Iron-based heat-resistant cast alloy

摘要

An iron-based heat-resistant cast alloy for high-temperature, high-pressure pipe, consisting essentially of, by weight %, -C 0.10 to 0.16 -1.0 >/= Si > 0 -1.5 >/= Mn > 0 -Cr 17 to 23 -Ni 28 to 35 -Nb 0.3 to 2.0 -0.1 >/= Mo >/= 0 -0.08 >/= N >/= 0 - One or two or more kinds of: -B 0.001 to 0.080 -Ti 0.011 to 0.02 -Ca 0.001 to 0.01 -Ce and/or La 0.001 to 0.01 -Zr 0.01 to 0.10 -Fe balance. -
