Sintered Materials on the base of Iron with Special Regard to Alloyed Sintered Steels

The production of ` parts " of all kinds produced of sintered iron, sintered carbon steel or alloyed sintered steel is a kind of mass production which is becoming
of increasing importance in industrial countries since the end of World War II 1,2 In Europe about 3000 tons of sintered parts were produced during 1954 and the production
of such parts in the United States is a multiple of the above-mentioned figure.What are the reasons for powder metallurgy to prevail in spite of the highly developed
methods of the industries producing or processing
iron ? Three reasons are of importance:
(1) The utilization of the porosity and
Plasticity of sintered iron opened new
fields of application not obtained with
other procedures.
(2) Sintered material with very valuable
Physical and chemical properties can be
produced by powder metallurgy.
(3) The cheaper sintering process is used
for technical and economical reasons.
