Characteristics of 253MA

253MA is an austenitic stainless steel designed for high-temperature service, offering excellent oxidation resistance up to 1150°C (2100°F) and good creep strength. Its corrosion resistance in oxidizing environments is superior to standard 300-series stainless steels, thanks to its high chromium, silicon, and nitrogen content. The addition of rare earth elements like cerium enhances the stability of the protective oxide layer, making it ideal for cyclic thermal conditions.

While 253MA performs exceptionally in dry, high-temperature environments, it is not intended for prolonged exposure to reducing or carburizing atmospheres. Its corrosion resistance in aqueous environments is similar to that of Type 316 stainless steel.

Working with 253MA

253MA is typically supplied in the annealed condition, which provides good formability and weldability. Standard fabrication techniques for austenitic stainless steels apply, including TIG and MIG welding. Preheating is generally not required, but matching filler metals (such as 22.12HT) are recommended for weld integrity at high temperatures.

Heat treatment for 253MA is straightforward:

• Solution annealing is performed at approximately 1150°C (2100°F) followed by rapid cooling.
• This treatment ensures maximum oxidation resistance and mechanical strength for high-temperature service.

Unlike precipitation-hardening grades, 253MA does not rely on secondary hardening treatments. Its strength comes from solid solution strengthening and nitrogen additions, which maintain stability at elevated temperatures.
