Can cast iron be cut with oxy acetylene?

Generally, oxy-fuel torches are used for heavy metals such as steel and are frequently used in scrap yards to cut scrap metals. These torches should not be used to cut metals like cast iron, aluminum, or stainless steel.

Why is cast iron flame cutting difficult?

Cast iron is not readily flame cut, because the kindling temperature is above the melting point. It also has a refractory silicate oxide which produces a slag covering. When flame cutting, the preheating flame should be neutral or oxidising. A reducing or carbonising flame should not be used.

What is best way to cut cast iron?

But when cutting through solid cast iron, a saw or cutting tool with a diamond saw blade is the best choice to make a cut in a straight line.

Can gas cutting cut cast iron?

It doesn’t oxidize (turn into “rust”) as readily as steel which cuts very easily with oxygen and a flammable gas fuel, usually acetylene or propane are the most commonly used. Most cast iron objects will generally just get a coating of oxidation and not rust all the way through like items made from steel do.

What metals can oxy-acetylene cut?

Oxy-fuel torches are normally used for cutting only ferrous metals or those containing iron, such as carbon steel. For the most part, they are not used for cutting cast iron, aluminum or stainless steel. And while oxy-fuel torches aren’t dependent on primary power or compressed air, they do require purchase of gas.

Will an angle grinder cut cast iron?

The angle grinder is probably going to be your best bet for making cuts in the cast iron piece. The grinder offers the best option for getting the cuts where you want them and keeping them relatively smooth.

Can cast iron be cut with a plasma cutter?

The more energy added via the plasma cutter, the hotter the plasma arc becomes, providing more cutting capacity and efficiency. One of plasma’s greatest advantages is its ability to cut non-ferrous metals such as aluminum, stainless steel and cast iron, materials that are becoming more common in many applications.
