Constructed with two layers of stainless steel, available in 316/316 and 904/904 grade, these chimney liners increase the efficiency of the chimney to extract combustion gases and carbon monoxide from your stove, fireplace, or appliance.
Distinguishing between 316 and 904 flue liners lies in the composition of their stainless-steel layers. Stainless steel, a blend of iron ore, silicon, nickel, chromium, molybdenum, and carbon, yields a corrosion-resistant steel variant. Varying the exact proportions of these elements alters the steel's properties, influencing factors like corrosion resistance, hardness, and malleability, resulting in different grades.
The 904 grade boasts enhanced resistance to corrosive chemicals compared to the 316 grade, particularly with acidic residues from fuel combustion
