Main characteristics of 1.2358 tool steel

1.2358 tool steel applications

1.2358 steel for Heavy-Duty Cold Shear Blade

High carbon and elevated chromium content deliver exceptional wear resistance and edge stability, making 1.2358 ideal for shearing high-strength or thick-gauge steel plates.

1.2358 steel for Cold Rolling Mill Roll

Excellent deep hardenability and high compressive strength ensure lasting surface integrity under the extreme contact stresses of cold strip rolling.

1.2358 steel for Precision Cold Extrusion Die

Superior anti-galling properties and dimensional stability under load enable precise, high-volume cold extrusion of complex steel components with extended die life.

mechanical properties & heat treatment of 1.2358 steel

Heat temperature	Start forging temperature	Finish forging temperature	Cooling method
1050 – 1100 °C	1000 – 1050 °C	≥ 850 °C	Pit, sand, or furnace cooling

Annealing

Heat slowly and uniformly to 820 – 860°C (1508 – 1580°F)
Hold at temperature for 2 – 5 hours, depending on section thickness and workpiece size
Cool slowly in the furnace to room temperature, or cool at a controlled rate down to approximately 600°C and then air cool
Hardness after annealing: max. 240 HB (approx. 22–23 HRC)
Annealing in a protective atmosphere is recommended to reduce decarburization

Hardening

1.2358 is a chromiummolybdenumvanadium alloyed cold work tool steel. It offers a good combination of high toughness, high wear resistance, good hardenability, and excellent dimensional stability after heat treatment. The steel has good throughhardenability and very good surface hardening properties. Temper immediately after quenching.
Pre-heating (recommended): Pre-heat slowly to 600 – 750°C to avoid thermal shock during austenitizing
Austenitizing temperature: 950 – 980°C (1742 – 1796°F).
Preferred range: 950–970°C for oil or salt bath quenching.
Alternative: 980–1010°C (air or oil quenching) per SIJ data
Holding time: After temperature equalization, hold for 15 – 30 minutes (or 30 minutes per 25mm of section thickness)
Quenching media:
Oil (preferred for most sections)
Pressure gas (N₂)
Air (for small sections)
Hot bath at 500–550°C (martempering for complex shapes)
Hardness after quenching: Approx. 60–65 HRC (typically 60–64 HRC)

Stress relieving

Perform after rough machining or heavy stock removal, especially for tools with complex shapes or unbalanced cross-sections, to reduce the risk of distortion during final heat treatment
Heat carefully to 600 – 650°C (1112 – 1202°F)
Hold at temperature for 1 – 2 hours (or 2 hours per 25mm of section thickness)
Cool slowly in the furnace, or after holding, air cool
For prehardened material, stress relieving at 500 – 550°C is possible
This operation is performed to relieve stresses set up by extensive machining or complex shapes

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 recommended to improve toughness and ensure complete transformation, with intercooling to room temperature between cycles
Holding time: Soak for at least 1 hour per 20mm of section thickness (minimum 2 hours per cycle)
Cooling method: Air cool after each tempering cycle (must cool to room temperature before the next tempering)
