A chrome plating on these rods increases their corrosion resistance. They're also hardened, which makes them more resistant to impacts and abrasion.

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.

Also known as chrome steel, 52100 is an extremely hard and wear-resistant material. These balls are often used in bearings.
