Stainless steel investment casting for marine projects
Characteristic
Engineered to withstand the most challenging marine conditions, our high-performance stainless steel investment castings combine exceptional corrosion resistance with outstanding mechanical properties. Utilizing premium alloys including 316L, Duplex 2205, and Super Austenitic grades, our components offer superior protection against saltwater corrosion, pitting, and stress cracking even in deep-sea applications. We specialize in producing precision castings with complex geometries and tight tolerances (CT4-CT7), significantly reducing post-cast machining requirements while ensuring perfect fit and function. Every casting undergoes rigorous quality control to meet stringent DNV, ASTM A351, and NACE MR0175 standards, guaranteeing reliable performance in critical applications such as subsea valves, pump housings, and offshore structural components. With a proven track record in marine engineering, our castings are designed to deliver uncompromising durability and a service life exceeding 30 years in the harshest seawater environments.


Our precision-engineered castings deliver
unmatched marine performance through innovative metallurgy and vacuum casting
technology. Specialized alloys resist biofouling and microbial corrosion while
maintaining deep-sea impact strength. The 98% density structure ensures
superior fatigue resistance in critical components. Hydrodynamic surface
treatments optimize propeller efficiency, while customizable post-casting
finishes address specific environmental needs. These solutions offer 40% lower
lifecycle costs, maintenance-free submerged operation, and full recyclability -
combining extreme durability with environmental responsibility for demanding
marine applications.
