316L stainless, naval brass, duplex stainless and engineering plastics — corrosion-grade reproductions for propulsion, deck hardware and engine room components when the part is unavailable or discontinued.
| Application | Material | Why |
|---|---|---|
| Deck hardware, fastenings | 316L stainless | Standard marine grade; resists atmospheric and immersion corrosion |
| Propulsion components, seacocks | Naval brass / HTB1 bronze | Dezincification resistant; traditional marine bronze equivalent |
| Highly loaded fittings, seawater service | Duplex 2205 | Higher strength than 316; superior chloride resistance |
| Extreme chemical or crevice conditions | Super duplex 2507 | PREN >40; suits aggressive marine environments |
| Bearings, bushings, guides | HDPE or Delrin | Self-lubricating, water-resistant, light |
| Cutlass bearings | Nitrile rubber / brass carrier | Reproduced to original interference and bore diameter |
Haul-out deadline. Tell us when the vessel goes back in the water — we work back from that date. A single CNC-machined part in 316L stainless is typically 5–10 working days after approval. We confirm the timeline honestly before you commit.
Include the marine environment: salt water, fresh water, brackish. This determines whether we reproduce in 316L or recommend an upgrade to duplex.
All bore diameters, shaft interfaces, flange patterns, seal grooves and corrosion-critical surfaces measured to ±0.01 mm.
Drawing to your approval with material grade specified. Electropolish or passivation noted where applicable.
Stainless parts passivated post-machining. Bronze and brass components deburred and inspected. Shipped with CMM report.
316L stainless, 304 stainless, naval brass / HTB1 bronze, phosphor bronze, duplex 2205, super duplex 2507, Hastelloy C276 for aggressive environments, HDPE and PTFE for bearing and seal applications.
Yes — propeller shaft seal carriers, cutlass bearing housings, stern gland components and shaft brackets are commonly reproduced items. We measure bore, OD, face run-out, seal groove geometry, and water inlet/drain provisions from the original.
A quote in 24 hours. Production for a single machined component in 316 stainless: typically 5–10 working days after approval. Express turnaround is available — tell us your haul-out deadline and we assess whether we can hit it.
Yes. Phosphor bronze and naval brass (HTB1) are standard materials for propulsion components. We machine shaft keys, taper sleeves, locking nuts, cutlass bearing carriers and custom stern tube fittings in these materials.
