Nitric acid catalyst grids

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.

turbine engine combustor

Textron Lycoming gas turbine engine combustor made of HAYNES® 230® alloy.

230® combustor for Dresser-Rand DR-990 land-based turbine

Prototype 230® combustor for Dresser-Rand DR-990 industrial turbine.

Resistance-heated 230 superheater tubes

Resistance-heated 230® superheater tubes at the Penn State Applied Research Laboratory.  Used to produce about 1625°F (885°C) high-pressure steam. 

high-temperature expansion bellows

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

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)

Fabricated heat-treating basket for vacuum furnace application to 2300°F (1260°C). Made from 1/2-inch (12.7 mm) diameter 230® bar.

HAYNES 230 heat-treat fixture

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).

damper atop glass melting furnace

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

Cast heat-treat basket of 230® alloy in use at Alloy Foundries, Division of the Eastern Company, Naugatuck, Connecticut.

Substrate holder and box

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)

230® retorts operate at 2100°F (1150°C) with a hydrogen atmosphere (inside) and combustion products outside.
