What is a hard nitriding cast iron?


A hard nitriding cast iron is created through a cross-between casting and stamping process.

Molten steel is deposited into the lower half of a pan mold, where it is “infused” with other components to harden the surface and increase the life of the mold by reducing deformation.

Nitriding, also known as hard nitriding, is a heat treatment process that improves the rust durability and resistance of stainless steel.

It entails applying a nitrogen-rich gas, such as ammonia, or a solid, such as sodium cyanide, to heated metal.

Is hard nitriding cast iron good?

Yes, it is. Properly seasoned cast iron is a perfect method for protecting a cooking pan.

However, when you nitrate it, it makes it more durable, which also makes maintenance simpler. If you take good care of it, it can last a lifetime.

How important is it to nitride cast iron cookware?

Your cast iron will last longer if it is nitrate. Additionally, because of the nitriding, the pan will require less maintenance.

Nonetheless, only a small number of cast iron varieties can be nitrogen-treated. Nitriding is, therefore, uncommon with cast iron cookware.

What are the benefits of nitrate cast iron for cooking?

Nitrate cast iron has a high level of rust resistance. Compared to conventional cast iron, it is also more non-stick.

Cast iron still needs to be seasoned to create a non-stick surface. However, food won’t adhere to your new pan when it is nitrate.

Cast iron that has been nitrate typically weighs less than regular cast iron, making cooking with it simpler.
