           Solutions based onin-depth analysis of in-field failures
           of base-materials and partsconsidering its applied
       • Development and Supply of Material DB: Material DB
           development andsupply for mechanical design and
           material selection (Microstructure/Chemical composit-
           ion/Mechanical properties(Tensile/Hardness/Impact
           testing) and Fatigue/Creep)

      Corrosion evaluation technology for materials & parts

       • Equipment and technology to evaluate various
           corrosion phenomena suchas salt spray, pitting, crevice,
           electrochemical reaction, gas corrosion and soil
           environment test, etc
       • Supporting for effective anti-corrosion measures by
           evaluating thecorrosion testing
       • Providing reliable test evaluation service by acquiring
           KOLAS certification of standards and evaluating the life
           of materials & parts through corrosion acceleration test

      Standard material production and evaluation technology

       • Standard material: A material with sufficiently homo-
           geneous and well-established property values used to
           calibrate the device, evaluate themeasurement method
       • Designated as the first domestic standard production
           organization in themetal field
       • Developed 18 types of certified standard materials and
           83 types ofprocess quality assurance standards based
           on related infrastructure

      Trace elemental analysis

       • Quantitative analysis of major, minor and trace
           elements in various materials such as silica, alumina,
           silicon carbide, and high purity metalsby ICP-MS
       • Trace elemental microanalysis by Laser Ablation ICP-MS
            and LIBS
       • Impurity analysis in high purity materials by GD-MS

      Laser Induced Breakdown Spectroscopy

       • Laser induced breakdown spectroscopy (LIBS) could be
           applied forelemental analysis in various samples
       • RIST have developed the LIBS system called ROSA (RIST
           Optical Spectroscopic Analyzer) REI-266 for elemental
           mapping in steel industry.
           REI-266 is fast and quantitative analysis LIBS system

      The Characterization Technic for the Secondary Batteries

       • The service of in-situ analysis to be able to observe the
           phenomena onsurface/interface during the cycle test
           and to analyze the LIB materials in air non-exposure
       • The analysis service of mechanism and degradation to
           interpret thereasons for high performance batteries
           (The Failure Analysis for LIBmaterials)

      Analysis and Characterization of Steel

       • Research on the analysis and assessment of steel for the
           technical competitive strength and the products of high
           quality in POSCO
       • Microstructural characterization on high strength steel
           for automobile, galvanized steel for high corrosion
           resistance steel, and electrical steel
       • Development of technologies for the quality improve-
           ment of the analyticaldata on steel

      AI-based steel microstructure automatic analysis technology

       • By using deep learning technology for quantitative
           analysis of microstructure, which is essential for
           the analysis of the relationship between the
           manufacturing process of steel materials and
           physicalproperties, it is easy to obtain a statistical
           representative value by analyzing multiple images
           faster than the existing analysis method.
           In addition, image recognition through pattern
           recognition makes it possible to automatically
           analyze even SEM images that were difficult to
           distinguish just with colors and brightness.
