In most high-temperature industrial applications, the operating environment is such that carbon or low-alloy steels offer sufficient resistance to oxidation. Often, it is not the lack of high-temperature corrosion resistance that restricts the use of carbon and low alloy steels in high-temperature oxidizing environments, but the loss of strength at temperatures of 650 C (1,200 F) and higher. As a result, Cr-Ni-Mo steels, which can contain 12 to 25% nickel, are frequently specified for use up to 1,150 C (2,100 F). These steels offer improved high-temperature strength because of their austenitic structure and higher nickel content. Additionally, they do not lose toughness after prolonged exposure to intermediate temperatures, as do ferritic Cr-Mo steels having more than 12% chromium. This characteristic is often referred to as 855F (475C) embrittlement.'
