Drying ovens are indispensable in laboratories and industrial production. Among their components, the stainless steel inner chamber plays a critical role in ensuring durability and performance. While traditional ovens might use non-stainless materials, all our drying ovens feature fully stainless steel chambers to guarantee long-lasting use and optimal results. These stainless steel chambers are available in three main grades: SUS201, SUS304, and SUS316L. Below, we'll discuss their characteristics, applications, and differences.
SUS201
Features
SUS201 stainless steel contains a higher manganese content, offering reasonable corrosion resistance and good mechanical properties. Due to its relatively low cost, it is commonly found in budget-friendly drying ovens.
Advantages
• Cost-effective with a high performance-to-price ratio.
• Provides moderate corrosion and oxidation resistance.
• Good mechanical properties, suitable for basic drying needs.
Disadvantages
• Lower corrosion resistance compared to SUS304 and SUS316L.
• Prone to oxidation in high-temperature environments.
Applications
SUS201 stainless steel is typically used in economical drying ovens for environments with minimal corrosion demands, such as small laboratories or educational equipment. However, due to its susceptibility to rust and suboptimal drying performance, this material is now rarely used in production.
SUS304
Features
SUS304 is the most commonly used stainless steel, composed of 18% chromium and 8% nickel. It provides excellent corrosion resistance, oxidation resistance, and mechanical strength, making it ideal for various applications.
Advantages
• Superior corrosion and oxidation resistance.
• Exceptional mechanical strength and long lifespan.
• Maintains stable performance across a wide temperature range.
Disadvantages
• Higher cost compared to SUS201.
Applications
SUS304 stainless steel inner chambers are widely used in drying ovens where higher corrosion resistance and durability are required. Typical industries include pharmaceuticals, food processing, and chemical production. All our drying ovens use SUS304 as the standard material, ensuring optimal performance and longevity.
SUS316L
Features
SUS316L is the premium option among these three grades. It is a low-carbon stainless steel with 2% molybdenum, offering exceptional resistance to corrosion and oxidation. The reduced carbon content minimizes the risk of carbide precipitation during welding, enhancing its weldability.
Advantages
• Outstanding corrosion and oxidation resistance.
• Excellent mechanical strength and weldability.
• Ideal for use in extreme environments.
Disadvantages
• All good expect the price :P
Applications
SUS316L is often used in drying ovens designed for highly corrosive environments or extreme conditions, such as marine applications or chemical processing involving aggressive substances. While SUS304 is sufficient for most general-purpose ovens, we offer customization with SUS316L inner chambers upon request to meet specific client needs.
