Alloy 601 / 2.4851

Alloy 601H is a nickel-chromium-iron alloy with additions of aluminium and titanium. It is characterized by:

- outstanding resistance to oxidation at high temperatures

- good resistance to carburizing conditions

- good resistance to stress-corrosion cracking

- good resistance at oxidating, sulfur-containing atmospheres good mechanical properties at both room and elevated temperatures due to solid solution hardening

Main fields of application of alloy 601H

In the sector of elevated temperatures, Alloy601H has a wide variety of applications. Apart from applications in furnace construction, chemical processing, pollution control and power generation, there is a variety of further purposes, i.e.:

- refractory anchors, strand-annealing and radiant heater tubes, high-velocity gas burners, wire mesh belts in industrial furnaces

- trays, baskets and fixtures for heat treatment plant , i.e. for carbonization or carbonitiding

- combustion chambers in solid waste incinerators

- components in exhaust gas systems

- tube supports and ash-handling components
