Barrel is the most important part of artillery weapons. To manufacture the barrels, special and advanced technologies such as GFM method for producing raw materials, high-strength alloy steel by using of specific furnaces, rifling, honing and chamber boring are used in Hadid industries. The barrels are produced by Electro Slay Remelting (ESR) process.
Ingots forge to desired dimension with a reduction followed by homogenization, hardening and tempering treatment and mechanical properties including tensile, impact, and toughness will be studied and also ultrasonic testing will be done to identify any internal flows.
