1144 Round Bar: Material Profile
Elevated manganese and sulfur give 1144 good strength in the as-rolled or cold-drawn condition.
Its chip control and cutting performance suit high-volume turned parts and detailed geometry.
Purchase to the controlling ASTM, SAE, AMS, or customer specification. Section size, supply condition, mechanical properties, surface limits, testing, and heat/lot traceability can change the acceptable material and processing route.
