Hemi Metals, based in Hamilton, New Zealand, has built a solid reputation as a reliable manufacturer and supplier of 1141 Cold Drawn Bars and Rods. These products are celebrated for their exceptional machinability, strength, and smooth surface finish. Committed to quality and precision, Hemi Metals ensures that their 1141 steel bars adhere to industry standards for dimensional accuracy and mechanical consistency. The cold drawing process significantly boosts the material’s tensile strength, straightness, and surface smoothness, making it perfect for high-speed machining and precision components. Customers trust Hemi Metals for reliable, cost-effective medium-carbon steel bars that are ideal for automotive, industrial, and general engineering applications.
1141 Cold Drawn Bar/Rod is a medium-carbon steel that contains around 0.37–0.45% carbon, 1.35–1.65% manganese, along with trace amounts of silicon, phosphorus, and sulfur. The addition of sulfur enhances its machinability, making it a great choice for precision machining. Cold drawing not only improves tensile strength but also boosts yield strength, hardness, and dimensional accuracy. This alloy is known for its good fatigue strength and moderate toughness, ensuring it performs well under mechanical stress. With its superior surface finish and tighter tolerances, 1141 is perfect for high-speed machining, threading, drilling, and forming operations.
