What steel are wood stoves made of and which one is better suited for this?

Wood-burning stoves made of metal are an excellent combination of strength, efficiency, and aesthetic design. Here are some of the unique metal materials commonly used in creating such stoves:


Cast Iron: wood-burning stoves have long been a symbol of tradition and reliability. Cast iron possesses excellent heat-retaining properties, allowing it to retain and evenly distribute heat within the stove. This material is also resistant to high temperatures and provides durability to the stoves.


Steel: wood-burning stoves offer a modern approach to heating. Steel is lightweight, strong, and allows for elegant and minimalist designs. With high thermal conductivity, steel stoves heat up quickly and evenly distribute warmth throughout the room.

Our stoves are made of 3mm thick carbon steel:

Stainless Steel: this type of steel has a high degree of corrosion resistance, making it ideal for use in wood-burning stoves. Stainless steel performs well under high temperatures and provides durability and reliability to the stove.


Heat-Resistant Steel: this steel is often used for stoves intended for intensive use and high temperatures. This material has a high degree of heat resistance and durability, making it ideal for creating professional stoves used in restaurants or bakeries.

Regardless of the chosen metal, wood-burning stoves made of metal provide efficient heating and a pleasant atmosphere. They combine strength and functionality, allowing you to enjoy the warmth and beauty of the flames in a cozy home environment.

When choosing a steel grade for wood-burning stoves, it is important to consider several factors such as thermal conductivity, heat capacity, strength, and resistance to high temperatures. Here are a few steel grades commonly used in the manufacturing of wood-burning stoves:


S235 Steel: steel grade is a general structural steel known for its good strength and weldability. It is commonly used in the production of medium-sized wood-burning stoves. S235 steel has moderate thermal conductivity and can provide reliable stove performance when used correctly.


Stainless Steel (e.g., AISI 304 grade): stainless steel is known for its high corrosion resistance, making it an ideal choice for wood-burning stoves. The AISI 304 grade is the most common stainless steel grade and offers good strength and thermal conductivity. Stainless steel may be more expensive, but it provides durability and reliability to the stove.


Heat-Resistant Steel (e.g., 16Mo3 grade): heat-resistant steel exhibits a high level of heat resistance and is used in stoves operating at very high temperatures. The 16Mo3 grade is widely used in thermal engineering and may be suitable for wood-burning stoves where high temperatures are a critical factor.


Among the provided materials - cast iron and heat-resistant steel - cast iron is generally considered a more durable material for wood-burning stoves. Cast iron stoves are known for their longevity and durability. They can withstand high temperatures, are resistant to thermal expansion, and possess excellent heat-retaining properties.

Cast iron has high heat capacity, allowing it to heat up slowly and evenly distribute warmth throughout the room. This promotes more efficient fuel utilization and provides prolonged heat even after the fire has extinguished. Additionally, cast iron stoves typically have thick walls, ensuring stability and structural durability.

Heat-resistant steel is also a strong and durable material, especially when it comes to high temperatures. However, compared to cast iron, heat-resistant steel may be more susceptible to corrosion and requires more careful care and maintenance.

It's important to note that the durability of a stove depends not only on the material but also on the quality of manufacturing, proper operational maintenance, and regular care. Regular cleaning and removal of soot, as well as proper usage and storage, will help prolong the lifespan of any material used in the construction of wood-burning stoves.

Heat dissipation of a wood-burning stove from the selected material

The heat transfer of materials such as cast iron and steel depends on their thermal conductivity and heat capacity. Both materials have different properties in this regard:


Cast iron possesses excellent thermal conductivity and high heat capacity, allowing it to heat up slowly and evenly distribute warmth throughout the stove. This ensures long-term heat retention and transfer into the room even after the fire has extinguished. Cast iron stoves can have high heat output and effectively heat larger spaces.

Steel also has good thermal conductivity, although slightly lower than that of cast iron. However, steel stoves can heat up faster due to the lower heat capacity of the material. They can provide good heat transfer and efficiently heat the room.

An equally important role is played by the type of firewood used to fire stoves.

In this article, we have analyzed in detail the types of wood used for fireboxes.

It's important to note that the heat transfer of a stove also depends on its design and construction, including the placement of heat exchange surfaces, the surface area for heat exchange, and the efficiency of heat distribution in the room. These factors can vary among different stove models and manufacturers, so it is recommended to refer to the specifications of specific stove models for more accurate information about their heat transfer capabilities.

Thickness of metal for wood stove

The optimal thickness of steel for wood-burning stoves can vary depending on several factors, such as the size of the stove, its construction, efficiency, and required heating characteristics. Here are some general considerations that can help in choosing the optimal steel thickness:


Strength: the steel thickness should be sufficient to provide adequate strength and stability to the stove during operation. Thicker steel can offer greater strength but may also increase the weight of the stove. It is recommended to consult the stove manufacturer or an engineer to obtain recommendations regarding the optimal steel thickness for a specific stove model.


Heat transfer: the steel thickness can also impact the heat transfer of the stove. The thickness of the stove walls can affect the heating speed and heat distribution. Thin steel may heat up faster but may distribute heat less evenly. Thicker steel can provide more even heat distribution but may require more time to heat up.


Fuel efficiency: the steel thickness can also influence the fuel efficiency of the stove. Thicker steel can offer better heat insulation, helping to retain heat inside the stove and improve combustion efficiency. However, the thickness of the stove walls should be balanced considering good air circulation and sufficient oxygen supply to ensure complete fuel combustion.

It is advisable to consult the stove manufacturer or a specialist in the field of heating equipment to determine the optimal steel thickness for a specific stove model, taking into account all necessary factors and requirements.
