AISI 410SS is one of the widely used martensitic steels. Tramp elements present in this steel segregate during tempering at prior austenite grain boundaries, which reduces the cohesive strength and results in intergranular cracking. Quenching and partitioning heat treatments stabilize minutes of austenite at room temperature. This reduces the segregation of tramp elements after prolonged aging and yields four to five times higher toughness compared with normalized and tempered steels. Thus, it provides resistance to cracking.

淬火和分配对AISI 410不锈钢的增韧以及长时间时效对组织和力学性能的影响

AISI 410SS是广泛使用的马氏体钢之一。在回火过程中，该钢中存在的流垒元素会在先前的奥氏体晶界处偏析，这会降低内聚强度并导致晶间开裂。淬火和分隔热处理可以在室温下稳定数分钟的奥氏体。与正火和回火钢相比，这可以减少长时间老化后流油元素的偏析，并且韧性高出四到五倍。因此，它提供了抗裂性。
