Can air fires melt steel?

Question

FACT 1: Melting point of iron (steel) : 1532 C.

FACT 2: Burning temperature of hydrocarbon fuels in air: 250 C

FACT 3: At 250 C, steel does not lose any of its strength. At
600 C, steel is around 50% of its maximum room temperature
strength, but these temperatures cannot be reached by air
fires simply because there is not enough oxygen in 101.3 kPa
or 1 atmosphere normal air pressure. (oxygen makes up only
about 19% of the air we breathe, inert gas nitrogen 80%)

FACT 4: Most of us drive in cars that use internal combustion
engines which contain high pressure explosions and raging
hot fires; even the pistons are made of iron. The same
kind of material used for barbeque grills! We all use steel
cooking pots and frying pans, constantly exposed to gas stove
fires, to cook our food every day. What about steam engine
boilers exposed to fires! Do they fail?

Answer 1

I don't think people understand how weak the offical story is.

Answer 2

alright, #1 your facts are wrong. Where did you get them? Hydrocarbon fuels can burn at temperatures up to 1600C. Even paper fires are about 800C. If the fire appears red, then its at least 800C. If is yellow its probably 1200C and if its white is 1600C or greater. Color of fire can be a good indicator of temperature. Heres how steel gives way under moderate fire temperatures. Lets just say that the fire from that jet fuel was hot, but not really hot for a hydrocarbon fuel, say 800-1000C. Definitely not enough to melt steel (some steels melt as low as 1148C, but we dont need to go there to explain this). Okay so now we consider what happens to steel at 800-1000C. The structure of steel is hard and strong because it has many deformations, sort of like tiny cracks and bends in the metal structure. These are put in place intentionally during heat treatments and/or cold working. When metals are heated up, the structure has more ability to move around and it resettles into a aligned crystal structure. The structure is not as rigid. In fact most steels less than 1.5% carbon will actually change structure back to gamma iron (austenite). Austenite at this teperature is soft and bends easily. This is why blacksmiths heat steel swords before they smash them. They are soft and more easily change shape. Now if you knew anything about material sciences before you asked the question you would have known that jet fuel would easily soften the steel. And considering the tons of concrete it was holding, the instant once bar began to bend because of lost strength, all of them would have because more and more weight would have been applied to each.

Answer 3

I know what you're trying to get at here, but no dice. It has to do with the amount of oxygen as well. A regular fire won't get hot enough to melt iron. But if you point an ordinary pair of bellows at the flame and start pumping, voila! More air/oxygen equals more heat. You ever visit an old blacksmith's shop? They melt iron with a coal fire and leather bellows. Automobile engine is a bad example. I've melted steel piston heads because of the wrong air/fuel mixture. In the 9-11 scenerio, you've left out another important fuel source. The aluminum of the airplanes. Aluminum will burn real hot. It contains magnesium. Pure magnesium will ignite in open air. All by itself. That's what they make incendiary bombs out of. See the WWII firebombings of Dresden and Tokyo. But at 9-11 it had a lot to do with the vortex of air rushing into the fire. All that steel just started melting and moving in one big glob, down. Anyway, you don't have to totally melt the structure, just weaken the support beams and the whole mess collapses inward. Folds in on itself. Down she comes. Like a house of cards.

Answer 4

Cars have cooling systems and the engine blocks crack or blow a gasket if they fail, so it can't reach that point. Furnaces have safety switches so as not to exceed specified temps, and the furnace shuts down if the sensor fails. The water in a boiler absorbs heat from the boiler itself and also has safeties. I've seen powdered metal start burning just from a careless cigarette, and "back when" railroads would weld cracked rail with a portable mold with powdered iron and a little powdered aluminum. They would ignite the aluminum powder which would then burn hot enough to ignite the iron powder. It was called Thermite welding.

Answer 5

So how did the soldiers in the American civil war use plain old bonfires made of wood to bend railroad ties? We know they did it. There are lots of pictures. Or did the Republicans go back and plant that in our history to fool us! The support beams did not have to melt away just soften enough to bend. Easy to do. Pistons are protected by the oil inside the engine. Take away the lubricant and watch how fast it burns. Have you ever worked on a car that was destroyed by fire and seen the melted metal? Guess not.. And your BBQ grill isn't supporting anything heavier than a burger and it is not that hot as it constantly exposed to cool air

Answer 6

Of course boilers fail. They explode all the time. People used to be afraid of steam boilers because they exploded so much. Also, since you are going there, heat will distort metal at lower temps than the melting point.

Answer 7

how about the old forge fires in a blacksmith shop,they are just burning coals fanned with airand have formed, shaped and made many a sword wagon wheel and horseshoeand if not watched carefully will melt the product right away. fact: its not the temperature but the duration and concentration.

Answer 8

Now add plain fuel to the equation. And whatever other stuff that was present and that burns.

Oh, and the government agents are coming to pick you up for daring to question the truth.

Paranoid people make me tired. Go wear a tinfoil facemask, and leave out the airholes.

Answer 9

look, clearly the terrorists had learned to harness the power of the sun, jeez, isnt it obvious! people are sheep, and thats just what the elites think of you as they laugh to the bank and onward toward their goal of global government and a police state in america. Kissinger once referred pointedly to military men as "dumb, stupid animals to be used" as pawns for foreign policy.

Answer 10

It was an inside job and all about numbers, dates, and the occult!...
