Can Stainless steel be Used in High Temperature?
Can Stainless steel be Used in High Temperature? Most important quality of Stainless Steel is its Corrosion Resistance and next is its ability to withstand heat. Stainless steels are also found in applications where high-temperature oxidation resistance is critical, and in other applications where high-temperature strength is required. The high chromium content which is so beneficial to the wet corrosion resistance of stainless steels is additionally highly beneficial to their high-temperature strength and resistance to scaling at elevated temperatures Scaling Resistance Scaling relies on the chromium content present in the stainless steel within the same way the corrosion resistance is. Most martensitic and ferritic steels have lower resistance to oxidation and hence lower useful operating temperatures. An exception to the present is that the ferritic grade 446 - this has approximately 24% chromium and might be used to resist scaling at temperatures up to 1100u00b0C. Creep Strength The high-temperature strength of materials is mostly expressed in terms of their "creep strength" the power of the material to resist distortion over long run exposure to a high temperature. The low carbon versions of the standard austenitic grades (Grades 304L and 316L) have reduced strength at high temperature so are not generally used for structural applications at elevated temperatures. "H" versions of every grade (eg 304H) have higher carbon contents for these applications, which ends up in significantly higher creep strengths. "H" grades are specified for a few elevated temperature applications. Below table shows the approximate maximum service temperatures at which the various grades of stainless steels can be used to resist oxidation in dry air.

The thing to consider is, a metal alloy might have different tolerances for exposure to high temperatures depending on whether said exposure is continuous or intermittent. You may have noticed an odd and potentially counterintuitive trend for the 300-series stainless-steel alloys listed here. Specifically, their continuous recommended maximum use temperature is beyond their periodic, intermittent use temperature limits. It's natural to assume that exposing the metal to high temperatures for a shorter time would place less strain on that than longer exposure would.
