Single-stack batch annealing. Unlike continuous annealing, where the strip of steel is uncoiled, treated and rewound in approximately 15 minutes, batch annealing heats the coils intact in small furnaces over approximately 3 days. The coils are usually stacked four or five high on fixed bases, covered, and mobile furnaces lowered onto them.

Batch Annealing

The steels were found to be fully hardenable with conventional hot-strip mill processing and subsequent batch annealing simulations produced significant retained austenite levels. The combination of the prior martensitic microstructure in the as-hot-rolled condition, and austenite created during annealing, resulted in remarkable combinations of strength and ductility.
