AISI 4340
We could produce AISI 4340 forging parts,AISI 4340 forged rings, AISI 4340 Rolled Rings,AISI 4340 forging flanges, AISI 4340 forging round bars, AISI 4340 forged disks, AISI 4340 forging gears, AISI 4340 forging shafts , AISI 4340 forging pipes as per the requirement of the clients
AISI 4340 is a heat treatable and low alloy steel containing chromium, nickel and molybdenum. It has high toughness and strength in the heat treated condition.
We could delivery AISI 4340 forging material as per the standard of ASTM A29/A29M-91
We use EAF + LF + VD melting methods to melt the material of AISI 4340
As per heat treatment of AISI 4340 forged parts, We could do anealed, normalized, hardening and tempering as per the needs of the clients.
The chemical composition of AISI 4340 is as follows:
The mechanical property of AISI 4340 is as follows:
