Wanfang Steel Group Co., Limited supplies 40Cr alloy steel bar, equivalent to AISI 5140, a chromium-alloy steel widely used in machinery manufacturing, automotive components and gear production. The product is available in hot rolled, forged or cold drawn conditions, offering flexibility for different industrial applications. Its chromium content improves hardenability, while the medium-carbon level provides a balance of strength and machinability.
This grade delivers excellent tensile strength and wear resistance, making it suitable for gears, shafts and structural components in heavy machinery, aerospace and automotive industries. The material’s versatility allows for various surface hardening treatments, including high-frequency and flame hardening, to meet specific performance requirements. Standard diameters and lengths accommodate OEM and fabrication needs for global trade.
Industrial buyers source 40Cr alloy steel bar for applications requiring high strength, toughness and fatigue resistance. The material is traded in bulk quantities, with dimensions tailored to precision machining processes such as CNC. Importers should confirm the delivery condition, heat treatment status and packaging to ensure compatibility with their production workflows. The grade’s consistent properties make it a reliable choice for export markets.
