High Temperature Carbon Steel

For a prolonged service life, such as 20 years, plain carbon steels are usually limited to a maximum operating temperature of 750°F (399°C); the ½% molybdenum alloy steels to approximately 850°F (454°C); and the stainless steels to considerably higher temperatures depending upon the type used.
