Triloy is a quenched and tempered, machine-straightened, stress-relieved, and demagnetized alloy bar, widely becoming one of the most utilized alloy steel shafting materials in the industry. Our exclusive composition, special processing, and manufacturing controls ensure that you receive the strongest, most fatigue-resistant and machinable shafting bar available on the market.

Triloy is based on an AISI 4340 Ni-Cr- Mo chemistry. Impact and fatigue resistance are enhanced by chemistry control and the removal of harmful sulfur and phosphorus. The bars are stress relieved after straightening to avoid “shape bounce back” when machining. Each bar is demagnetized to ensure no pickup of metallic dust to ruin bearing surfaces.
