AISI 1095 Steel


Recommended Working Sequence For 1095

Forging

When forging heat to 2100°F (1150°C). Do not forge below 1500°F (815°C).

Normalizing: Heat to 1575°F (855°C). Cool in still air.

Annealing: Heat to 1475°F (800°C). Furnace cool to 1200°F (650°C) at a rate not exceeding 50°F (28°C) per hour.

Grinding or Machining

Hardening: Austenitize- Heat to 1475°F (800°C) soak for 5 minutes then quench in a fast oil like #50 Parks.
Thicker sections can be quenched in water or brine with extreme care but oil quenching sections under 3/16 in. (5 mm) thick is the preferred method.

Tempering: As-quenched hardness of approximately 66 HRC can be achieved with a fast oil. Canola oil is a bit slower and the hardness is lower, in the range of 64 - 65 Rhc.

Stock Removal

Material comes from the supplier in the Spheroidized annealed state and is ready for working.

Grinding, Drilling or Machining

Hardening: Austenitize- Heat to 1475°F (800°C). In thicker sections can be quenched in water or brine with extreme care but can also be oil quenched in sections under 3/16 in. (5 mm) thick as the preferred method.


Tempering: As-quenched hardness of approximately 66 HRC. Hardness can be adjusted downward by proper tempering.
