Abstract

Fracture mechanics tests were conducted on a 2¼Cr-1Mo steel in an environment containing 6% hydrogen sulfide and 94% hydrogen at temperatures up to 727 K (850°F) and pressures to 24.1 MPa (3500 psi). A test chamber and accompanying system were designed to test under monotonically rising, sustained, and cyclic loads. This paper contains a description of the design and operation of the system developed to conduct these tests, along with a brief discussion of testing experience and types of results.
