Also known as Nitriding 135, this steel can be hardened at lower temperatures than other heat-treatable alloys. Heat treating gives it a wear-resistant surface without making the interior brittle. It’s often used for gears, axles, and shafts. These rods have been manufactured to meet SAE standards for quality and performance.
