Tank Turret Trunnion Pins

The Tank Turret Trunnion Pin is forged from low-alloy, high-strength steels with controlled composition to achieve an optimal balance between hardness, ductility, and fatigue resistance. Quenching and tempering cycles are precisely controlled to produce a martensitic microstructure with uniform hardness typically ranging from 55 to 62 HRC. Secondary treatments such as sub-zero processing reduce retained austenite, improving dimensional stability.
