“中国高强低温钢1号”的三落三起

Core Viewpoint - The development of "China High Strength Low Temperature Steel No. 1" is a significant advancement in materials used for superconducting magnetic confinement fusion devices, marking a breakthrough in China's pursuit of fusion energy technology [1][15]. Group 1: Material Development - "China High Strength Low Temperature Steel No. 1" is primarily used in superconducting magnetic confinement fusion devices and has achieved mass production after a decade of development [1][15]. - The steel was developed in response to issues faced by the International Thermonuclear Experimental Reactor (ITER), where existing materials failed under extreme conditions [4][5]. - The new steel, designated as CHSN01, surpasses the performance of traditional materials like 316LN, achieving a yield strength of 1500 MPa, which is 500 MPa higher than 316LN [7][15]. Group 2: Research and Collaboration - The development process involved collaboration among various research institutions and enterprises, forming a "High Strength Steel Alliance" to drive innovation and production [12][14]. - The alliance adopted a competitive approach, encouraging open sharing of technology among members to enhance the development of the new steel [13]. - The project received renewed momentum in 2021 when key researchers emphasized the importance of developing advanced low-temperature steel for the BEST project [11][14]. Group 3: Industry Impact - The successful development of CHSN01 is expected to meet the demands of China's next-generation fusion devices, addressing the need for high-performance materials in the nuclear fusion sector [13][15]. - The steel's applications extend beyond superconducting devices, indicating potential uses in other related fields, thus broadening its market impact [15].
