Induction Hardening and Rolled Threads

Induction hardening strengthens packing areas

During manufacturing, the packing area of the rod undergoes induction hardening. This process increases surface hardness to a specified depth without disturbing the integrity of the core material. As a result, rods are stronger, more durable and more resistant to scarring and scuffing.

Induction hardening also eliminates the possibility of flaking, which is common with coated rods.

Rolled Threads Resist Fatigue Cracks

Ordinary rods are made with machined threads. However, machining cuts across internal stress lines and the grain structure of the metal, creating weak points that are subject to fatigue cracking.

Our compressor rods are manufactured with rolled threads. Rolling cold forms the threads using the compressive force applied between two dies. This reshapes internal stress lines and the grain structure of the material, increasing fatigue strength and substantially reducing the risk of cracks.
