Applications
ALLOY601 has found a wide variety of applications in industries as diverse as thermal and chemical processing, pollution control and power generation.
Typical applications are
• trays, baskets and fixtures for heat treatment plant
• refractory anchors, strand-annealing and radiant heater tubes, high-velocity gas burners, wire mesh belts in industrial furnaces
• insulating cans in ammonia reformers and catalyst support grids in nitric acid production
• components in exhaust gas systems
• combustion chambers in solid waste incinerators
• tube supports and ash-handling components
• components of waste-gas detoxification systems
• oxygen preheaters
- Containment rings in gas turbines
- Air preheaters
- Catalyst regenerators
- Combustion chambers in solidwaste incinerators
- Thermal reactors in exhaust systems of gasoline engines
- Trays for annealing / carburizing / carbonitriding / nitriding
Material Summary
ALLOY601 is a solid solution strengthened Ni-Cr-Fe alloy with additions of Al + Ti
• outstanding resistance to oxidation at high temperatures
• good resistance to carburizing conditions
• good mechanical properties at both room and elevated temperatures
• good resistance to stress-corrosion cracking
Alloy 601 is specifically recommended for service above 550 °C (1022 °F) because of higher creep-rupture properties, resulting from controlled carbon content and coarse grain size.
