ASTM A519 AISI 4130 Alloy Steel Seamless Round Tube 14x4 14x4.5 Cold Drawn Steel Tube
4130 Steel Introduce
AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents.
The steel has good strength and toughness, weldability and machinability.
AISI/SAE 4130 grade is a versatile alloy with good atmospheric corrosion resistance and reasonable strength.
It shows good overall combinations of strength, toughness. and fatigue strength.
4130 Steel Applications
This low-alloy steel finds many applications
-as forgings in the aerospace and oil and gas industries.
-as forged valve bodies and pumps.
-as well as in the automotive, agricultural and defense industries.
