White cast iron has a high resistance to corrosion and abrasion, making it useful for:

White cast iron is particularly valued for its high resistance to corrosion and abrasion, which makes it suitable for applications where wear and tear from particles is a concern. In ash handling systems, materials often encounter abrasive conditions due to the harsh nature of solid ash residues. The durability of white cast iron allows it to withstand these conditions, reducing wear and extending service life.

In contrast, while condensate lines, natural gas supply lines, and underground steam lines have specific material requirements based on pressure, temperature, and chemical compatibility, they do not benefit as significantly from the unique properties of white cast iron. For instance, condensate lines primarily require materials that are airtight and corrosion-resistant at specific temperature levels, and gas lines must safely manage gas under pressure and have to consider factors like flammability. Underground steam lines need to handle high pressure and temperature, often requiring specific alloys.

Thus, the use of white cast iron is most aligned with applications like ash handling systems, where its abrasion resistance is paramount.
