Alloy Steel Rectangular Bar: 0.375 in Thick, ±0.001 in, 1 1/4 in x 36 in Nominal Size (WxL), Mill

Wear-resistant 4142 alloy steel flat bars are medium carbon alloy with chromium to resist wear and corrosion, molybdenum to withstand high temperatures without softening, and boron to increase hardness. They are pre-hardened to enhance strength while remaining machinable and weldable. Typical uses include cams, shafts, gears, axles, sprockets, machining parts, and other components under continual stress.
