Hangbo Alloy Group
Shanghai · Est. 2012
Every form we melt, forge, roll and finish — plus the individual alloy grades we stock and produce to order. Manufactured in-house from VIM/ESR melt to final inspection.
These are the six standard forms we produce and stock. Every item is melted in-house by vacuum induction melting (VIM) with electroslag remelting (ESR) or vacuum arc remelting (VAR) where the specification requires it, then processed on our own forging, rolling and drawing lines. Full details of melting, forging and inspection capability are on the facilities page.
Nickel alloy round bar and rod in diameters from 3 mm to 500 mm, hot finished, peeled, ground or polished.
Cold drawn and hot extruded seamless tube to ASTM B163 / B444 / B622 for heat exchangers and process piping.
Hot-rolled and cold-rolled plate and sheet from 0.3 mm to 120 mm, cut to size with full traceability.
Ultra-thin cold-rolled strip from 0.02 mm with tight thickness tolerance for springs, diaphragms and electronics.
Open-die and closed-die forgings — rings, discs, blocks and shaped components from VIM/ESR billet.
MIG and TIG filler wire and coil to AWS A5.14 in ERNiCrMo-3, ERNiCr-3, ERNiCu-7 and more.
Beyond mill forms, we supply forged and machined components to drawing — produced from the same traceable melt stock, with dimensional inspection and PMI verification before dispatch.
Forged and fabricated headers, distribution manifolds and nozzle blocks for HRSG, heater and reactor service.
CNC turned and milled nickel alloy components to customer drawing, from certified bar, plate or forging stock, delivered inspection-ready.
Explosive or roll-bonded nickel alloy cladding on carbon steel backing for vessels, columns and scrubbers at lower cost than solid alloy.
Hot-rolled, annealed and descaled nickel alloy rod in continuous coils, 5.5-20 mm, for drawing, heading and weaving.
Hot rolled and cold drawn square, flat and rectangular nickel alloy bar for machined components, furnace fixtures and welded fabrications.
Cold drawn and hot finished hexagonal nickel alloy bar to ASTM B166, B446 and B160 for fasteners, valve trim and precision machined parts.
Drilled tube sheets, tube support plates and baffles for shell-and-tube heat exchangers, built to ASME VIII Div.1 and TEMA.
Seamless rolled rings to 3000 mm OD in Inconel 625, 718, Hastelloy and Monel for turbine, valve and vessel duty.
Studs, bolts, hex nuts and washers in Inconel 625, 718, Monel and Hastelloy for sour service and marine duty.
Elbows, tees, reducers, caps and stub ends in Inconel, Hastelloy, Monel and Incoloy to ASTM B366.
Forged welding neck, slip-on, socket weld, lap joint, threaded and blind flanges to ASME B16.5 / B16.47.
Each alloy behaves differently in forging, welding and heat treatment. The pages below give composition, mechanical properties and corrosion data so you can shortlist a grade before you ask for a quote.
Niobium-stabilised plate, welded pipe, tube, bar and forged fittings to ASTM B463 / B464 / B468 / B473 for sulfuric acid duty.

Sulphuric acid and pharmaceutical duty. Plate, pipe, tube, bar, forging.
Melting, forging, rolling, drawing, heat treatment and inspection are all carried out in our own plant in Shanghai. A small number of very large or highly specialised fabrications are subcontracted to qualified partners under our quality system, and we tell you when that is the case.
Almost certainly. The list covers our standard production, but we regularly make non-standard sections, composite and clad products, and components machined to customer drawings. Send the drawing and we will confirm feasibility.
EN 10204 3.1 as standard, with chemical analysis, mechanical test results and heat number traceability. EN 10204 3.2 with third-party witness (BV, SGS, TUV, DNV, Lloyd's Register) is available, along with NACE MR0175 / ISO 15156 compliance for sour service. See our certifications.
