The spinning process will lead to changes in the micro-structure and mechanical properties of the materials in different positions of the high-pressure hydrogen storage cylinder, which will show different hydrogen embrittlement resistance in the high-pressure hydrogen environment. In order to fully study the safety of hydrogen storage in large-volume seamless steel cylinders, this chapter associates the influence of the forming process with the deterioration of a high-pressure hydrogen cylinder (≥100 MPa). The anti-hydrogen embrittlement of SA-372 grade J steel at different locations of the formed cylinders was studied experimentally in three cylinders. The hydrogen embrittlement experiments were carried out according to method A of ISO 11114-4:2005. The relationship between tensile strength, microstructure, and hydrogen embrittlement is analyzed, which provides comprehensive and reliable data for the safety of hydrogen storage and transmission.
旋压工艺会导致高压储氢瓶不同位置材料的微观结构和力学性能发生变化，这将使其在高压氢环境中表现出不同的抗氢脆性能。为全面研究大容量无缝钢瓶储氢的安全性，本章将成型工艺的影响与高压气瓶（≥100 MPa）的劣化联系起来。在三个气瓶上对成型气瓶不同位置的SA-372 J级钢的抗氢脆性能进行了实验研究。氢脆试验按照ISO 11114-4:2005的方法A进行。分析了抗拉强度、微观结构与氢脆之间的关系，为储氢和输氢安全提供了全面可靠的数据。
