What are the correct materials for a screw and a threaded plate for hydrogen sulfide environment per NACE. Temperature and pressure do not matter, nor does any significant load or torque. Thanks, Kenneth

Kenneth: NACE MR0175 RP has been replaced by ISO15156. Material's selection criteria is a little more involved than in the old MR0175, as recommended material selection is dependent on H2S partial pressures, temperatures, chloride content, heat treatment, etc. We recommend that you purchase a copy of ISO15156 from the NACE bookstore at http://www.nace.org.
