Aluminized Steel Tube SA1D-80 is a steel tubed grade with high temperature oxidation resistance, structural strength and good formability. It is made from low carbon steel and has an aluminium/silicon coating for good heat reflectivity and protection in challenging thermal conditions. SA1D-80 is a designation that is used to indicate the type 1 aluminum-silicon coating, forming-grade substrate and coating weight of AS80. The tubes are often used in automotive exhaust, muffler, heat shields, industrial furnaces, and ovens where they are subjected to high temperatures. SA1D-80 tubing is available in various sizes and specifications, which can be used for different types of fabrication processes, including bending and forming. Amardeep Steel Centre is an aluminized steel tube SA1D-80 manufacturer and supplier.
