- (e) Ti-6A1-4V annealed titanium alloy.
(a)
The tensile and yield strength of the UNS G10200 hot-rolled steel.
Explanation of Solution
The ability of material to withstand pulling force is called as tensile strength. The tensile strength express as the force per unit area.
The amount of stress that causes permanent deformation in the material is called as yield strength. It is the maximum stress after which the material changes their shape. The material deforms permanently after the elastic limit.
Refer to the Table A-20 “Deterministic ASTM Minimum Tensile and Yield Strengths for Some Hot-Rolled (HR) and Cold-Drawn (CD) Steels” to obtain the tensile and yield strength as
Thus, the tensile strength and the yield strength for the UNS G10200 hot-rolled steel is
