TYPICAL APPLICATIONS

Nitric acid catalyst grids support made from 
HAYNES® 230® alloy plate and bar. 
Excellent creep strength at 1700°F (927°C) 
makes the alloy highly suitable for this application.
Textron Lycoming gas turbine engine combustor made of HAYNES® 230® alloy.
Prototype 230® combustor for Dresser-Rand DR-990 land-based turbine. 
Resistance-heated 230 superheater tubes at the Penn State Applied Research Laboratory.  Used to produce about 1625°F (885°C) high-pressure steam. 
Prototype 230 high-temperature expansion bellows made of 0.020-inch (0.5mm) thick sheet in a catalytic cracker configuration. 
This horizontal electrically fired 230® retort replaced an alloy 600 retort which lasted only an average of  eight months in 1400 to 2200°F (760 to 1205°C) service in hydrogen atmosphere.  The 230 retort was still in excellent condition after 24 months service, as shown.
Wire annealing fixture of 230 alloy reduces thermal mass and cycle times after replacing massive carbon-steel "stub" used previously. 
Fabricated heat-treating basket for vacuum furnace application to 2300°F (1260°C).  Made from 1/2-inch (12.7 mm) diameter 230 bar. 
This striking shot of a HAYNES 230 heat-treat fixture was taken at a leading off-road automotive equipment plant.  This conveyor fixture operates at 1550°F (845°C) with a subsequent water quench followed by a four hour cycle at 1050°F (565°C).
HAYNES® 230® damper atop this glass melting furnace withstands 2300°F (1260°C) for short times and 2000°F (1095°C) for sustained periods.
Cast heat-treat basket of 230 alloy in use at Alloy Foundries, Division of the Eastern Company, Naugatuck, Connecticut.
Substrate holder and box  of 230 alloy resist temperatures of 1650°F (900°C) during the production of semiconductors.
230 retorts operate at 2100°F (1150°C) with a hydrogen atmosphere (inside) and combustion products outside.
