Difference between ovens for different materials - Jiangsu Ruiyuan Heating Equipment Technology Co.

As a common industrial equipment, ovens are widely used in all kinds of drying, baking, curing and other production processes. Ovens made of different materials vary in terms of performance, durability and scope of application. Understanding these differences will help you choose the right oven material according to your actual needs. In this article, we will analyse the differences between stainless steel ovens and aluminium ovens, and introduce suitable oven materials for high temperature applications.

1. Difference between stainless steel oven and aluminium oven

(1) corrosion resistance

Stainless steel oven: Stainless steel has excellent corrosion resistance and is resistant to most chemicals. This makes stainless steel ovens ideal for use in the chemical, pharmaceutical and food processing industries, where equipment is often exposed to humid or corrosive atmospheres.
Aluminium oven: Although aluminium also has a certain degree of corrosion resistance, compared to stainless steel, corrosion resistance is poor, especially in contact with acidic or alkaline chemicals are prone to corrosion. Therefore, aluminium ovens are more suitable for application scenarios with milder environments.

(2) Strength and durability

Stainless steel oven: Stainless steel is stronger and can withstand greater impact and pressure. Therefore, stainless steel ovens are usually used in some application scenarios that require high strength and wear resistance.
Aluminium oven: Aluminium is a relatively lightweight material with low strength and is not suitable for large impacts or high loads. Therefore, aluminium ovens are more suitable for scenarios that do not require high strength, such as some small laboratory applications.

(3) High temperature resistance

Stainless steel oven: Stainless steel has better high temperature resistance and can work stably at higher temperatures. Especially some high temperature drying, heat treatment and other applications, stainless steel oven can better meet the requirements.
Aluminium oven: Aluminium has a relatively weak resistance to high temperatures and is generally susceptible to deformation or damage at higher temperatures. Aluminium ovens are usually used for low or medium temperature drying applications and are suitable for production environments with low temperature requirements.

(4) thermal conductivity

Stainless steel oven: Stainless steel has relatively poor thermal conductivity, but its durability is strong, so in environments that require long-term high-temperature operation, stainless steel can still ensure the long-term stability of the equipment, even though its thermal conductivity is not as good as that of aluminium.
Aluminium oven: Aluminium has very good thermal conductivity and can reach the required temperature much faster, making aluminium ovens more advantageous in applications where the speed of heating is important.

(5) Appearance and maintenance

Stainless steel oven: Stainless steel ovens usually have a smooth surface that is easy to clean and maintain, especially in industries with high hygiene requirements, such as the food industry, where stainless steel is ideally suited.
Aluminium oven: Aluminium ovens tend to leave marks on the surface and are less convenient to clean, especially in industries that require high hygiene standards, where aluminium may not be as popular as stainless steel.

2. Oven materials suitable for high temperatures

For ovens that need to operate in high-temperature environments, choosing the right material is critical. In general, the following materials are suitable for high temperature ovens:

(1) stainless steels

Stainless steel is widely used in the manufacture of high temperature ovens due to its high temperature resistance and corrosion resistance. Stainless steel types 304 and 316, in particular, are able to withstand temperatures of up to 800°C, making them ideal for use in industrial environments where high temperatures are required for extended periods of time.

(2) foundry iron

Cast iron also has a good resistance to high temperatures, especially in some specialised industrial heating equipment, where it is able to withstand high levels of heat and maintain a stable performance. Despite its heavier weight, it is still very effective in some industrial applications.

(3) Ceramic materials

Ceramic materials have excellent heat resistance properties and can withstand temperatures in excess of 1,000°C. For this reason, ceramic ovens are often used in specialised areas such as aerospace and high-temperature furnaces for very high-temperature heating processes.

(4) silicon carbide

Silicon carbide is a material that can withstand very high temperatures (over 1600°C) and is commonly used in ovens in some extreme high temperature environments, such as high temperature furnaces in the metallurgical industry.

In conclusion, there are significant differences in the performance of ovens made of different materials, and choosing the right oven material depends on the application scenario, heating temperature and industry needs. If your needs include heating and stability in a high-temperature environment, choosing a high-temperature-resistant material such as stainless steel or ceramic would be a wise move.
