At Yalman Knives, the performance of our industrial blades is directly linked to the high-quality tool steels we use and the advanced heat treatment technologies we apply. For heavy-duty applications such as shredder blades, scrap shear blades, and granulator knives, material selection is the most critical factor determining service life.
The steels used in our blade production are sourced from globally recognized manufacturers:
Deutsche Edelstahlwerke (DEW)
SIJ Metal Ravne
Böhler Tool Steel
These alloy tool steels are known for their purity, homogeneous internal structure, and controlled chemical composition, providing high impact resistance, wear resistance, and mechanical stability in demanding recycling applications.
Yalman Knives selects steel grades according to application requirements. For high-torque shredders and scrap shear systems operating under extreme loads, we use alloys designed to provide:
High toughness
Controlled hardenability
Resistance to crack propagation
Dimensional stability after heat treatment
This ensures longer blade life and reliable field performance.
Steel quality alone is not enough — heat treatment defines final performance. All Yalman Knives products undergo in-house vacuum heat treatment, ensuring full process control.
Advantages of vacuum heat treatment:
✔ Uniform hardness distribution
✔ Oxidation-free surfaces
✔ Reduced residual stresses
✔ Lower micro-crack risk
✔ Controlled hardness–toughness balance
This metallurgical balance allows our blades to operate under heavy loads without premature failure.
Heat treatment can cause micron-level distortions that affect performance. Therefore, all blades undergo:
Post Heat Treatment Machining
Precision grinding
Mounting surface flatness control
This guarantees perfect contact surfaces, balanced load distribution, and vibration-free operation in the machine.
At Yalman Knives, quality is a continuous chain:
Premium steel sourcing → precision CNC machining → vacuum heat treatment → post heat treatment machining → final quality inspection
This integrated approach ensures:
Longer service life
Stable cutting performance
Predictable wear behavior
Reduced downtime
Yalman Knives combines premium European tool steels with advanced heat treatment technology to deliver reliable, long-lasting cutting solutions for the recycling and metal processing industry.
