Abstract
Materials selection. The choice of materials is a sorted one is the process by which engineers remove one or a small number of items that can be found most suitable. Successful engineering design material selection is critical to the process. As much as possible your preparation must be strong and durable that’s what you want. Security to consider there are also implications. You see, with poor material, there are many more dangerous failures arising from examination a very common occurrence in industries. The weighted product method is a multi-criteria decision-making process there are many alternatives, and based on several criteria we must determine the best alternative. Alternative: Specific strength (Mpa), Specific modulus (Gpa), Corrosion resistance, Cost category. Evaluation Preference: AISI 1020, AISI 1040, ASTM A242, AISI 4130, AISI 316. From the result, it is seen that AISI 4130 is got the first rank whereas is ASTM A242 is having the lowest rank. As a result, AISI 4130 is ranked first, while ASTM A242 is ranked lowest.
