high heat effects
(OP)
Can someone give me an idea or reference for infomation on the effects of high heat on A36 steel properties. What happens to Fy and E at temperatures around 1500 deg C (2730 deg F)
THANKS

No mechanical properties to speak of.

RE: high heat effects
The steel in question is part of a burner lance in a cement kiln...1500 deg C. The lance is encased in a refractery, but I was curious what effects temperature has on the steel alone. I suppose it is not a valid question, the refractery must be there or the steel will melt.
Forgeting the high temperature of the kiln, is there a rule of what happens to yield stress and modulus at high temeratures?
RE: high heat effects
I think its MIL-HDBK-5J that has the graphs of modulus vs temp.
RE: high heat effects
You'd expect this w/alum. alloys but it happens with steel too.
RE: high heat effects
When I was in the steel making business, A-36 was next to the bottom of the barrel; only steel "lower" being continuous butt welded "Fence Post". A-36 was a dumping ground for high strength materials that didn't meet chemical requirements. The permitted chemistry variations and melting practices of A-36 gaurantee substantive changes in mechanical properties with temperature from heat to heat.
