MAPP gas, which is a combination of propane and methylacetylene-propadiene, burns somewhat hotter than pure propane. The gas in these yellow cylinders burns at a temperature of 3,720 degrees Fahrenheit (2,050 degrees Celsius). Torches built for high-temperature work combine MAP gas with pure oxygen, allowing for complete combustion that would otherwise be impossible in ambient air. The highest temperature of these torches is 5,200 degrees F (2,870 degrees C), which is hot enough to melt iron or steel.
With a propane torch, how hot can you get steel?
Because a propane torch can only reach a particular maximum temperature, melting metal will take much longer than most other projects. Most metals have a melting point of roughly 1,800 degrees, while a propane torch has a maximum heat point of around 1,900 degrees.
What is the maximum temperature that propane torches can reach?
The highest temperature of an air-fed torch is roughly 2,000 C. (3,600 F). A typical primary flame, on the other hand, will only reach temperatures of 1,100 C (2,000 F) to 1,250 C. (2,250 F). Oxygen-fueled torches may reach temperatures of up to 2,550 degrees Celsius (4,600 F).
Is it possible to melt a weld using a propane torch?
How do you use a propane torch to weld? Although a propane torch is easier to use than a butane flame, it is still only appropriate for specific types of braze welding, such as silver soldering or brass brazing.
A propane torch does not reach high enough temperatures to allow for fusion welding.
Note: Do not use a butane lighter to fire a propane blowtorch. Because compressed propane is extremely combustible, a flashback could result in an explosion.

What is the maximum temperature a butane torch can reach before it melts metal?
A butane torch is a gadget that uses butane, a combustible gas that is decreased in ambient air, to create an exceedingly hot flame.
Consumer air butane torches are frequently advertised as having flame temperatures of up to 1,430 degrees Celsius (2,610 F). Many common metals, such as aluminum and copper, melt at this temperature, and many organic molecules evaporate at the same time.
Is it possible to cut steel with a propane torch?
When it comes to cutting steel, there are various methods available, but in this post, I’d want to focus on oxy-fuel gas cutting, specifically a method that uses propane gas as a fuel.
There are numerous advantages to utilizing propane gas instead of acetylene, but there are also some drawbacks.
Propane is a considerably less expensive gas to purchase, transport, and store, and it is much safer to use, transport, and store.
There are however certain distinctions that expert operators might take advantage of. Propane, for example, burns at lower temperatures than acetylene, making it suitable for gas welding or braising of very thin metals or meshes. When it comes to cutting steel with propane gas, the most important advantages are safety and cost. Propane is a little more difficult to use because of the lower burning temperature, and it’s especially difficult to light and maintain a flame going outside in the wind.
We must be aware of one very specific phenomenon in order to comprehend the gas cutting process.
Steel can burn at a temperature lower than its melting temperature in a pure oxygen atmosphere. You can see a red glow of wood as it being burned without a flame if you take up a hot smoldered piece of wood and blow at it. It’s similar to what happens to steel in a completely oxygen-free atmosphere. The heating flame serves only to bring the steel to kindling temperature, after which the jet of pure cutting oxygen burns away that small area of steel. The concentrated jet of pure cutting oxygen not only burns and oxidizes the steel in the cut line, but it also clears any oxidation products from the cut gap, preventing them from fusing to the freshly cut sides. A jet, fountain, or stream of molten metal can be seen under the material we’re cutting.
Stainless steel can also be cut with gas cutting equipment, but it necessitates the application of a particular flux on a continuous basis during the cutting operation. Because of the physical features of oxides and their high thermal resistivity, this occurs. Because oxides melt at higher temperatures than parent materials, a flux that can break down those oxides is required. Naturally, with technological advancements, oxy-fuel cutting of stainless steel in a manufacturing environment is a rare sight. Wherever possible, more effective procedures such as plasma cutting or abrasive cutting have mostly replaced this sort of gas cutting.
Let’s take a look at the structure of a gas cutting flame, what we can learn from it, and how we may tailor the flame to our needs.
Here is a collection of photographs that depict various sorts of flames. The first is a standard flame, in which
What is the temperature of a Bernzomatic butane torch?
The Bernzomatic Butane Refill 5.6 oz cylinder is designed to refill Bernzomatic micro torches, lighters, cordless soldering irons, and other butane-powered equipment quickly. It has a universal fueling tip that makes refilling a breeze. The in-air flame temperature of butane fuel is 3,150 degrees Fahrenheit.
Is it possible to braze using a propane torch?
Using a flame, brazing permanently connects two metals. Most metals can be brazed together using a propane torch. Propane torches are frequently accessible at local hardware stores, plumbing supply stores, and metalsmith and jewelry supply stores.
What is the maximum temperature of Bernzomatic gas?
The sturdy steel cylinder is compact and light, making it easy to grip and maneuver. This item can be used in conjunction with our Digital Fuel Gauge to simply determine how much fuel is left in the cylinder. The in-air flame temperature of MAP-Pro fuel is 3,730 degrees Fahrenheit.
Is it possible to weld using a Bernzomatic?
When inverted, it includes a sturdy brass burn wand, independent fuel and oxygen controls, and is pressure regulated for constant performance, making it perfect for small brazing, welding, and metal-cutting operations.
