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, where the excellent resistance of the material to slag corrosion and sulphdizing gas is very obviuos.
