ASTM Steel Properties

ASTM Steel Properties

ASTM Steel Properties

(OP)
I often have a difficult time knowing what steel to spec for the minor uses...i.e a stainless steel rod, should it be A304, A307?

Does anyone know of a website or document that helps aid in this selection process?

RE: ASTM Steel Properties

Which stainless steel grade to use depends on the application.  A web search will generate a good sample of the products available.  304, 316, 410 and 430 are stainless steel grades I have seen used in transportation applications when specifying threaded fasteners.  304 is a general use grade with a fair amount of nickle and chromium.  316 is a better grade we use near marine environments and has molybdium <sp?> in addition to the other metals.  If you have strength requirements, as most applications will, you need to specify these as well because the chemical composition will not guarentee a specific strength.  Somtimes cold working or other treatment will be used to produce a part with a specific strength.
