The tempering time for 1095 steel can vary depending on factors such as the desired hardness and toughness, the specific heat treatment recipe used, and the dimensions of the steel. However, a typical range for tempering time for 1095 steel is between 1 to 2 hours.

During tempering, the hardened steel is heated to a lower temperature to reduce brittleness and improve toughness. The exact tempering temperature and time within the range will depend on the desired balance between hardness and toughness. The tempering temperature for 1095 steel is typically between 150°C (300°F) and 260°C (500°F).

To determine the appropriate tempering time for your specific application, it's important to consider factors such as the desired hardness, the dimensions of the steel, and the specific heat treatment recipe you are following. It's advisable to consult with an experienced metallurgist, heat treatment specialist, or refer to established heat treatment guidelines for 1095 steel to ensure the desired properties are achieved.
