Steel alloy 4130 (ST4130),aka Chrome Moly,after the 2 key composition elements,chromium & molybdenum,is a general-purpose alloy steel widely used by the aviation and motorsports industries due to its weldability, fabrication and mild hardenability in all offered forms (tubes, bars/rods, sheets and plates). Available in two material states (Normalized and Annealed) depending on the process of how the material is heated and cooled.The Normalized condition (aka "Condition N") is the harder and stronger condition, best used when forming is not needed while the Annealed condition (aka "Condition A") is the softer and formable condition.
4130 steel bars/rods in round, rectangullar (flat), square and hexagonal shapes (cross sections) are offered as part of our own branded (AVIATIONEU NEW ERA) product lines. Sourced from quality producers, most of these bars/rods are produced, unless otherwise specified, as “Cold Finished Normalized” (aka “Condition D4”), indicated by the letters "NRZ" and "CF" in the product SKUs.They are widely used in a variety of applications due to their excellent strength to weight ratio,weldability by all conventional methods and resistance to scaling and oxidation.
AVIATIONEU NEW ERA 4130 Steel Alloy Rectangular (Flat) Bars/Rods are AMS S 6758 Condition D4 (Cold Finished Normalized) and Tempered MIL S 6758, unless otherwise specified. They are offered in different widths, thicknesses and pre-cut lengths in inches. Also available in cut to order lengths (please refer to the respective product presentation). It's best to keep the lengths under 5 feet for air shipping. Longer bars can only be shipped via standard sea/ground transportation.
Unless otherwise mentioned, there is additional cost if manufacturing test reports are required. For additional information, please refer to the supplied documentation, the individual product presentations or contact us.
