    AISI 446 UNS S44600 Stainless Steel Seamless Tube / Thermocouple Protection Tube

    AISI 446 UNS S44600 Stainless Steel Seamless Tube / Thermocouple protection tube


    S44600 is a ferritic, stainless chromium steel for use in high-temperature applications such as

    recuperators in the metallurgical and glass industries and thermocouple protection tubes.


    The stainless AISI 446 grade is especially suitable for sulfurous flue gas atmospheres and can be used

    at temperatures up to 1100°C (2010°F), depending on the service parameters and application.

    The ferritic structure of 446 stainless also gives it good resistance to extremely corrosive metal melts,

    such as copper, tin and lead.


    Extremely good resistance to reducing sulphurous gases
    The grade's extremely good resistance to reducing sulfudizing gases and salts, compared with austenitic stainless steels,

    is due to the high chromium content and absence of nickel.

    446 stainless also exhibits excellent resistance to isothermal and cyclic oxidation in air.


    Main characteristics of 446 stainless steel seamless tubes

    • Extremely good resistance to reducing sulfurous combustion gases
    • Very good resistance to oxidation in air
    • Good resistance to oil-ash corrosion
    • Good resistance to molten copper, lead and tin

    Typical applications for high temperature ferritic grade 446 stainless are:

    • Recuperators in the metallurgical and glass industries
    • Thermocouple protection tubes
    • Sootblower tubes
    • Injection nozzles
    • Muffle tubes in continous wire annealing furnaces
