Rupture Behavior

The creep and rupture properties of steels were investigated at 1000 deg F in an environment of argon at 50 psig pressure and hydrogen at 900 psig pressure. An SAE 1020 steel, a 0.5 percent Mo-steel, and a 1 percent Cr-0.5 percent Mo steel were used as test materials. The strength of the steels was lower and the creep rate higher in hydrogen than in argon. The data are discussed in respect to the effect of stress on the rate of hydrogen attack.

Abstract Hydrogen storage cylinders are often used for medium- and short-distance transportation of hydrogen. The presence of hydrogen tends to increase the risk of using the gas cylinders. The alternating stress caused by factors such as hydrogen charging and discharging during the service process of the gas cylinder leads to the expansion of initial cracks inside the cylinder and the final fatigue fracture. At present, the fatigue life calculation of pressure vessels mainly adopts the S-N curve method, however, some steels do not have the S-N curve under the hydrogen environment, it is necessary to use fracture mechanics methods to analyze the fatigue life of gas cylinders in a high-pressure gaseous hydrogen environment. In this work, a method for calculating the fatigue life of fracture mechanics for hydrogen storage cylinders was established according to ASME VIII-3 KD-10. The development of the program was completed by Matlab. An example was given to illustrate the program. Firstly, basic parameters of the material used for the cylinder were obtained. Then, finite element method was used for stress analysis to obtain the fitting curve and the function expression of hoop stress. Finally, fatigue life calculations of high pressure hydrogen storage cylinder were made. The minimum service life of example was predicted to be 40 years. This result is consistent with the good service history of this type of container. This work could contribute to design, safety evaluation of hydrogen storage cylinders.

In Japan, with regards to the widespread commercialization of 70 MPa-class hydrogen refueling stations and fuel cell vehicles, two national projects have been promoted on both the infrastructure and the automobile sides. These projects have been promoted to establish the criteria for determining hydrogen compatibility of materials and to expand the usable materials for high-pressure hydrogen environment. For these projects, establishing test methods to evaluate the hydrogen compatibility of materials is one of the most important tasks. This paper describes the status of common standardization of testing methods. Two projects share a common database for the testing results, which is currently put to practical use.
