Description
M35 Steel Round Bar, DIN 1.3243, JIS SKH55, Extraordinary Physical Properties.
DIN 1.3243 (also known as HS6-5-2-5 or M35) is a high-speed tool steel with excellent hardness, toughness, and red hardness.
It is an alloyed steel with tungsten (W), molybdenum (Mo), vanadium (V), cobalt (Co), and chromium (Cr), making it ideal for high-performance cutting tools.
Chemical Composition of DIN 1.3243 ,M35 steel round bar and JIS SKH55
| Element | Content (%) |
|---|---|
| Carbon (C) | 0.88 – 0.94 |
| Chromium (Cr) | 3.8 – 4.5 |
| Molybdenum (Mo) | 4.5 – 5.5 |
| Vanadium (V) | 1.7 – 2.1 |
| Tungsten (W) | 5.8 – 6.5 |
| Cobalt (Co) | 4.5 – 5.0 |
| Silicon (Si) | ≤ 0.75 |
| Manganese (Mn) | ≤ 0.40 |
| Sulfur (S) | ≤ 0.030 |
Key Properties
- High Hardness: Can reach up to 64-66 HRC after heat treatment.
- Excellent Wear Resistance: Due to carbide-forming elements like W, Mo, and V.
- Good Toughness: Improved over M2 due to the presence of cobalt.
- Superior Red Hardness: Maintains hardness at high temperatures, making it ideal for cutting applications.
- High Compressive Strength: Suitable for demanding machining operations.
Applications
- High-performance cutting tools (e.g., drills, end mills, taps, and reamers)
- Broaches and form-cutting tools
- Cold working tools (punches, dies)
- Industrial knives and saw blades
- Aerospace and automotive applications
Heat Treatment Process
- Annealing:
- Heat to 850-900°C, then slow cooling in the furnace.
- Ensures machinability and stress relief.
- Hardening:
- Preheat at 450-500°C and 850-900°C.
- Austenitizing at 1180-1230°C, followed by quenching in oil or salt bath.
- Tempering:
- Heat to 540-560°C, hold for 1 hour per 25mm of thickness.
- Perform 2-3 tempering cycles for optimal toughness and hardness.

M35 Steel Annealing Process.
If you case it up for the annealing after the forging, you will get a higher result.
In case you can not try this, simply make it bloodless to the indoor temperature then make it in.
In case you can not try this, simply make it bloodless to the indoor temperature then make it in.
About the annealing system, simply placed it within the range with the temperature that is lower than 500℃.
Then heat to 840-860℃, preserve the temperature for 4 to 5 hours.
That allows you to prevent oxidative decarburization show up, the annealing have to be careful.
And there is an easy manner can try this.
Just put a few wooden dirt to the annealing furnace.
Furnace cooling to 500℃ underneath than out of it.
Cooling slowly inside the annealing furnace.
After the annealing, its hardness is lower than 255hb.
