Steel alloy 4130 (ST4130), also known as Chrome Moly after the 2 key alloying elements, chromium, and 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, sheets and plates).
4130 alloy steel sheets are offered as part of AVIATIONEU NEW ERA product lines for a wide range of uses including structural applications, including gears, fasteners, and and aircraft exteriors. These sheets offer good weldability without compromising steel abrasion and impact resistance and can be made even stronger throough heat treatment.AVIATIONEU NEW ERA 4130 alloy steel sheets undergo a heat treating process and they are available in two different material states, Normalized or Annealed, depending on the process of how the material is heated and cooled. The letters "NRZ" and "ANL" specify respectively Normalized or Annealed state in our Reference Codes (SKUs) for ordering of materials. 4130 Annealed steel sheets are produced to the aerospace specification AMS-6350 (sometimes referred to as "Condition A") while Normalized ones meet aerospace specification AMS-6345 (also known as "Condition N"). Annealed steel sheets are "softer" than their normalized steel counterparts and offer higher workability. Normalized steel sheets offer a higher strength tolerance.
Sourced from quality producers, these sheets are offered in different thicknesses and specific widths and lengths in inches. For additional information, please refer to our supplied documentation, the individual product presentations or contact us for quotation.
