Product Description

  UNS S30815 253ma stainless steel Pipe

253MA is a grade combining excellent service properties at high temperatures with ease of fabrication. It resists oxidation at temperatures up to 1150°C and can provide superior service to Grade 310 in carbon, nitrogen and sulphur containing atmospheres.

Another proprietary designation covering this grade is 2111HTR.

253MA contains fairly low nickel content, which gives it some advantage in reducing sulphide atmospheres when compared to high nickel alloys and to Grade 310. The inclusion of high silicon, nitrogen and cerium contents gives the steel good oxide stability, high elevated temperature strength and excellent resistance to sigma phase precipitation.

The austenitic structure gives this grade excellent toughness, even down to cryogenic temperatures.

These comparisons are approximate only. The list is intended as a comparison of functionally similar materials not as a schedule of contractual equivalents. If exact equivalents are needed original specifications must be consulted.

Possible Alternative Grades

Possible alternative grades to grade 253MA stainless steels are given in table 5.

 

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.
