Outstanding Corrosion  Resistance In The AsWelded Condition  HASTELLOY?   B-3  ?   alloy is an  additional member of the  nickel-molybdenum family of  alloys with excellent resistance  to hydrochloric acid at all  concentrations and temperatures.  It also withstands  sulfuric, acetic, formic and  phosphoric acids, and other  nonoxidizing media.  B-3 alloy  has a special chemistry  designed to achieve a level of  thermal stability greatly superior to that of its predecessors,  e.g. HASTELLOY B-2 alloy.  B-3 alloy has excellent resistance to pitting corrosion, to  stress-corrosion cracking and  to knife-line and heat-affected  zone attack.  Fabrication  The improved thermal stability  of HASTELLOY B-3 alloy  minimizes the problems  associated with fabrication of  B-2 alloy components.  This is  due to the reduced tendency  to precipitate deleterious  intermetallic phases in B-3  alloy, thereby, affording it  greater ductility than B-2 alloy  during and following various  thermal cycling conditions.  HASTELLOY B-3 alloy has  good overall forming and  welding characteristics.  It may  be forged or otherwise hotworked, providing that it is  3 HASTELLOY?   B-3  ?   alloy  1950°F (1065°C) and rapid  quenched, except for bright  annealed sheet or coil products which are heat-treated at  2100°F (1150°C) and cooled in  hydrogen.  Available in Wrought  Form  HASTELLOY B-3 alloy is  available in the form of plate,  sheet, strip, billet, bar, wire,  pipe and tubing.  Applications  HASTELLOY B-3 alloy is  suitable for use in all applications previously requiring the  use of HASTELLOY B-2 alloy.  Like B-2 alloy, B-3 is not  recommended for use in the  presence of ferric or cupric  salts as these salts may cause  rapid corrosion failure.  Ferric  or cupric salts may develop  when hydrochloric acid comes  in contact with iron or copper.  ASME Boiler And Pressure Vessel Code  ASME has published Code  Case 2140 for solution annealed HASTELLOY B-3 alloy  (UNS N10675).  The alloy is  also covered by ASTM specifications B333 (plate, sheet and  strip), B335 (bar), B366  (welded fittings), B564  (forgings), B619 (welded pipe),  B622 (seamless pipe and  tube) and B626 (welded tube).  Nominal Chemical Composition, Weight Percent  Ni Mo Cr Fe Co W Mn Al Ti Si C  65  b  28.5 1.5 1.5 3* 3* 3* 0.5* 0.2* 0.1* 0.01*  held at 2250°F (1230°C) for a  time sufficient to bring the  entire piece to temperature.  Since it is a low carbon alloy,  the use of lower hot finishing  temperatures may be necessary to achieve grain size  control.  B-3 alloy may also be formed  by cold working.  Although it  does work-harden somewhat  rapidly, B-3 alloy components  can be made using all common cold forming techniques.  Limited tests in boiling 20  percent hydrochloric acid  indicate that the uniform  corrosion resistance of B-3  alloy is not affected by cold  reductions up to 50 percent as  compared to that of the alloy in  the solution heat-treated  condition.  B-3 alloy can be welded by all  common welding techniques,  although oxyacetylene and  submerged arc welding  processes are not recommended when the fabricated  item is to be used in corrosive  service.  Special precautions  should be taken to avoid  excessive heat input.  Heat Treatment  All wrought forms of  HASTELLOY B-3 alloy are  furnished in the solution heattreated condition unless  otherwise specified.  B-3 alloy  is solution heat-treated at
