is it possible from the metalorogy view point to make the last seven tubes of the coker heater from a metal which withstand skin temperature in the range of 730C ? We always suffer from high skin temperatures(677C) in the last three tubes(the nearest to the burners) of the heater short times( 30days) after steam spalling.the tubes metal is 9cr.
