- Yield Strength: 130,000 psi
- Hardness: Rockwell C32 (Hard)
- Specifications Met: ASTM A108
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. Also known as chrome-moly steel, they are used for a wide range of parts, such as gears, axles, shafts, collets, and die holders. They resist fracturing from repeated stress.
