We specialize in manufacturing custom sheet metal parts from 6mm 316 stainless steel plate, serving industries where a single-gauge solution must balance structural rigidity with fabrication flexibility. At 6mm thickness, 316 austenitic stainless steel occupies a versatile middle ground: substantial enough to serve as load-bearing brackets, equipment frames, and pressure-rated panels, yet thin enough to be laser-cut, brake-formed, and welded into complex three-dimensional assemblies without the extreme power requirements or thermal warping challenges of heavy plate.
Our production workflow transforms standard 6mm 316 plate into finished components—complete with precision-cut profiles, formed flanges, machined holes, and sanitary welds—delivered ready for direct installation in chemical processing lines, marine equipment, food production facilities, and coastal infrastructure.

Why 6mm 316 Stainless Steel for Custom Parts
Feature
Benefit in 6mm Gauge
Structural Rigidity
Self-supporting across spans up to 1,500mm without secondary framing; ideal for equipment bases and tank standoffs
Pressure Compatibility
6mm wall thickness rated for moderate internal pressures in manifolds, header plates, and vessel flanges
Balanced Heat Input
Laser cuts efficiently with minimal distortion; weld joints require no preheat in ambient conditions
Corrosion Margin
Sufficient material depth to tolerate light pitting in marine atmospheres while maintaining structural integrity
Weight Efficiency
At approximately 47.7 kg/m², 6mm plate provides strength without the handling and transportation penalties of 10mm+ plate
Custom Fabrication Capabilities
Fiber Laser Profiling: High-power nitrogen cutting produces bright, oxide-free edges on 6mm 316 plate, eliminating the need for post-cut grinding before welding or passivation.
CNC Press Brake Forming: Accurate angular forming of trays, chutes, and enclosure bodies with crowning compensation to maintain bend consistency across 4-meter lengths.
Precision Holemaking: Laser-cut holes, slots, and cutouts for bolts, bearings, and sight glasses; post-laser reaming available for H7/H8 press-fit tolerances.
Welded Assembly: Certified TIG welding with 316L filler wire for corrosion-matched joints; back-purging on critical seams to prevent sugaring.
Surface Finishing: In-house pickling and passivation restore the chromium oxide layer on cut and welded edges; electropolishing available for food and pharmaceutical service.
Quality Assurance
Material Verification: XRF spectrometry confirms 16–18% Cr, 10–14% Ni, and 2–3% Mo content, ensuring genuine 316 chemistry and excluding 304 or 201 substitutions.
Thickness Survey: Ultrasonic thickness gauging at multiple points on each plate to confirm full 6.0mm uniformity before cutting.
Dimensional First Article: Full CMM inspection of the first part from each nest, verifying hole positions, flange heights, and overall profile against customer solid models.
Weld Integrity: Visual inspection plus dye penetrant testing (PT) on all pressure-boundary and sanitary welds.
Documentation: Mill test certificates (EN 10204 3.1), inspection reports, and weld logs provided standard; 3.2 certification available upon request.
Packaging & Delivery
Surface Protection: Interleaved with PE foam or kraft paper to prevent abrasion of polished or brushed faces; VCI film wrapping for ocean freight.
Edge & Corner Guards: Plastic or steel protectors on formed and welded assemblies to prevent transit damage to precision edges.
Kit Assembly: Multi-part assemblies bagged and labeled by BOM line item to streamline your on-site installation sequence.
Shipping: Express courier for urgent prototypes; sea or air freight for production volumes. FOB, CIF, DAP, and DDP terms available.
