Stainless Steel 310 Instrumentation Tubes are specially designed for high-performance applications where resistance to extreme temperatures and corrosive environments is critical. Manufactured from austenitic stainless steel grade 310 or its low-carbon variant 310S, these tubes offer superior mechanical properties and excellent oxidation resistance. They are widely used in industries such as chemical processing, power generation, oil & gas, and thermal processing, where high reliability and durability are essential.
One of the standout characteristics of SS 310 instrumentation tubes is their exceptional high-temperature strength. These tubes can withstand continuous exposure to temperatures up to 1100–1150°C (2010–2100°F) without losing their structural integrity. This makes them ideal for use in furnace tubes, heat exchangers, and thermal reactors where exposure to intense heat is a constant operational requirement. The 310S variant, with its lower carbon content, provides enhanced weldability and minimizes the risk of carbide precipitation during welding.
Stainless Steel 310 instrumentation tubes are typically manufactured to ASTM standards such as ASTM A213, A269, and A312, ensuring consistent quality, dimensional accuracy, and mechanical properties. They are available in various sizes, wall thicknesses, and finishes including seamless and welded options. Common finishes include bright annealed or polished surfaces, offering both aesthetic appeal and functional resistance to fouling or contamination in process environments.

Stainless Steel 310 instrumentation tubes are primarily used in high-temperature and corrosive environments such as instrumentation systems, heat exchangers, furnace parts, petrochemical plants, and power generation industries.
These tubes can typically withstand continuous operating temperatures up to around 1150°C (2100°F), making them ideal for extreme heat applications.
The main difference is carbon content: 310S has a lower carbon content (max 0.08%) which improves weldability and reduces carbide precipitation during welding, making it better for welded applications.
