atlas Wire & Bar facilities & processesThe Atlas Wire and Bar Mill draws down coiled stainless and high-speed steelwire rod until the wire or bar diameter meets the customer’s required diameter,mechanical properties and finish.The minimum diameter of wire rod supplied to Atlas is 5.5mm and the AtlasWire and Bar Mill is capable of drawing wire and bar down to diametersbetween 1mm and 16mm.An overview of the Atlas Wire and Bar Mill processing line is shown in thediagram below:Inorganic salt coating bathWire rodMulti die wire drawing3 www.atlasmetals.com.au

IntroductionThe wire rod is delivered to Atlas’ bar and wire mill where it is plunged intoan inorganic salt coating bath and then baked in preparation for the drawingprocess. Once the coated wire rod has dried, it is fed through a series of multiholeand some single-hole wire drawing machines, which reduce the wire rodto the required diameter.Strand annealing Furnace Quenchingand coatingThe wire can also be heat treated (annealed) to soften it, making it moremalleable. The wire is fed through a furnace, where it is heated, quenched inwater and coated. It may then be drawn again to the exact diameter requiredby the customer.4 www.atlasmetals.com.au

Stainless steel wire and barWire & bar productsWire and bar is produced to meet the demands of many industries, in thefollowing broad categories:-- Weaving wire for manufacture of woven and welded screens and belts.- Forming wire for a vast array of clips, handles, frames, rings and brackets, instrengths from annealed through intermediate tempers to full hard.- Cold heading wire for production of corrosion resistant fasteners includingroofing screws, self tapping screws, bolts, set screws, nails, rivets and staples.- Spring temper wire - a very high strength wire used in production of corrosionresistant coiled springs.- Special Products such as flattened wire, can be produced to customerrequirements.- Bar in standard bright drawn and polished condition in standard or specialdiameters. High strength bar or other cut length products with special technicalrequirements can also be produced.Grades availableStainless steel wire and bar is available in standard grades 302HQ, 303, 304, 316,316L, 416 and 430, and a range of other grades specific to particularindustries as required.

Cold heading wireThe usual grades produced are 302HQ and 316. A much lesser quantity of 430 isproduced for heading applications. All of these grades are suitable to producethe full range of headed fasteners including cross recess pan-heads and crossrecess counter-sunk heads.Type 304 is used in some applications where the degree of cold forming is notas severe or where a higher strength fastener is required, such as some nails andself drilling screws.Heading wire is normally supplied with a final light “skin pass” draw, althoughthat destined for very severe cold heading operations can be “annealed at finalsize” - this is the softest possible condition.The most popular coating is Atlas “Supercoat”, which is a mixture of aninorganic salt carrier coating into which the wire is dipped, plus some residualdrawing soap. This coating is subject to damage by handling and by theenvironment, particularly by water. If well looked after, its life expectancy is inexcess of six months and is usually well over a year. Some simple heading jobssuch as nails and hinge pins do not require supercoat; normal Cold Drawn orBright Drawn finishes are acceptable.Coil sizes and weightsCatchweight coilsDiameter Coil weight Nominal coil I.D.(mm) (kg) (mm)1.51 - 2.00 30 - 75 4602.01 - 3.50 35 - 80 5603.51 - 5.00 40 - 100 5605.01 - 7.00 50 - 200 560Over 7.00 50 - 200 620Note: Random weights between the limits shown; 10% of the number of coils may be up to 50% below the stated minimum weight.Specified coil weights or sizes may be available subject to prior agreement.Stem packsDiameter Coil weight Nominal coil I.D.(mm) (kg) (mm)Up to 6.00 Up to 1000 460Diameter tolerancesDiameter(mm)Standard tolerance(mm)Note: Other tolerances may be available on request.1.51 - 8.00 plus 0.03, minus 0Over 8.00 plus 0.04, minus 09www.atlasmetals.com.au

