I have been reviewing materials quoted from a variety of suppliers. With my drawing requiring 316L (Free Machining, Annealed 1.5" Bar) I have received certs indicating minimum yield strength of:
25ksi, 29ksi, 36ksi, 40ksi, 42ksi and 45ksi
How can the same 316L material be so different?
Am I not fully specifying the raw material? Are some of these not fully annealed? Are different suppliers manipulating carbon content? Nitrogen? Other additions not prohibited by the 316L spec?
Thanks for any input you might have!
