...Abstract Abstract After two weeks of operation, a poppet used in a check valve to control fluid flow and with a maximum operating pressure of 24 MPa (3.5 ksi) failed during operation. Specifications required that the part be made of 1213 or 1215 rephosphorized and resulfurized steel. The poppet...
