  • Stainless steel wool is made from Alloy type AISI 434 stainless steel.
  • A web of metal wool approximately 1/4″ thick by 4″ wide is wound onto a 2-3/8″ ID fiber core to an outside diameter of about 8-12″ and weighing exactly 5 pounds net.All products are about 125 feet of web per 5-pound reel.
  • Stainless steel wool products withstand temperatures in excess of 700°C, exhaust acids and high vibration.
  • Furnace tests show that stainless steel wool will withstand sustained temperatures of 700°C and peak temperatures of 800° C for up to 10 minutes without damage or degradation.

  • Common Reels: The simplest form of stainless steel wool is a continuous roving, 4 inches wide on reels. This product meets all of the physical demands for exhaust applications, but is presented in a basic form requiring the muffler manufacturer to do all of the processing and assembly.
