The Heat Resistance of SUS410 Stainless Steel Plate

SUS410 stainless steel plate, a martensitic stainless steel defined under JIS G4304, is well regarded for its ability to withstand moderate heat while maintaining mechanical strength and corrosion resistance. This unique balance makes it a reliable material for applications exposed to elevated temperatures.
The chromium content of SUS410, typically around 11.5–13.5%, plays a vital role in its heat resistance. This alloying element helps form a protective oxide layer on the steel surface, reducing scaling and oxidation when subjected to high-temperature environments. As a result, SUS410 stainless steel plate performs well in conditions such as steam, hot water, and mildly corrosive atmospheres.
In terms of temperature limits, SUS410 stainless steel plate generally demonstrates stability up to about 650°C under intermittent service. Prolonged exposure at such temperatures, however, may reduce toughness due to its martensitic structure. For this reason, proper heat treatment, such as tempering, is often applied to balance hardness with thermal stability.
Practical applications of its heat resistance include turbine blades, valves, pump parts, and boiler components. These products benefit from the alloy’s ability to maintain both structural integrity and corrosion protection under heat stress.
In conclusion, SUS410 stainless steel plate offers reliable heat resistance, particularly for medium-temperature service. Its combination of thermal stability, durability, and moderate corrosion resistance makes it a valuable choice in both industrial and engineering applications.
