Product Description
253MA Stainless Steel Plate - UNS S30815
253MA is a high-temperature stainless steel grade combining excellent service properties with ease of fabrication. It resists oxidation at temperatures up to 1150°C and provides superior performance to Grade 310 in carbon, nitrogen, and sulphur-containing atmospheres.
Key Features and Benefits
- Excellent oxidation resistance up to 1150°C
- Superior performance in carbon, nitrogen, and sulphur atmospheres
- Good oxide stability and high elevated temperature strength
- Excellent resistance to sigma phase precipitation
- Maintains toughness even at cryogenic temperatures
- Lower nickel content provides advantage in reducing sulphide atmospheres

Possible Alternative Grades
| Grade | Why it might be chosen instead of 253MA |
|---|---|
| 310 | Carburising atmospheres require a higher nickel content |
| 304H | Lower cost alternative, provided the operating temperature is below about 800°C |
| Nickel Alloys | Carburising atmospheres or temperatures above the 1100-1150°C maximum of 253MA |
