Ni-Chrome Super Alloy Castings

Castings we make

Castings for where ordinary steel gives up

Reformers, fired heaters, kilns, crushers and reactors destroy plain steel three ways: heat, corrosion and wear. We cast the parts that hold up, plus the general steel castings around them, to your grade and standard. Here is the full range. Send a drawing for anything not shown.

Heat

Fired heaters and reformers run at 900 to 1,100 °C, where ordinary steel creeps and scales. Our heat-resistant grades hold their shape and strength.

HK40 · HH · HP-Nb · HF

Corrosion

Fuel ash and process gases eat into hot metal. High chromium-nickel grades resist the attack at temperature, in refinery and petrochemical service.

50Cr-50Ni-Nb · HN · SS316

Wear

Coal, clinker and ore grind steel away. Ni-hard, high-chrome and manganese grades take the abrasion at 400 BHN and above, and keep their edge.
