Which of the following can be affected by 885º F Embrittlement?
Which of the following can be affected by 885º F Embrittlement?
885º F embrittlement, also known as sigma phase embrittlement, occurs predominantly in ferritic stainless steels such as the 400 series (which includes 410 SS and 430 SS) and duplex stainless steels like Alloy 2205. Austenitic stainless steels like the 300 series (including 308 SS) are generally not affected by this phenomenon. Therefore, the materials that can be affected by 885º F embrittlement include 410 SS, 430 SS, and Alloy 2205, making A, B, and D the correct options.
Affected materials : - 400 series SS - Duplex stainless steels such as 2205, 2304, and 2507 - Austenitic stainless steels (300 series)
