• Stainless steel wool is made from Alloy type AISI 434 stainless steel.
• The 5 lb reels are a web of stainless steel wool approximately 1/4" thick by 4" wide, 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.
• CHEMISTRY : C (Carbon) 0.12% max. ; Si (Silicon) 1.0% max. ; Mn (Manganese) 1.0% max. ; S (Sulfur) 0.03% max. ;P (Phosphorous) 0.04% max. ; Cr (Chromium) 16.0 - 18.0% max. ; Mo (Molybdenum) 1.25% max.; Fe (Iron) remainder
• 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.

I do need to disagree on a small degree...the gauge of steel wool you used wont burn, but most likely the guys argueing with you are using more like 0000 steel wool...which will burn extremely easily with just a spark or lighter...have set it on fire many times to watch the fire worms run...fun...your tip is good and will most likely be great for me as I need to pack mine today and will try to heavy gauge wool...thanks for the tip.

They wrapped what looks like fiberglass around a central core of steel wool.Yes you have to have the right thickness steel wool . See the specs of the product I posted.

I received the roll of SS Steel Wool

I took a small strand and held in a direct gas stove flame until it was bright red and left it for abouut 1 minute. It did not burn away. It was not shiney anymore but that is about it. This is much worse than any exhaust can. Should be fine for packing exhaust cans.

I'm still waiting on a baffle to rebuild my Muzzy

Now HERE'S where it gets fun.....how to repack your exhaust when the PO removed the baffle and you have nothing to wrap the steel wool around! Any ideas on fabricating a baffle?

if it for your ironhead , ive got a set of oem pipes with cross tube on an 82 xlh 1000 i got about 2 weeks ago . if its for ricer ive used soup can with holes drilled in it with a 1 3/4 harley baffle screwed to inside of can wrapped in steel wool . laugh if you want but it worked for a year until the screw holding it in came out and it shot out on hwy .
