of metallurgical innovation and maritime expertise
for extended subsea deployments
to withstand extreme hydrostatic pressures
Carpenter Technology provides the specialized alloys required for the next generation of naval superiority. From deep-sea exploration and submarine components to high-performance surface vessels, our materials are engineered to survive the most corrosive environments on Earth. We partner with defense contractors to deliver alloys that offer the perfect balance of strength, toughness, and long-term resistance to stress corrosion cracking (SCC) and pitting.
Deep-sea environments subject materials to immense hydrostatic pressure. Our high-yield alloys are designed for structural integrity and fatigue resistance in critical pressure hull penetrations and internal systems.
FEATURED PRODUCTS:
718 Alloy: A high-strength, corrosion-resistant nickel-base alloy with excellent weldability for cryogenic and high-temperature service.
Custom 450® Stainless: A martensitic age-hardenable stainless steel with very good corrosion resistance and high strength.
Naval propulsion systems require materials that can handle high torque while resisting the relentless corrosive effects of seawater and cavitation. Our alloys ensure mission-critical reliability for drive shafts and propulsor components.
FEATURED PRODUCTS:
CarTech® Monel® 400 & K-500: Nickel-copper alloys combining excellent corrosion resistance with high strength and hardness.
Custom 465® Stainless: Provides an unprecedented combination of high strength and superior resistance to stress corrosion cracking.
On the open sea, a single failing bolt can lead to catastrophic system downtime. We provide high-performance fasteners designed for high-vibration, high-load maritime applications.
FEATURED PRODUCTS:
MP35N®: A nickel-cobalt base alloy with a unique combination of ultra-high strength, toughness, and exemplary corrosion resistance in seawater.
625 Alloy: Excellent strength and toughness from cryogenic temperatures to 1800°F with high resistance to pitting and crevice corrosion.
Advanced sonar and surveillance equipment require non-magnetic materials that offer high protection for sensitive electronics in deep-water environments.
FEATURED PRODUCTS:
718 Alloy: A high-strength, corrosion-resistant nickel-base alloy with excellent weldability for cryogenic and high-temperature service.
Custom 450® Stainless: A martensitic age-hardenable stainless steel with very good corrosion resistance and high strength.
Our alloys are designed to minimize maintenance intervals and maximize
High-yield materials allow for deeper operating depths and more durable submersible designs.
Specialized chemistries prevent pitting and crevice corrosion even in stagnant or warm seawater.
We offer bar, wire, and strip in various conditions to streamline the manufacturing of complex naval geometries.
