AISI 4130 Alloy Steel
UNS G41300AISI 4130 Alloy Steel
AISI 4130 alloy steel is a chromium-molybdenum alloy steel and is considered a low carbon steel. It is popularly known as Chromoly in the commercial market. AISI 4130 alloy steel properties make it a versatile metal, especially mechanical properties such as high ductility, good weldability, and machinability. AISI 4130 alloy steel is exceptional welding steel, which you can weld by most common methods, and machine it at normalized or tempered conditions. When heat-treated, AISI 4130 alloy steel develops mechanical properties that make it a very strong metal, although it can lose some of its machinability.
Applications for AISI 4130 alloy steel include military aircraft, commercial jets, automotive, machine tools, hydraulics, motor sports, aerospace, and welded tubing (especially in the oil and gas industries).
Product forms include bar, seamless tubing, and plate.
