S32707 2707HD duplex pipe

SAKY METAL SAF 2707 HD is a high­alloy duplex (austenitic­ferritic) stainless steel for service in highly corrosive conditions. The grade is particularly suited for use in aggressive acidic and chloride containing environments. Seamless tubes in SAF 2707 HD can be supplied in typical heat exchanger tube dimensions. Tubes are generally delivered solution annealed, with a pickled or light ground surface condition.
