摘要

#CMT# #/CMT# Exhaust manifold or turbo-supercharger housings for internal combustion engines, comprises whole or a part of iron-aluminum steel alloy composition comprising: 8-23 wt.% of aluminum; 0-5 wt.% of chromium; 0-10 wt.% of one or more elements of carbon, titanium, zirconium or vanadium, where the amount of single element is maximum 2 wt.%; 0-200 ppm of boron; and 0-5 wt.% of niobium, where iron and the production-related impurities is present at a quantity of 100 wt.%, based on the remaining portion of the alloy. #CMT#USE : #/CMT# The exhaust manifold or turbo-supercharger housing is useful in internal combustion engines. #CMT#ADVANTAGE : #/CMT# The exhaust manifold or turbo-supercharger exhibits improved thermal conductivity, high mechanical strength at high temperature, and excellent oxidation resistance. #CMT#INORGANIC CHEMISTRY : #/CMT# Preferred Components: The amount of: aluminum is 15-17 (preferably 16) wt.%; boron is 10-100 ppm; carbon, titanium, zirconium or vanadium is 5 wt.%, where the amount of single element is maximum 1 wt.%.
