Descrizione di prodotto

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
