g Some commonly used plain carbon steels are AISI 1010, 1018, 1040, and alloy steels 4130, 4340. Research these steels and provide a comparative summary of their characteristics, focusing on aspects that make each one unique for certain types of application. Product application guides provided on the internet by steel manufacturers and distributors are one source of information. 2. Write a summary of sections 2-16, 2-17, 2-18, 2-19, 2-20, 2-21.
