Forged rings and seamless rolled rings
Hubs, housings, sleeves, bushes, and hollow bars
Discs, blocks, and forged plates
Custom forged components including tube sheets, nozzles, valve bodies, and more

Main Applications of Inconel 725 Forgings

Inconel 725 forgings have exceptional corrosion resistance and high strength for critical working conditions, making them first choice material for the following applications:

Oil & gas: forged valves, wellhead equipment, flanges, BOP components, drill pipes, and risers
Power generation: turbine components, compressor parts, reactor pumps, and pressure vessels
Petrochemical: heat exchangers, reactor internals, and high-pressure process equipment
General industry: mechanical seals, pump casings, impellers, shafts, fasteners, and subsea equipment

Application Cases of Inconel 725 Forgings

Case 1: Offshore Oil & Gas Wellhead Components

We produce custom Inconel 725 forgings as per API 6A and 17D standards including forged flanges, valve bodies, and wellhead components for one offshore oil & gas company in the Texas and Louisiana. Our Alloy 725 forgings have exceptional resistance to seawater corrosion, H₂S, and chloride stress corrosion cracking (SCC), and make finished parts that have long lifetime working even in harsh offshore environments.

Case 2: Subsea Valve & Flow Control Equipment

UNS N07725 forgings are widely used in subsea ball valves, gate valves, check valves, and flow control systems. The Inconel 725 forgings that we supply have superior mechanical properties and great corrosion resistance and 100% meet strict international standard ISO 15156/NACE MR0175 for Norway oilfield and subsea equipment.

Case 3: Gas Turbine & Power Generation Components

We manufacture high-quality Alloy 725 forgings such as forged rings, discs, shafts, and turbine components(turbine blades and turbine disks) for gas turbines and power generator. These UNS N07725 forgings exhibit excellent high-temperature stability, creep resistance, and fatigue performance for long time stable operation in power plants.

Quality Assurance & Testing for Inconel 725 Forgings

All our Inconel 725 forgings need to have strict inspection and testing before delivery to meet international standards or clients technical manual:

100% dimensional inspection and visual inspection
Hardness testing and microstructure analysis
Magnetic Particle (MT) or Liquid Penetrant (PT) non-destructive testing
Ultrasonic (UT) or Radiographic (RT) non-destructive testing
Full material test reports (MTR) with EN 10204 3.1 certification
NACE MR0175 / ISO 15156 for sour service applications
