904-grade Duraflue has a 30-year guarantee. 316-grade has a 15-year guarantee

A flue liner is not a product you want to fail within just a few years. Silvacore is manufactured by Duraflue and is designed for professional trade-fitters desiring a premium product for chimney lining. 904 Silvacore has a 30-year guarantee against failure via corrosion. 316 Silvacore has a 15-year guarantee against failure via corrosion.
Duraflue is created from two compressed stainless steel layers, the this unique laminate stays smooth when the product is passed around chimney bends (with lesser quality liner the laminate usually comes apart allowing acids from soot deposits to enter and cause corrosion).
904 and 316 are grades of stainless steel. If you are a heavy user of coal/smokeless fuel then one would be advised to choose 904 grade. As is the norm with chimney-liner manufacturers, chimney liner CANNOT be returned as this is a customised cut-to-length item direct from manufacturer on your behalf. Liner can be cut with a hacksaw. Silvacore can be fitted any way up in chimney.
Duraflue were a finalist at The Hearth and home Show 2013 > Product of the Year.

Silvacore "904" liner is 904 grade stainless steel internal, with an extra 316 external layer as additional protection against moisture
