Alloy Steel Round Bar 4130

Alloy Steel Round Bar 4130 is a round shaped bar of chromium molybdenum 4130 alloy steel.

Alloy 4130 is a widely used Aircraft Steel due to its weldability, ease of fabrication and mild harden ability.

Alloy 4130 is also vacuum degassed to meet the magnetic particle inspection standards of AMS 2301.
