· The stainless steel fibers serve to reinforce the refractory section and bridge the crack which gives the lining greater stability and integrity. Stainless steel fibers become ineffective above 1500 °F (815 °C) because of oxidation. Once the fibers oxidize, they are no longer effective in providing stability.
