High-end breaker cylinder material SCM415

At METDEEM^TM,One standout choice for cylinder barrels (main cylinders) is SCM415 alloy steel—a Japanese-standard chromium-molybdenum (Cr-Mo) steel known for its excellent carburizing properties, wear resistance, and impact toughness.

Corresponding to the Chinese designation 15CrMo,SCM415 boasts high thermal strength and oxidation resistance. After carburizing heat treatment, its surface hardness can reach HRC62-64, making it suitable for wear-resistant components such as cylinders and pistons.

Key Advantages of SCM415 for Cylinders:

**Superior Surface Hardness**

After carburizing and quenching, SCM415 achieves a surface hardness of HRC 62-64, making it highly resistant to abrasion—critical for hydraulic hammer cylinders exposed to constant friction.

**Tough Core for Impact Resistance**

While the surface is hardened, the core retains a hardness of HRC 30-40, ensuring resistance to cracking under high dynamic loads.

**Machinability & Heat Treatability**

SCM415 is easier to forge, machine, and heat-treat compared to higher-carbon steels like SCM440, reducing manufacturing costs.

**Thermal Stability**

Performs reliably in temperatures up to 530°C, suitable for high-pressure hydraulic systems.
