Main characteristics of 1.2361 tool steel

1.2361 tool steel applications

1.2361 steel for Heavy-Duty Blanking Die

High carbon and chromium provide outstanding wear resistance, enabling 1.2361 to maintain clean cutting edges in blanking of thick or high-strength sheet metal.

1.2361 steel for Cold Shear Blade

Excellent edge stability and anti-chipping properties make 1.2361 ideal for cold shear blades cutting bars, profiles, and heavy-gauge plates with extended service life.

1.2361 steel for Precision Cold Forming Die

Good dimensional stability in heat treatment and high attainable hardness ensure consistent profile accuracy in precision cold forming of complex components.

mechanical properties & heat treatment of 1.2361 steel

Heat temperature	Start forging temperature	Finish forging temperature	Cooling method
1120 – 1150 °C	1100 – 1150 °C	≥ 950 – 927 °C	Pit, sand, or furnace cooling

Annealing

Heat slowly and uniformly to 810 – 860°C (780–840°C per some sources) and soak thoroughly
Hold at temperature for 2 – 5 hours, depending on section thickness
Cool slowly in the furnace at a controlled rate down to approximately 600°C
Then air cool to room temperature
Hardness after annealing: max. 265 HB (approx. 25–27 HRC)
Annealing in a protective atmosphere is recommended to reduce decarburization and surface scaling

Hardening

1.2361 (X91CrMoV18) is a martensitic stainless cold work tool steel with high carbon (approx. 0.90%) and high chromium (approx. 18.0%) content. It offers excellent corrosion resistance, high hardness (up to 56–58 HRC), and good wear resistance after heat treatment. Due to its high carbon content, machining characteristics are similar to high-speed steel (HSS). Temper immediately after quenching
Pre-heating (recommended): Pre-heat slowly to 600 – 750°C to avoid thermal shock before austenitizing
Austenitizing temperature: 1000 – 1050°C (1,000 up to 1,050°C).
Preferred hardening temperature: 1000–1050°C.
Hold at the specified temperature for 15–30 minutes after complete heating
Holding time: After temperature equalization, hold for 30 minutes per 25mm of section thickness. Maximum holding time at temperature is 30 minutes / 25mm cross-section
Quenching media: Oil (preferred) – quench immediately after holding.
Alternative: compressed air (not recommended for larger sections).
Do not use water quenching due to high cracking risk
Hardness after quenching: approx. 56 – 58 HRC.
SIJ data: hardness after quenching is 56 HRC.
MOYAN data: hardness after hardening is 58–60 HRC

Stress relieving

Perform after rough machining or heavy stock removal to reduce the risk of distortion during final heat treatment
Heat carefully to approx. 650°C and hold for 1 hour at temperature
After holding, air cool to room temperature
This operation is performed to reduce distortion during hardening

Tempering

Temper immediately after the workpiece cools to handwarm temperature (approx. 50–70°C). Delayed tempering may cause cracking
Number of tempers: Minimum 2 times. Double tempering is mandatory for this grade to ensure complete transformation of retained austenite and property stability. After each tempering cycle, cool to room temperature before the next tempering
Holding time: Soak for at least 2 hours after complete heating (minimum 2 hours per cycle)
Cooling method: Air cool after each tempering cycle
