We forge, machine and test nickel alloys, duplex stainless, super austenitic stainless and titanium into flanges, fittings, pipe and custom forgings — with a mill certificate behind every heat.
Forged in Shanghai
Nickel-based, iron–nickel, titanium and super austenitic grades held or sourced against the UNS number you specify.

Specifications
Anyone can quote a grade. The difference is whether the certificate, the heat number and the part in the crate agree — and whether you find out before or after installation.
We buy to the UNS number, not to a trade name. Chemistry, grain size and heat treatment are checked against the mill certificate before the billet reaches the hammer.
Flanges and fittings are forged so the grain flow follows the part. No shrinkage porosity in the pressure boundary, and Charpy and tensile results that hold at low temperature.
Optical emission spectrometry, carbon–sulphur analysis, tensile and impact testing, hardness and metallography are carried out on site, so a non-conformance is found before shipment, not at your site.
EN 10204 3.1 mill certificates, dimensional and PMI reports, heat-number mapping and packing lists are issued as standard — with third-party witness at SGS, BV or TUV when the project asks for it.
Wet sour gas, produced water and amine service call for C-276, 625 and duplex flanges with NACE MR0175 compliance.
Hydrocrackers, reformers and acid-plant lines: 800H/HT, 625, 254SMO and alloy 20 fittings where chlorides and high temperature meet.
Sulphuric, hydrochloric and phosphoric acid circuits, including HF alkylation where Monel 400 and Hastelloy B-2/B-3 are the specified grades.
Superheater and reheat piping, flue-gas desulphurisation and nuclear auxiliary systems, with full heat traceability and third-party witness.
Seawater intake, brine and cooling systems in 2205, 2507, 254SMO and titanium — grades chosen for chloride pitting and crevice resistance.
Sanitary tube and fittings with Ra ≤ 0.
Our laboratory verifies every incoming heat and every finished alloy part. The documents travel with the goods, not after them.
