Steel alloy 4130 (ST4130), also known as Chrome Moly is a general-purpose alloy steel widely used by the aviation and motorsports industries due to its tensile strength, weldability, fabrication, and hardenability. Sourced from quality producers AVIATIONEU NEW ERA 4130 Alloy Steel welded round tubes are cold drawn, offered in Normalized (N) condition and can be used in mechanical engineering, automotive applications and machinery. They conform to ASTM A513 specifications and they are offered in different wall thicknesses (1-12.5 mm), outer diameters (OD 6-350 mm) and cut to order lengths (max12000 mm/12 m), in various heat treatment processes (no final thermal treatment, stress relieved, annealed or normalized). Unit of sale is 1 Ton (US or Metric as specified) with Minimum Order Quantity (MOQ) 3 Tons. Sea/sea-surface transport to customer destination can be provided. Approximate time for shipping: usually 1-2 months from the time of order payment depending on the ordered quantity. Appearing price is indicative per unit of sale. Mechanical properties, depending on the selected heat treatment process, are summarized below. For additional information please refer to the attached chart or contact us.
