--Comparison of High-Temperature Performance and Analysis of Applicable Scenarios
When choosing materials for high-temperature applications, the performance levels of 309, 304, and 310S stainless steels are distinct, and their applicable scenarios are also different:
304 stainless steel: It has strong versatility, but its long-term operating temperature should not exceed 870℃. It is prone to oxidation at high temperatures and is suitable for general heat-resistant components.
309 stainless steel: Specifically designed for continuous operation at temperatures below 980℃, it exhibits excellent resistance to oxidation and carbon penetration. It is an ideal choice for components in heat treatment furnaces and heat exchangers, with high cost-effectiveness.
310S stainless steel: With a higher chromium and nickel content, its continuous operating temperature can reach 1150℃. It performs best in extreme high-temperature and cyclic heating environments and is commonly used in core high-temperature components such as radiation tubes and combustion chambers.
Summary: Select 304 for basic heat resistance, select 309 to cope with continuous high-temperature and corrosive atmospheres, and select 310S to challenge extreme high temperatures.
