Introduction
Stainless steel grade 353MA is an alloy with higher nickel content than the other steels. Max service temperature in air for this alloy is 1150°C (2102°F); however service below 950°C (1742°F) may cause reduced room temperature impact toughness.
The following datasheet provides an overview of stainless steel grade 353MA.
