Alloy Steel Round Bar 4340

Alloy Steel Round Bar 4340 is a round shaped bar of 4340 Alloy Steel.

This steel can obtain much deeper harden-ability than 4100 series steel. High strength in heavy sections is possible with maximum toughness and ductility.

This material has a high fatigue/tensile ratio and maintains strength, ductility, and toughness at relatively high temperatures.

It also has excellent non-distorting properties for an alloy steel.
