Luke Steel, a well-known producer and supplier of Carbon Steel EN-9 Bars with headquarters in Houston, Houstan, offers premium steel products made to satisfy exacting industrial requirements. Luke Steel, which is well-known for its accuracy, robustness, and prompt service, provides EN-9 bars that meet both domestic and international quality standards. High-strength medium carbon steel EN-9 is renowned for its superior mechanical performance and resistance to wear. Components needing greater hardness and load-bearing capacity frequently use it. Luke Steel is the preferred supplier of Carbon Steel EN-9 Bars for a variety of industries due to its robust distribution network and dedication to quality.
With trace amounts of silicon, sulphur, and phosphorus, carbon (0.50–0.60%) and manganese (0.60–0.90%) make up the majority of carbon steel EN-9 bars. Depending on heat treatment, this medium carbon steel has a high tensile strength of 600–800 MPa and a yield strength of 480 MPa. EN-9’s durability and resistance to wear can be improved by tempering and hardening it. It is appropriate for parts needing more surface hardness and strength because it offers good machinability and moderate toughness. Because of its mechanical profile, steel is a great material for heavy-duty mechanical parts.

Carbon steel EN-9 bars are frequently used in the production of parts that require a high degree of durability, strength, and resistance to wear. Gears, shafts, crankshafts, pins, keys, and spindles are among the common parts used in the heavy machinery and automotive industries. Additionally, EN-9 is utilised in agricultural machinery, railroads, and construction equipment for parts subjected to constant stress and friction. It is perfect for applications where improved surface hardness and performance are crucial because of its heat treatment capability. For precision-engineered parts in both static and dynamic load-bearing environments, EN-9 is a material of choice due to its strong mechanical qualities.
