Stainless Steel Rectangular Tube Dies

For ERW tube mill lines, we custom design and manufacture high-precision stainless steel rectangular and square tube dies. Made from premium mold steel, precision machined with CNC technology, and finished to a fine polish, our forming and sizing rolls ensure stable continuous operation while effectively eliminating surface scratches and deformation on finished pipes. We support custom dimensions, in-house technical drawings, and OEM client-provided manufacturing.

Product Overview Our stainless steel rectangular tube forming dies are specifically designed for ERW tube mill lines, enabling the precise rolling and shaping of high-quality rectangular and square pipes. Made with premium mold steel and ultra-precise surface treatment, our roller dies prevent drag marks, scratches, and edge distortion, delivering immaculate surface quality for high-end stainless steel tubing.

Key Features & Technical Advantages

• Premium Tool Steel & Vacuum Heat Treatment: Crafted from superior alloy mold steel (such as Cr12MoV, D2, or SKD11) and processed with vacuum quenching to achieve high hardness, exceptional wear resistance, and high resistance to chipping or cracking during extended production runs.

• Precision CNC Machining & Mirror Polish: High-precision CNC turning and fine mirror surface polishing prevent material galling, effectively eliminating surface scratches and cross-sectional deformation on finished tubes.

• Versatile Customization & Flexible Sourcing: We fully support both standard and custom specifications. We can develop technical drawings tailored to your production needs, manufacture according to customer-supplied CAD files, and select specific steel grades based on project requirements.

• Strict Quality Inspection: Each set of forming and sizing rolls undergoes rigorous coordinate measurement, profile matching, and hardness checks prior to shipment to ensure high dimensional accuracy and easy installation.

• High Stability & Extended Service Life: Optimized roll pass design ensures balanced stress distribution across the breakdown, forming, and sizing stages, guaranteeing extended continuous production uptime.

Applications & Material Specifications

• Tube Shapes: Rectangular pipes, square tubing, and custom structural profiles.

• Tube Materials: Stainless steel (200, 300, 400 series, including 201, 304, 316L), carbon steel, and galvanized steel strip.

• Industry Applications: Architectural handrails, structural framing, decorative hardware, automotive piping, and commercial equipment frames.
