253MA Heat Resistant SS Tube 25mm 38mm 1150°C Oxidation Resistant Radiant Furnace Tube
Product Spotlights
Product Description:
This 253MA heat resistant stainless steel tube is available in 25mm and 38mm outside diameters, designed for continuous service at temperatures up to 1150°C. The rare earth element (cerium) addition promotes superior oxide scale adhesion and spalling resistance during thermal cycling. The alloy also offers excellent resistance to carburization, sulfidation, and oxidation. Typical applications include radiant tubes in industrial furnaces, furnace roller hearth tubes, kiln components, ceramic kiln furniture supports, heat treatment furnace muffles, incinerator heat exchanger tubes, petrochemical cracking furnace tubes, and high-temperature convection section tubes.
