Size Specifications:

4130 bars are produced in “random lengths” that range between 11 to 13 feet long. Cut pieces available.

4130, also known as Chrome Moly (so named for 2 key elements of its composition, chromium and molybdenum), is a general-purpose alloy steel that has been widely used by the aviation and motorsports industries for years. Weldability, fabrication, and mild hardenability make it a popular choice in all forms – tube, bar, sheet, and plate.

Nearly all of our 4130 bars are produced as “Cold Finished Normalized,” which is also known as “Condition D4”. 4130 bars generally meet several AMS specifications, but the most common are AMS-S-6758 and AMS- 6348, but several others may also apply.
