Stainless Steel Flange

A: Yes. Every single shipment is backed by an authentic, original EN 10204 3.1 MTC. The certificate provides chemical breakdown details (down to carbon percentages), mechanical values (yield, tensile, elongation), hardness levels, heat treatment logs, and PMI confirmation, completely matching the Heat Number stamped on the flanges.

A: Industrial export protection is standard. Each flange sealing face is thoroughly coated with anti-rust oil and protected with an individual heavy-duty plastic snap-on cap to prevent scratches on the serrated finish. The flanges are then layered with moisture-proof plastic film and packed into heavy, export-approved ISPM-15 fumigation-free plywood boxes or secured on robust pallets.

A: Yes. We routinely manufacture flanges using dual-certified steel billets. For example, our F316/316L flanges satisfy both the higher mechanical strength profiles of standard 316 and the low-carbon grain protection properties (≤0.030\%) of 316L, ensuring your inventory is versatile.

A: Standard size and class flanges (e.g., ASME Class 150/PN16 Slip-on or Blind flanges) utilizing stocked raw billets can be machined and shipped within 20 to 30 days. For custom heavy-duty components, large-diameter forgings, or exotic materials like Super Duplex F53, typical bulk production cycles span 35 to 45 days.

A: Yes, our operations are fully compliant with local industrial environmental laws, emissions standards, and safety certifications. We welcome factory tours, customer audits, or third-party verification visits arranged via our international sales coordinators.
