TP446-1 is a heat-resistance ferritic chromium-alloy stainless steel. It just has very little nickel content and has the following characteristic:

-Material could be used at high temperature up to 1100 grade

-Very good resistance to oxidation in air

-Excellent resistance to reducing sulphurous gas

-Good resistance to oil-ash corrosion

-Good resistance to molten copper, lead and tin

 

TP446-1 is the ferritic chromium-alloy material. It has the excellent heat-resistance capability and mainly served at temperature above 700 grade, where the excellent resistance of the material to slag corrosion and sulphdizing gas is very obvious.

 

The typical applications include the following:

 

Tube used in the recuperator in the metallurgical and glass industry

Tube used as the thermocouple protection tube

Tube used as the soot blower tube

Tube used as the high temperature injection nozzle

Tube used as the furnace tube in the wire industry
