CREEP AND STRESS-RUPTURE STRENGTH<strong>HAYNES</strong> <strong>188</strong> <strong>alloy</strong> is a solidsolution-strengthenedmaterialwhich combines excellent hightemperaturestrength with goodtabricability at room temperature. It is particularly effectivefor very long-term applicationsat temperatures of 1200°F(650°C) or more. It is strongerthan nickel-base solid-solutionstrengthened<strong>alloy</strong>s, and farstronger than smple nckelchromium or iron-nicke -chromium heat-resistant <strong>alloy</strong>s.This can allow for significantsection thickness reductionwhen it is substituted for thesematerials.COMPARISON OF SHEET MATERIALS: STRESS TO PRODUCE 1% CREEP IN 1000 HOURSTEST TEMPERATURE15 750°c 800°C 850°c23010x9 625615 5600(0ft 32900°c 950°c iooo°c1009080 706050403020CtaC’)(0Ui(0100.9 I I1400°F 1500°F1600°F1700 F1800°FTEST TEMPERATURECREEP AND RUPTURE STRENGTHCOLD-ROLLED AND 2150°F (1175C) SOLUTION-ANNEALED SHEETTestApproximate Initial Stress, Ksi (MPa)TemperatureCreep,to Produce Specified Creep in:°F(°C)% 10 Hrs. 100 Hrs. 1,000 Hrs.1400(760) 0.5 22.5 (155) 16.4 (115) 11.7 (81)1.0 25.5 (175) 18.5 (130) 13.3 (92)Rupture 43.0 (295) 32.0 (220) 23.0 (160)1500(815) 0.5 15.5 (105) 11.1 (77) 7.8 (54)1.0 17.6 (120) 12.6 (87) 8.8 (61)Rupture 31.0 (215) 21.7 (150) 15.0 (105)<strong>HAYNES</strong> <strong>188</strong> <strong>alloy</strong> 4

THERMAL STABILITY<strong>HAYNES</strong><strong>®</strong> <strong>188</strong> <strong>alloy</strong> is similar tothe solid-solution-strengthenedsuper<strong>alloy</strong>s, such as <strong>alloy</strong> 625or HASTELLOY<strong>®</strong> X <strong>alloy</strong>, whichwill precipitate deleteriousphases upon such long termexposure. In this case, thephase in question is a C02Wlaves phase, which serves toimpair both tensile ductility andimpact strength. The behaviorof <strong>188</strong> <strong>alloy</strong> is significantly better in this regard than <strong>HAYNES</strong>25 <strong>alloy</strong>, which it replaced; butfor applications where thermalstability is important, 230° <strong>alloy</strong>is recommended.EXPOSURE TEMPERATURE (°C)AT 500 600 700 800 900 1000I I I I I I2 ~ .

WELDING<strong>HAYNES</strong> <strong>188</strong> <strong>alloy</strong> is readi ywelded by Gas Tungsten Arc(TIG), Gas Metal Arc (MIG),Shie ded Metal Arc (coatedelectrodes), electron beamwelding and resistance weldingtechniques. Its welding characteristics are similar to those for<strong>HAYNES</strong> 25 <strong>alloy</strong>. SubmergedArc welding is not recommended as this process ischaracterized by high heatinput to the base metal andslow cooIng of the weld. Thesefactors can ncrease weldrestraint and promote cracking.Base Metal PreparationThe joint surface and adjacentarea should be thoroughlycleaned before welding. Allgrease, oil, crayon marks, sulfur compounds and otherforeign matter should beremoved. Contact with copperor copper-bearing materials inthe joint area should beavoided. It is preferable, butnot necessary, that the <strong>alloy</strong> bein the solution-annealed condition when welded.Filler Metal SelectionMatching composition fillermetal is recommended for joining <strong>188</strong> <strong>alloy</strong>. For joiningsection thicknesses greaterthan 3/8 in. (9.5 mm) 230~Wwfiller wire is suggested. Forshielded metal arc welding,<strong>HAYNES</strong> 25 <strong>alloy</strong> electrodes(AMS 5796) are suggested. Fordissimilar metal joining of <strong>188</strong><strong>alloy</strong> to nickel-, cobalt- or ironbasematerials, <strong>188</strong> <strong>alloy</strong> itself,230-W filler wire, 556TM <strong>alloy</strong>,HASTELLOY S <strong>alloy</strong> (AMS5838) or HASTELLOY W <strong>alloy</strong>(AMS 5786, 5787) weldingproducts are suggested,depending upon the particularcase.Preheating, InterpassTemperatures and Post-WeldHeat TreatmentPreheat is not usually requiredso ong as base meta to bewelded is above 32 F (0°C).Interpass temperatures generally should be low. Auxiliarycooling methods may be usedbetween weld passes, asneeded, prov d ng that suchmethods do not introduce contaminants. Post-weld heattreatment is not normal yrequired for <strong>188</strong> <strong>alloy</strong>. For further information, please contact<strong>Haynes</strong> <strong>International</strong>.HEALTH AND SAFETY INERMATIONWelding can be a safe occupation. Those in the weldingindustry, however, should beaware of the potential hazardsassociated with welding fumes,gases, radiation, electricshock, heat, eye injuries, burns,etc. Also, local, municipal,state, and federal regulations(such as those issued byOSHA) relative to weldng andcutting processes should beconsidered.Nickel-, cobalt-, and iron-base<strong>alloy</strong> products may contain, invarying concentrations, the following elemental constituents:auminum, cobalt, chromium,copper, iron, manganese,molybdenum, nickel and tungsten For specificconcentrations of these andother elements present, refer tothe Materal Safety Data Sheets(MSDS) H3095 and H1072 forthe product.Inha ation of metal dust orfumes generated from weldng,cutting, grind ng, melting, ordross handling of these <strong>alloy</strong>smay cause adverse healtheffects such as reduced lungfunction, nasal and mucousmembrane irritation. Exposureto dust or fumes which may begenerated in working withthese <strong>alloy</strong>s may alsocause eye irritation, skin rashand effects on other organsystems.The operation and maintenance of welding and cuttingequipment should conform tothe provisions of AmericanNat onal Standard ANSI/AWSZ491, (Safely in Welding andCuffing”) Attention s especia y cal ed to Section 7(Protect on of Personnel) and 8(Heath Protect on andVentilat on) of ANSI/AWS Z491.Mechanical ventilation s advisable and, under certainconditions such as a very confined space, is necessaryduring welding or cuffing operations, or both, to preventpossible exposure to hazardous fumes, gases, or dustthat may occur.<strong>HAYNES</strong> <strong>188</strong> <strong>alloy</strong>
