Ferritic SS 446
ALLOY 446 | 1.4763 | S44600
Ferritic SS 446 has the best corrosion resistance among all the grades in 400 series, notably due to its high chromium content (26%). It is commonly used in applications having a high-temperature range about 1500°F to 2100°F because it has exceptional high-temperature resistance to oxidation and corrosion.
The strength of the metal might decrease a little at elevated temperatures but finds its place due to its resistance to oxidation in air, and resistance to various other media at elevated temperatures.
The alloy can also suitably resist cyclic oxidation. The grade has superior scaling resistance than the majority of 400 and 300 series alloys.
