Question
A specimen of an AISI-SAE type 416 stainless steel with a 0.505-in. diameter was machined to a 2.00-in.-gage length and the following data were collected:
After fracture, the gage length was 2.75 in. and the diameter was 0.365 in. Plot the After fracture, the gage length was 2.20 in. and the diameter was 0.325 in. Plot the engineering stress strain curve and calculate
(a) the 0.2% offset yield strength;
(b) the tensile strength;
(c) the modulus of elasticity;
(d) the % elongation;
(e) the % reduction in area;
(f) the engineering stress at fracture;
(g) the true stress at necking;
(h) the modulus of resilience; and
(i) the elastic and plastic strain to fracture.
(j) W hen the sample was loaded to 11,400 lbs, the diameter was measured to be 0.504 in. Calculate the tranverse and axial strains at this load. Compute the Poisson’s ratio.
(k) Obtain the tensile properties for type 416 stainless steel that has been quenched and tempered and compare them to your answers. Discuss the similarities and differences.
