What temperature melts steel? Confidence votes 25. Steel often melts at around 1370 degrees C (2500 °F). This varies depending on the specific steel alloy. The specific heat of steel varied from 420J/KG/Deg C at room temperature to 720J/KG/Deg C at 1535 deg C. This equates to a theoretical heat requirement of approximately 375KWh/mt to melt steel from room temperature. In practice, foundries use between 500 and 800 KWh /mt to raise steel to a little above its melting point of 1535deg C.

How hot can you get a coal fired forge? How hot can you get a coal fired forge? According to Marks' Standard Handbook for Mechanical Engineers, 10th, coal gas burns at about 3,590°F (1,977°C) under 100% air conditions. More or less air will decrease the temperature. This means that the maximum temperature of a coal fire in a forge is about 3,500°F (1,927°C). Most organic compounds have a constant-pressure adiabatic flame temperature in a narrow range around 1950 °C.

Steel-Melting Fires FACT: Jet fuel burns at 800º to 1500ºF, not hot enough to melt steel (2750ºF). However, experts agree that for the towers to collapse, their steel frames didn't need to melt, they just had to lose some of their structural strength--and that required exposure to much less heat.

How Much Wattage do I Need? To calculate the wattage requirement to heat steel, use the following equation: Watts = 0.05 x Lbs of Steel x δT (in °F) / Heat-Up Time (in hrs) Example: To heat 50 lbs of steel by 250°F in 1 hour; .05 x 50 x 250 / 1 = 625 Watts. Using the same example, reaching temperature in 15 minutes (0.25 hrs); .05 x 50 x 250 / .25 = 2,500 Watts. This equation is suitable for mild and stainless steels.

- In a controlled burn (where oxygen and fuel are regulated in an optimal mix), jet fuel will reach a maximum temperature of 1800F(982C), which is still not anywhere near the temperature required to weaken the steel girders of a building to the point that the entire building plummeted to the ground.he actual maximum burning temperature of a Jet-A fuel (standard jet fuel type in U.S.) is 980 deg. Celsius. If you refer to the Iron-Iron Carbide phase diagram, the temperature at which steel changes from cementite and pearlite (strong phases of steel) to austenite (significantly less strong) is 702.5 deg.

How to Melt Brass Ilya Stcherbakov/iStock/Getty Images. 1,688 degrees Fahrenheit is an extremely hot temperature; however, in metallurgy it is considered a low melting point. Compared to iron's melting point -- 2,786 degrees Fahrenheit -- the average melting point of brass at 1,688 makes it a low-melting alloy.

How Hot Does A Lighter Need to Get to Melt Glass? So how hot does it really need to be in order to do this, and what type of lighter would you have to use? The average melting point of glass is somewhere around 1500 degrees Celsius. This is certainly hotter than most lighters get, and it would take quite a bit of time to heat the glass to this point. If you are looking to melt glass, however, you will find that you have to choose lighters that can offer a sustained flame that burns at a very high temperature.

Property Information 1 The strength of a material tends to fall quickly when a certain temperature is reached. 2  This temperature limits the maximum operating temperature for which the material is useful. 3  For metals the maximum operating temperature is usually around two thirds of the melting temperature. For prolonged loading the maximum stress will be lower because creep (permanent stretching over time) will occur. 2  The data for a material on the selection chart shows the range in which the maximum service temperature fall (since a given material on the chart will include many different variants with the same name).

- Construction grade steel burns at 2795 degrees Fahrenheit. Jet fuel  does not burn this hot. Its maximum temperature is 1472 degrees  Fahrenheit.hen the air is colder (it easily gets -40  degrees up there) and the fuel air mixture is burned, the air  expands alot more than if warm air was entering the engine. On a  warm day a jet will not perform nearly as well as on a cold  day.

- In addition to WhatRoughBeast's excellent answer let me also debunk the 'Thermite myth' that's so pervasive in 9/11 conspiratorial thinking. This misconception that burning Thermite could cause steel beams to melt is based on a poor comprehension of Heat Transfer. Adherents of the Thermite thesis start from the correct knowledge that burning Thermite mixtures can reach temperatures in excess of 2,500 centigrade, well above the melting point of steel.
