4130, also known as Chrome Moly (aka chromoly) (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.
