	%X The objective of this project is to study the corrosion
behaviour and hardness based on the presence of martensite in dual
phase steel. This study was conducted on six samples of dual phase
steel which have different percentage of martensite. A total of 9
specimens were prepared by intercritical annealing process to study
the effect of temperature to the formation of martensite. The low
carbon steels specimens were heated for 25 minutes in a specified
temperature ranging from 7250C to 8250C followed by rapid cooling
in water. The measurement of corrosion rate was done by using
extrapolation tafel method, while potentiostat was used to control and
measured the current produced. This measurement is performed
through a system named CMS105. The result shows that a specimen
with higher percentage of martensite is likely to corrode faster.
Hardness test for each specimen was conducted to compare its
hardness with low carbon steel. The results obtained indicate that the
specimen hardness is proportional to the amount of martensite in dual
phase steel.
