446, S44600, SAE 51446 CHROMIUM HEAT RESISTING STAINLESS STEEL
Description
446 is a non-hardenable chromium steel which has the highest corrosion and heat resisting properties of the straight chromium steels. This grade is magnetic at all times.
The excellent corrosion resistance of this non-hardenable, ferritic stainless is due to the high chromium content. This allows use in applications such as heaters, burners, nozzles, electrodes, and metal-ceramic seals. Typical annealing temperatures are 730-815°C; followed by air or water quench.
Applications
Neutral salt pot electrodes, Recuperators, Spouts for conveying molten copper alloys, Oil burner parts, Combustion chambers, Furnace and kiln linings, Stack dampers, Boiler baffles, Glass molds, Soot blowers
