Mild Steel Temp Limit?
Mild Steel Temp Limit?
(OP)
I'm a glass artist working on a new project. I'm planning to wrap/thread molten glass around a rotating steel frame. I'm wondering how much heat the steel (common black plumbing pipe) can withstand before "fire scaling" will become a problem. I plan to coat the frame with a graphite spray to act as a release, perhaps it will also protect from the oxidation too? I think 1200f will be hot enough for the process. I'll be firing with propane.
Any ideas or advice will be appreciated.

RE: Mild Steel Temp Limit?
As for the flaking, almost any repetitive temperature above a few hundred degrees will cause enhanced surface corrosion. Your best bet is to clean and coat each time.
Another possibility is to ceramic coat the steel or use a ceramic rod in place of the steel.

I'd planned on coating the steel with a graphite mold coating. Maybe that will help? I'll sand blast the form and recoat before each firing. If that doesn't work I guess I'll switch to stainless.

I just started using the black plumbing pipe because it was readily available and cheap. What are the names/numbers for some common heat resistant alloys?
Thanks,
