253mA/UNS S30815/DIN 1.4835/DIN 1.4845 Stainless Steel Pipes

UNS S30815 253MA stainless steel pipe combines excellent high-temperature service properties with ease of fabrication. This grade resists oxidation at temperatures up to 1150°C and provides superior performance to Grade 310 in carbon, nitrogen, and sulphur-containing atmospheres.

Also known as 2111HTR, 253MA contains relatively low nickel content, offering advantages in reducing sulphide atmospheres compared to high nickel alloys and Grade 310. The inclusion of high silicon, nitrogen, and cerium contents provides excellent oxide stability, high elevated temperature strength, and superior resistance to sigma phase precipitation.

The austenitic structure ensures excellent toughness, even at cryogenic temperatures.

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
