Grain Integrity. Corrosion Resistance. No Shortcuts.

In Marine and Medical applications, grain growth and carbide precipitation cause premature failure. Precise thermal control during forging prevents both. We maintain documented temperature cycles for 304, 316L, and Duplex grades.

20 years of stainless steel forging. Same process. Same documentation. Same result.

Technical Capabilities

Technical Capabilities

🔬

Thermal Control

Documented temperature cycles for 304, 316L, and Duplex grades. Prevents carbide precipitation and grain growth — the primary failure mode in corrosive environments.

🧪

Passivation & Electropolishing

In-house post-forge surface treatment. Passivation restores the chromium oxide layer. Electropolishing removes micro-crevices where corrosion starts.

📋

Material Traceability

Heat lot tracked from mill certificate to finished part. Every shipment: spectrometer report, hardness test, dimensional inspection record.

⚙️

In-House CNC Machining

Raw forged blanks to finish-machined parts. ±0.01mm on critical bore diameters. No secondary supplier.

20 Years. Marine. Medical. Fluid Control.

Our forged 316L SS components have been specified by tier-1 OEMs for over 20 years. Our parts run in offshore marine platforms and sterile medical gas delivery systems.

  • Full material traceability — heat lot tracking from mill to shipment
  • Passivation and electropolishing in-house — no outsourcing
  • 100% dimensional inspection with CMM on critical features
  • Material Test Reports (MTR) included with every order
"In fluid control, a forging that fails costs ten times its purchase price in downtime and liability. We need a supplier who reads a blueprint correctly the first time — and delivers to spec, every time."
