We are a leading stockholder and global supplier of metals and plastics into Aerospace & Space, Chemical, Defence, Medical, MRO, Naval, Nuclear, Oil & Gas and Power industries.
We make high quality materials available in a fast, cost-effective and convenient package and provide a consistent supply path for all our customers.
We stock 4140 steel bars, a deep hardening steel that is tough and fatigue resistant.
Alloy 4140 provides high fatigue strength making the product suitable for critically stressed components at normal and elevated temperatures. Good overall strength and impact toughness are also performance benefits. Overall machinability of the alloy is good in the annealed condition. Uniform hardness and high strength are achieved due to the introduction of molybdenum, while chromium provides good hardness characteristics. Alloy 4140 also offers good ductility.
We stock 4140 steel bars in a wide range of sizes and conditions (including annealed, normalised, hardened and tempered conditions).
