With respect to grain size: 1) Is there a threshold grain size that is correlated to passing mechanical properties? And, 2) What is the proper etchant to reveal the 2205 grain size?
Within the range of 1870-2010°F, strength is unaffected by annealing at one end of the range versus the other? Or, would one expect higher strengths and lower ductility by annealing closer to 2010°F and producing a structure with a higher percentage of ferrite?
Is there an optimal solution annealing temperature for dual certified 2205 (UNS S31803/S32205) to achieve the 5 ksi higher strength requirements of S32205 found in ASTM A789 and A815? Several datasheets found on-line indicate that a company's S31803 grade has a typical chemistry that mimics the...
