9%Cr-1%Mo consumables designed
for prolonged elevated temperature
service up to about 600°C, especially
in superheated steam, hot hydrogen
gas and high sulphur crude oil.
Used
for pressure vessel, heat exchanger
and piping in oil & gas industries and
power plant. The alloy is an air-hardening material and, therefore, when welding with this filler metal, preheat
and postweld heat treatment are required.
