This study was initiated under API sponsorship to explore the use of very high strength OCTG in formations having lower H2S concentrations and/or higher pH and colder temperatures. Samples from four commercial pipes, each supplied by a different producer and spanning a wide range of hardness values and yield strengths, were examined by the double-cantilever-beam (DCB) test for their resistance to sulfide stress cracking in mild environments at room and low temperatures. Testing parameters were developed to accommodate the very wide range of cracking tendencies resulting from the markedly different mechanical properties and chemical conditions, ranging from standard to 1% H2S / 4.5 pH, at both room temperature and 40° F. At the mildest condition average values of sulfide fracture toughness as high as 70.1 and 64.1 ksi-vin. (77.0 and 70.4 MPa-vm) were achieved at room temperature and 40° F, respectively. Extrapolations to high strength levels suggest the possibility of using C-125 tubulars in the mildest conditions.

Today a need for a C125 Sulfide Stress Cracking (SSC) resistant material exists with the development of High Pressure/High Temperature (HP/HT) oil and gas fields.  This paper focuses on the SS resistance of industrial heats.

In a 1998 study, costs for corrosion in USA were estimated to be about 276 billion US-$.  One way to reduce this gigantic amount of money is to use modern stainless steels and nickel alloys with excellent resistance to various forms of corrosion in corrosive environments like seawater, brines, oil and sour gas wells.
