CNC machined S7 tool steel parts for high-wear applications
There are several advantages of the Annealed S7 tool steel in CNC components.
Better surface finish on machine products
- Less wear of milling and turning tools
- Reduction of energy used in cutting
- Improved chip control
Machinability of Annealed 50CrMoV13-15
The machinability of annealed 50CrMoV13-15 is rated between 75-80% of W1 tool steel. It enables effective roughing, finishing, and detailing accuracy in CNC procedures.
Important Machinability Notes:
- Get the best tooling using carbide
- They are advised to use dry machining or mist lubrication
- Surface speeds of 25-35m/min are best
For tolerances machining 1.2355 steel, S7 allows for precise control. This steel maintains narrow tolerances after machining, and it delivers good even in critical tolerance areas.
Annealed to Hardened Heat Treatment of S7 Tool Steel
When the machining process is over, a hardening step is performed to harden the S7 tool steel annealed part through heat treatment. The process will make the part wear-resistant without abrasiveness.
Heat Treatment Process
- Double Burning
- Warm to 600 650 °C (1110 1200 1200°F)
- Austenite to 925 980 o C (1700 1800 o F)
- Air or oil quench
- Temper 150 400 °C – To attain the hardness required
Post-heat treatment, components made from CNC machined S7 tool steel parts can reach 56–58 HRC hardness.
