The HWDP member consists of a tubular member with a longitudinal bore therethrough, and includes connectors or tool joints attached at each distal end for connecting additional HWDP members. The tubular member and tool joints are preheated, water quenched and tempered to obtain a unique combination of hardness, a yield strength and impact strength for improved resistance to stress corrosion cracking and hydrogen embrittlement in a hydrogen sulfide environment.
