The Industry Challenge
The Engineering Challenges We Solve.
In Marine, Medical, and Chemical Process environments, material failure is not an option. These are the three specific failure modes our clients face — and how our grain-flow controlled forging process eliminates them.
Chloride-Induced Stress Corrosion Cracking
304 SS fails in saltwater and chlorinated environments. Marine and offshore applications require 316L with verified Mo content (2.0–2.5%). We confirm Mo by OES spectrometer on every heat.
Grain Growth from Uncontrolled Forging Temperature
Forging above 1,200°C causes austenite grain growth. Result: reduced Charpy impact toughness and failed incoming inspection. Our furnaces hold ±15°C. Grain size verified by macro-etch.
Surface Iron Contamination for Medical Use
Free iron from tooling contact causes rust on 316L surfaces. Medical and food-grade applications require passivation per ASTM A967. We provide the passivation cert with every shipment.
Our Promise
Our Engineering Promise.
Stop worrying about intergranular corrosion and structural fatigue. We deliver grain-flow controlled stainless forgings (304/316L) that exceed ASTM standards. Whether it’s marine valves or energy fittings, our parts are engineered to survive where others fail.
Every stainless part ships with material cert, dimensional report, and surface treatment certificate.
OES spectrometer confirms Mo, Ni, and Cr content on every heat. No alloy substitution. Mill certs included with every shipment.
Forging temperature held within ±15°C. Prevents grain growth. Charpy impact values maintained per ASTM A182. Heat treatment records available.
Passivation per ASTM A967. Ra ≤ 0.4μm on sealing surfaces. Certified for Medical, Pharmaceutical, and Food-Grade applications.
