253MA Stainless Steel Seamless Pipe with High Temperature Resistance, Corrosion Resistant, and Austenitic Structure
253MA is a high-performance austenitic stainless steel grade that combines excellent high-temperature service properties with ease of fabrication. This seamless steel pipe in UNS S30815 specification offers superior oxidation resistance up to 1150°C and outperforms Grade 310 in carbon, nitrogen, and sulphur-containing atmospheres.
- Optimized nickel content provides advantages in reducing sulphide atmospheres
- High silicon, nitrogen, and cerium contents ensure excellent oxide stability
- Superior elevated temperature strength and creep resistance
- Excellent resistance to sigma phase precipitation
- Maintains excellent toughness even at cryogenic temperatures
