Carbon steel is a metal alloy of carbon and steel. There are four types of carbon steels, ranging from low to very high, that are classified by the amount of carbon they contain. Carbon steel forgings exhibit strength, hardness, ductility, and impact resistance.

This project aims at organic pure substances by setting up an organic pure material valuation technology system and an uncertainty assessment model covering the purity measurement of organic molecules of different molecular weights such as small molecules, macromolecules, and C peptides, and developing organic first-class reference materials for pure substances 20 For high-purity metals, a purity measurement method for depletion of high-purity metal all-impurity elements and an uncertainty evaluation model have been created. Two high-purity metal purity national standard materials have been developed; for high-purity gases, ultra-high purity gases have been used. The development of standard generation systems and the establishment of high-accuracy analysis methods have resulted in the development of six high-purity and ultra-high-purity gases, national first-class reference materials for nitrogen, argon, and helium; and for isotope measurement, high accuracy HR-ICP has been established. -MS measurement technology, the measurement uncertainty of 28Si molar mass reached 1×10-8, and achieved international equivalence; a molybdenum isotope absolute mass spectrometry technology based on the full calibration mechanism was established, and the isotope composition of six natural molybdenum samples was completed. Atomic weight measurement, the uncertainty is one order of magnitude lower than the current international standard value.
The project aims at the development of new materials, food safety, clinical inspections, biomedicine, and environmental monitoring. It addresses the new needs for high-accuracy chemical metrology traceability technologies, conquering high-accuracy nuclear magnetic resonance quantitative techniques, mass balance techniques, and high-purity metal purity determination. Key technologies such as value technology, high-purity gas purification and preparation techniques, isotope mass offset correction and other common key technologies have established a relatively complete traceability technology system covering high-purity organic, high-purity inorganic, high-purity gases, and isotope and other high-accuracy measurements; Developed a batch of traceable sources of typical high-purity national-based reference materials, providing traceable support for the accurate measurement of pure material purity in China; conducted international cooperation research through leading and participating in international comparisons to achieve material purity and isotope abundance in China. The international equivalence and international mutual recognition in the high degree of accuracy measurement have enhanced China's international influence and discourse power in the international measurement industry and other related fields.
