XTD Special Steel production plant — affiliated mill of Xinzhe

Who we are

Wenzhou Xinzhe Tech Co., Ltd. is a China-based stockist and exporter of seamless stainless steel, duplex, super duplex and nickel alloy pipe and tube, founded in 2019 in Wenzhou, Zhejiang.

Backed by our affiliated mill, Zhejiang Xintongda Special Steel Manufacturing Co., Ltd. (XTD Special Steel), we combine the responsiveness of a stockist with the production control, traceability and cost advantage of a direct manufacturer.

Dual-structure advantage: immediate availability in standard sizes and grades, plus direct mill production for special specifications, non-standard dimensions and project orders — without the mark-ups and lead-time uncertainty of pure trading companies.

The industrial capacity behind the stock

Because Xinzhe's supply is supported by the XTD Special Steel plant, every order carries full production traceability — from the material certificate to final testing — instead of relying on third-party purchases with limited visibility. This is the key difference from distributors who resell stock of unknown or mixed origin.

Product range

Seamless stainless steel pipe and tube; duplex and super duplex stainless steel (S31803/S32205, S32750/S32760); nickel alloys: Inconel (600/625/825), Incoloy (800/825/925), Hastelloy (C276/C22), Monel (400) and pure nickel (200/201).

Formats: boiler tubes, heat-exchanger tubes, U-tubes, condenser tubes, and high-pressure heavy-wall pipe for demanding service conditions.

Quality assurance

Every order is delivered with the manufacturer's mill test certificates (MTC) and full production traceability. Quality control is applied at every stage: raw-material inspection, dimensional control, mechanical and corrosion testing, and final inspection. On request, we arrange third-party inspection (SGS, BV or a designated agency) before shipment.
