Any steel that gets red hot is doomed, it just takes time. The hotter it gets the less time it takes. If it's insulated, it just gets hotter quicker.
Growing up, we had a 100 year old wood stove. The cast parts cracked. The steel parts that got red warped and developed pinholes amd then bigger holes and had to be welded and patched.
The stove is still sitting at my dad's place. I think it may be up to 150 years old now. I should get pictures for discussions like this.

Sure it's in a rough shape but it's more than a century old. I assume it's not a rocket type stove but still. I'd like to see it though, would be interesting! I'm not a metal expert but I think what I used is what Americans call "mild steel", I assume that's a general and most common type used. It rusts pretty easily and is malleable. Anyway, the heat riser is 4mm thick and the body is also from 4mm thick steel of the same type. The feed tube is only 1.5mm but it doesn't get all that hot, only at the bottom. I'd really like to know how hot different parts of the stove get, I don't have anything to measure that kind of temperatures so I'll have to get something. But based of what I said about my stove so far, how long any of you reckon will it last, assuming it would burn at least 8hrs/day? |

You're not listening. I'm out.

But based of what I said about my stove so far, how long any of you reckon will it last, assuming it would burn at least 8hrs/day? Solomon gives a good example of how you can kill an old fashion wood stove if you run them to hot. I remember my grandpa would watch the chimney temp very closely, he use to get these 2x4 end cuts to burn. That kiln dried pine lumber burns quick and hot. Its not hard to overheat a wood stove if you really want to You can use steel in a wood heater, just know that if its "Inside" the heater or "insulated" in a hot part of the heater it will reduce its life. Its great for the flue/chimney since temps are lower. You can make the whole thing out of steel and it will survive fine because steel radiates heat pretty well. Problem is, it radiates heat to fast so you don't get the higher burn temps as you do with the ceramic fiber or masonry heaters. You have to have an insulated(no bare steel) burn chambers if you want to have a cleaner burn. When you add steel to hot parts of more insulated wood stoves, it doesn't last very long. So build it as a consumable and just replace it when needed. |