Spring wireSpring wireTypes 304 and 316 are the two most common grades used for spring wire.The spring coating is usually left on the wire to assist spring making; this is thesame coating as “supercoat” left on heading wire. Imported spring wire mayalternatively be either nickel plated or “resin” coated (a very thin transparentcoating of PVC).Coated wire is essential for spring coiling. Very tightly wound springs,particularly of large diameter wire, tend to be most demanding of coatings.Atlas use special versions of Types 304 and 316 for spring wire. These havecarefully controlled analysis ranges to ensure the required tensile strengthvalues are obtained.Spring temper wire has the highest tensile strength of any of the stainless steelwires; the standard strength is in conformance with ASTM A313M, as listed laterin this section, but wire can be supplied to conform with other specifications,such as JIS G4314, if required.Coil sizes and weightsCoil NominalDiameter Weight Coil I.D.(mm) (kg) (mm)1.00 - 1.50 20 - 50 4001.51 - 2.50 30 - 75 5602.51 - 3.50 35 - 80 5603.51 - 5.00 40 - 100 5605.01 - 7.00 50 - 200 560Over 7.00 50 - 200 620NoteRandom weights between the limits shown; 10%of the number of coils may be up to 50% belowthe stated minimum weight.

CoatingStandard coating is Atlas “Spring Coat”, to assist in spring forming. By specialarrangement wire may be supplied bare to assist with soldering. Spring coat canif necessary be removed by immersion in hot alkaline detergent.Straightened and cut lengthsSpring temper wire in the diameter 1.6mm to 10mm can be supplied asstraightened and cut bar lengths, with tensile strength specifications of 90% ofthe values in the previous table.Stress reliefSpecial requirementsStress relief of finished springs in the temperature range of approximately 200-400˚C can improve their elastic properties. Higher temperatures will result inpermanent softening and (above 450˚C) carbide precipitation. Thesetemperatures must be avoided.Atlas Specialty Metals Technical Department should be consulted with regard toany special requirements in respect of application or specification, bytelephoning Free-Call 1800 818 599.13www.atlasmetals.com.au

Weaving wireTypes 304 and 316 and some 430 are used in a variety of tensile strengths,diameters and coatings for weaving. These wires find many applications inmining and processing screens and mesh link belts for mineral processing, heattreatment and in the food industry.Specific tensile strengths can be produced to customers’ requirements; about 1/4Hard or 1/2 Hard wire is usually produced (usually 900-1100 MPa or 1000-1200MPa). Cast and helix may also be specified for some applications. A range ofstandard weaving wires is available ex-stock.14 www.atlasmetals.com.au

General informationWire cast & helixThe “cast” and “helix” are important features of the finished wire and definehow well it is “killed” (not to be confused with “killed” carbon or low alloysteel, where killing refers to the deoxidation practice used in melting the steel).These properties are observed by cutting a single lap from the final coil andlaying it on a flat surface. The cast is the natural loop diameter which this freelap takes up; the helix is the difference in height between its two cut ends i.e.how much of a rise is present. Zero helix is if the lap lies perfectly flat. The idealis a cast equal to the coil diameter and nil helix. Particular requirements for castand helix should be discussed at time of order.Heat treatmentThe following heat treatments are recommended, refer AS2837-1986.AnnealingGrade Annealing temperature (ºC) CoolingAustenitic“300 Series” 1000 - 1100 rapidMartensitic410 820 - 900 slow416 820 - 900 slow420 840 - 900 slow431 620 - 660 slowFerritic430 750 - 820 air cool430F 750 - 820 air cool18www.atlasmetals.com.au

All of the 300 seriesgrades and the 400 series grades containing 16% or more chromium (except freemachining grades such as 303) may be satisfactorily passivated in a 20-50% byvolume solution of nitric acid at temperatures ranging from 50-70ºC for periodsfrom 10-30 minutes. Care must be taken when passivating the straightchromium grades containing 12-14% chromium (e.g. Type 410). A solutioncontaining 20-50% nitric acid should be used. The temperature range should bebetween 40 and 55ºC. Full details of pickling and passivation procedures can befound in ASTM A380, in the Technical Handbook or at the Atlas Speciality Metalswebsite.19www.atlasmetals.com.au
