These rods are hardened for increased abrasion and impact resistance. Also known as chrome-moly steel, 4140 alloy steel resists fracturing from repeated stress.

Often called ETD-150, these rods are made from a modified version of 4140 alloy steel and have been drawn at high temperatures for excellent strength.

The surface of these bars is hardened to increase their resistance to impacts and abrasion. Also known as chrome-moly steel, which is used to create molds, structural supports, and other parts.

A hardened surface makes these hex bars more impact and abrasion resistant than untreated bars. They’re also stress relieved to reduce the chance of warping during machining.

Made from 4130 alloy steel, also known as chrome-moly steel, these rods have low carbon content for good weldability. They’re often used to make gears and bushings.

The diameter of these balls is held to a precise tolerance. They’re made from 52100 alloy steel, also known as chrome steel, which has high levels of carbon and chromium to make them extremely hard and resistant to wear.
