Pyrocast M70 is a metallic fiber-reinforced precast refractory shape. Its unique design allows addition of metallic reinforcing fibers at levels significantly above those used in traditionally designed refractory castables. The finished shapes have enhanced mechanical toughness and surface finish. Pyrocast M70 shapes have excellent hot strength, thermal shock resistance, and abrasion resistance in all directions due to random fiber distribution and alignment. It can withstand a wide variety of very destructive high temperature environments and is sold as preformed, prefired shapes.
