Environment limit for safe use of Type 420 was estimated by corrosion data on laboratory performance. Type 420 shows good resistance to CO2 corrosion at elevated temperatures up to 150°C in several percent NaCl solution. From the view point of resistance to sulfide stress corrosion cracking, partial pressure of H2S is limited to 0.1 atm.. This paper summarizes a lot of kinds of laboratory data for CO2 corrosion resistance at high temperature and SSC resistance at low temperature of L-80 grade Type 420.
