Characteristics of metal such as strength, toughness, and ductility which make metals useful. The properties which govern the design and service behavior of the weldment are the following:
(1) Modulus of elasticity
(2) Elastic limit
(3) Yield strength
(4) Tensile strength
(5)Fatigue strength
(6) Ductility
(7) Fracture toughness
(8) Low temperature properties
(9) Elevated temperature properties
