What Temperature Will MAPP Gas Reach?

The in-air flame temperature of MAP-Pro fuel is 3,730 degrees Fahrenheit.

What is the maximum temperature that MAPP gas can reach?

Because of its high flame temperature of 2925 C (5300 F) in oxygen, genuine MAPP gas can be used in conjunction with oxygen for heating, soldering, brazing, and even welding. Although acetylene has a higher flame temperature (3160 C, 5720 F), MAPP has the advantage of requiring no dilution or special container fillers during transportation, allowing a larger amount of fuel gas to be transported at the same weight, and it is considerably safer in use.

Due to the high concentration of hydrogen in the flame higher than acetylene but lower than any of the other petroleum fuel gases a MAPP/oxygen flame is not totally suitable for welding steel. The hydrogen corrodes the welds by infusing itself into the molten steel. This is not a severe concern for small-scale MAPP welding because the hydrogen escapes rapidly, and MAPP/oxygen can be utilized to weld small steel pieces in practice.

Underwater cutting, which necessitates high gas pressures, MAPP/oxygen was shown to be beneficial (under such pressures acetylene can decompose explosively, making it dangerous to use). Underwater oxy/fuel gas cutting of any kind, on the other hand, has mostly been supplanted by exothermic cutting, which is faster and safer.

MAPP gas is also utilized in air combustion for brazing and soldering, where its higher combustion temperature of 2,020 C (3,670 F) in air gives it a modest edge over rival propane fuel.

The most significant disadvantage of MAPP gas is its high cost, which is typically one-and-a-half times that of propane at the refinery and up to four times that of propane at the consumer level. It is no longer widely utilized in any large-scale business; for bigger users, acetylene/oxygen is more cost-effective than MAPP/oxygen when high flame temperatures are required, and propane/air is more cost-effective when significant amounts of overall heating are required.

A MAPP/oxygen flame, on the other hand, is still extremely desired for small-scale users, as it has higher flame temperatures and energy densities than any other flame other than acetylene/oxygen, but without the hazards and hassles of acetylene/oxygen. It comes in handy for jewelers, glass bead makers, and a variety of other craftspeople. The high heat capacity of the MAPP/air flame is particularly valued by plumbers, refrigeration and HVAC experts, and other craftsmen; MAPP was frequently utilized until recently, and was provided in small to medium size containers.

Blowtorches are used to brown and sear food cooked sous-vide at low temperatures. MAPP gases should be used instead of cheaper butane or propane, according to Myhrvold’s Modernist cuisine: the art and science of cooking, since they create greater temperatures with less chance of giving the dish a gas flavor, which can occur with incompletely combusted gas.

MAPP gas vs propane: which is hotter?

Now that we’ve explored propane gas and MAPP gas individually, let’s compare the fuel types side by sidepropane vs MAPP gasbased on a few key factors:


It’s general knowledge that any form of gas, due to its extreme flammability, necessitates extra caution. In this case, one sort of gas poses a greater risk than the other. Extreme MAPP exposure, according to the National Institute for Occupational Safety and Health (NIOSH), is instantly harmful to life and health (IDLH).

Propane gas, on the other hand, is not harmful to human health. Because of its safety, even the United States Department of Agriculture promotes propane gas grills. Propane gas is the clear winner in terms of safety. Regardless, if you’re careful enough, you can utilize MAPP gas without issue.


Now let’s compare the temperatures of MAPP gas and propane; is MAPP gas hotter than propane? Yes is the correct response. MAPP gas has a maximum temperature of 3,730 F, whereas propane has a maximum temperature of 3,600 F.

What is the temperature at which a Bernzomatic burns?

The thin, lightweight cylinder is made of sturdy steel and is easy to grip and handle while working. This item can be used in conjunction with our Digital Fuel Gauge to simply determine how much fuel is left in the cylinder. The flame temperature of propane is 3,600 degrees Fahrenheit in the air.

What is the highest temperature at which MAPP gas can produce a flame?

MAPP has a maximum flame temperature of 2,929C (in oxygen). It has a strong main flame heat release (15,445kJ/m3), which is lower than Acetylene, comparable to Propylene, and higher than Propane (table 1).

Is it true that MAPP gas is hotter than acetylene?

They do, however, produce a significantly hotter flame. To many contractors and experts, the Mapp gas solution appears to be far superior at first appearance. The higher temperature of the oxygen-acetylene rig, on the other hand, is a critical element that should not be neglected.

Is it true that MAP gas is hotter than oxygen?

A torch that uses MAPP gas and oxygen produces a much hotter flame than one that only uses MAPP gas. It’s about or above 5000 F/2760 C, if I’m not mistaken. I tried but was unable to achieve this with the Bernzomatic MAPP alone torch. I don’t have much expertise with flame soldering, etc., wrote cuppajoe.

Is MAPP gas sufficiently hot to braze?

Any mapping gas larger than 3/8″ will not get it hot enough.

Before you begin soldering it, you must first heat it.

If he doesn’t want to invest in a torch equipment, you can utilize the glue-like substance.

I’m not sure what it’s called, but it’s something along the lines of a solderless bond.

When possible, I advocate using oxy/acetylene torches and 15 percent silver solder, although I did use that glue thing on a refrigerator today just to see how it worked.

It can withstand pressures of up to 850 psi, and I put it through a 300 psi nitrogen pressure test, which it passed.

Is propane butane or MAPP gas hotter to burn?

The hottest gas is MAPP, which is created by mixing liquid petroleum and methylacetylene-propadine. It burns at roughly 3650 degrees F, or 2010 degrees C. Brazing and hard or silver soldering are two of the best applications.
