What temperature should you forge at?

While typical hot forging temperatures are between 2150°F and 2375°F – well below the melting temperature of more than 2500°F – deformation (adiabatic) heating results in local heating.

What is a good forge welding temperature?

Pure iron can be welded when nearly white hot; between 2,500 °F (1,400 °C) and 2,700 °F (1,500 °C). Steel with a carbon content of 2.0% can be welded when orangish-yellow, between 1,700 °F (900 °C) and 2,000 °F (1,100 °C). Common steel, between 0.2 and 0.8% carbon, is typically welded at a bright yellow heat.

How hot do you have to get steel to forge it?

Iron, out of the ground, melts at around 1510 degrees C (2750°F). Steel often melts at around 1370 degrees C (2500°F).

At what temp does steel glow yellow?

Between 1000 degrees Fahrenheit and 1500 degrees Fahrenheit, steel turns an increasingly brighter shade of red. Between 1600 degrees Fahrenheit and 1900 degrees Fahrenheit, steel turns orange and then yellow. At 2000 degrees Fahrenheit, steel turns bright yellow.

Are forge welds strong?

It leads to a weld seam that comprises the welded metals only, and has no bridging or filler materials. The creation of a lower melting temperature between the materials causes forge welding between distinct metals. For this reason, the weld seam is usually strong as compared to the individual metals.

How hot will a propane forge get?

The combustion temperature of propane is 1,967 degrees F for combustion with air and 2,526 degrees for combustion with pure oxygen (The Engineering ToolBox). Typical forge welding temperatures for a propane forge are accepted as 2,300 degrees F, and common forging can be accomplished at a lower temperature.

How hot can a wood forge get?

Wood burns up to about 1,148℉ (620℃). This is not nearly as hot as the coal forge, but it's still hot enough to melt some types of metal.

How hot is it on forged in fire?

Meanwhile, the forges and other heating equipment used by the smiths are capable of running well above one thousand degrees Fahrenheit, according to a tour video uploaded on YouTube by the History Channel. This, combined with all of the lighting equipment, makes the set an extremely hot place.

What is the best fuel for a forge?

Coal and propane are the most typical fuels used in blacksmith forges. On the East Coast, coal is readily available and therefore more affordable than on the West Coast. Coal burns more efficiently and hotter than wood. Because of its efficiency, the volume of coal needed is substantially less, too.

What type of coal is best for a forge?

Bituminous Coal

This soft, black fossil fuel is the preferred forging coal of most blacksmiths. It has a low sulfur content. This is important because sulfur lowers the quality of the coke, rendering brittle any steel item it comes in contact with.

Can you use BBQ charcoal in a forge?

Charcoal is considered the least desirable fuel when blacksmithing. While readily available, charcoal may not even reach the necessary temperature to soften iron and steel without a lot of fuel and constant airflow. You can burn through a lot of charcoal quickly and still not achieve the proper temperatures.

What PSI should I run my forge?

Both forges run several hundred degrees hotter. How much propane will these forges use? That depends on the pressure that the burners are being run at. The burners can run efficiently across a pressure range of 3- 20 PSI.

How high should your forge be?

Approximately same height as anvil the general-purpose forge hearth is level with the smiths knuckles or second finger joint. As an example, my forges are about 1/2 inch taller than my anvils with the actual measurement of height of hearth being about 31-1/2 tall above the floor.

What is the best refractory for a forge?

Highly flux resistant! This material works really well for coating an Inswool lined forge for protection against flux when forge welding. This is one of the most flux resistant coatings we have found to date!

What does borax do to metal while forging?

A mixture of borax and ammonium chloride is used as a flux when welding iron and steel. It lowers the melting point of the unwanted iron oxide (scale), allowing it to run off, to keep the metals clean during the forging process.

What is the powder they use on forged in fire?

Blacksmiths use borax as a flux, which is an agent that cleans and purifies the metal being joined in the forge welding process. This enables a high-quality weld.

Can you over temper steel?

While you can definitely over-temper a blade, that will leave it too soft rather than too brittle; you can also over-harden (or, rather, under-temper) it, which will leave it very hard and very brittle.

At what temperature does steel turn purple?

Heat the steel to temperatures from 400 to 800 degrees Fahrenheit, to produce oxidation colors. At 480 degrees F., the steel turns brown, at 520 degrees, it turns purple, at 575 degrees, it turns blue and at 800 degrees, it turns grey. These temperatures are commonly used in tempering tool steel.

What oil do you use to quench a blade?

There are many food-grade quenching oil options available to use for blacksmithing. Among these options are vegetable, peanut, and avocado oil. Some commonly used vegetable oils are canola, olive, and palm kernel oil. Vegetable oil is very cheap and comes from renewable sources.

What is forge coke?

FORGING COKE. Maximum heat, famously clean burning, and low clinker. Premium Metallurgical COKE burns much hotter and cleaner than coal. Especially processed and sized for use in blacksmith and farrier forges.
