(The local oliver dealer was a friend of my dad's in town and, very young, I remember gawking at them while they talked. One of those very pleasant bit memories. We were always 'oliver people'. There were lots of Oliver and F-A and only some green around here, then.)
Not sure if it's 304 or 316. I was looking to buy metal chimney with 316 (or better)stainless. Went to Amish man who sells metal chimneys. His neighbor sells the coal stoves. He didn't know what grade stainless pipe he sold. We looked on boxes , literature , on the pipe itself , etc.. Couldn't find any info. Amish man claims lots of people buy that pipe from him , and no problems. So , I took my chances. I haven't had any problems with the chimney , other than some very minor surface rust from the top - down about 12 inches. The cheap chimney cap corroded apart , allowing water to enter the chimney. The chimney was 6 years old when I noticed the cap was shot. That's when I noticed the surface rust near the top of chimney. The chimney has many good years left in it , as long as I maintain it. Would I put another metal chimney in??? Most likely. Only due to ease of installation. Next time I'll verify the quality of stainless. I would still recommend masonary chimney over metal.
