4130 is a through-hardening, chrominum-molybdenum alloy tubing used extensively in the aircraft, and
anywhere light strong structural tubing is needed. It is resistant to oxidation and scaling and has smooth,
clean
interior and exterior surfaces. 4130 is produced by the cold drawn seamless process from
electric-furnace
processed steel. Applications: The weldability of 4130 is excellent, and therefore it
finds popular utilization
in
aircraft type construction where welding is a requirement. Specifications:
MIL-T-6736, AMS -6360
Revision
(Magnaflux Quality) UNS G41330. 4130 "seamless"
tubing (MIL-T-6736) is
interchangeable with 4130
"welded" tubing (MIL-T-6731).
