Forgings for defense and naval hardware
Defense components carry shock, pressure and consequence. MTS forges military, naval and armament hardware — including parts destined for shipboard and submarine service — with material sourcing and documentation kept ready for demanding programs.
How MTS forging serves defense
Defense hardware lives under load — impact, vibration and pressure that punish weak metallurgy. Forging answers that with aligned grain flow and a dense, void-free structure that resists fatigue and fracture far better than cast or bar-stock parts. For naval and submarine service, where corrosion and pressure add to the demands, forged components in the right alloy are the durable choice.
MTS forges to print and keeps sourcing disciplined and documented, with DFARS-minded material procurement available for programs that require it. With forging, heat treatment and rough machining under one roof, we shorten the supply chain on components where provenance and consistency matter.
Components we forge for defense
- Naval and shipboard structural components
- Submarine-service hardware in corrosion-resistant alloys
- Armament and weapon-system forgings
- Forged rings and cylinders for housings and mounts
- High-strength fittings, clevises and lugs
- Upset and close-die forgings for shafted and pinned parts
Materials & standards
We forge carbon, alloy and stainless grades — including duplex and nickel alloys for corrosive marine environments — and document them for program traceability.
DFARS-minded sourcing
Material procurement can be kept disciplined and documented to support programs with domestic-sourcing requirements.
Full traceability
Heat numbers and mill test reports follow every order, giving a documented chain of custody for critical parts.
ISO 9001:2015
Parts are produced under our registered quality management system (QAS International, Certificate No. US5024).
