Hemi Metals, located in Hamilton, New Zealand, has built a solid reputation as a reliable manufacturer and supplier of 1140 Steel Bars and Rods. These products are celebrated for their outstanding machinability, strength, and dependability in various engineering applications. Committed to delivering high-quality carbon steel products, Hemi Metals ensures that every 1140 steel bar and rod meets strict quality standards for dimensional accuracy and mechanical stability. These bars and rods find their way into the hands of fabricators, OEMs, and industrial sectors that need medium-carbon steel known for its wear resistance, heat-treatability, and consistent performance in machining, forging, and structural tasks.
When it comes to composition and mechanical properties, 1140 Steel Bars and Rods are medium-carbon steels with about 0.37–0.44% carbon, 0.60–0.90% manganese, along with trace amounts of sulfur, phosphorus, and silicon. The inclusion of sulfur boosts machinability, making 1140 a great choice for high-speed machining tasks. In terms of mechanics, 1140 steel offers good tensile strength, moderate hardness, and enhanced wear resistance after heat treatment. It boasts strong machinability, decent ductility, and reliable toughness, making it suitable for general engineering components. When quenched and tempered, it gains increased strength, perfect for parts that face mechanical stress.
