Material degradation diagnosis technology, material testing technology, environmental analysis, certification services.

Based on the technical skills and know-how cultivated over 100 years of history since our founding, we respond to customer requests for material degradation and damage investigations, various tests, and on-site inspections.

● Material Degradation Diagnosis Technology - Material degradation and remaining life assessment of long-term use equipment - Diagnosis of material and defect characteristics of operating components - On-site metal microstructure observation using the replica method (SUMP) (boiler tubes, turbines, valves, heating furnaces, reaction devices, etc.) - Investigation and analysis of the causes of failure in damaged components ● Material Testing Technology - Tensile tests, impact tests, bending tests, hardness tests, fatigue tests, creep tests, fracture toughness tests, etc. ● Analytical Investigation Technology - Material analysis, environmental analysis ● Measurement Instrument Calibration Services *Due to company integration, Nikkō Inspection Service Co., Ltd. has changed its name to Nippon Steel Engineering Co., Ltd.
