Technical Specifications
Advanced Metallurgy for Tough Alloys
The manufacturing of stainless steel finned tubes requires tools that can handle extreme pressure without deforming. Nexmek rolling blades are crafted from ultra-tough tool steels that maintain their edge even under the high-torque conditions required for SS 304/316 extrusion.
- Specialized heat treatment for maximum fracture toughness under work-hardening
- Micro-polished edges to prevent micro-fractures in SS fin roots
- Engineered to reduce the 'spring-back' effect in SS 316L & Duplex alloys
Precision Fin Geometry & Standards
Our blades are compatible with standard and custom finning machines, allowing for a wide range of fin configurations tailored to specific industrial requirements.
| Parameter | Stainless Steel Capability Range | Tolerance & Standard |
|---|---|---|
