Grain size of stainless steel
WebJul 31, 2024 · The average grain size of an alloy is generally expressed in terms of the grain size number, G, as indicated in the standard ASTM E112 - 13 [4]. The value of G ranges from 00 to 14 where 00 corresponds to an average grain diameter of 0.508 mm and area of 0.2581 mm 2 and 14 a diameter of 2.8 µm and area of 7.9 µm2. WebSAE 304 stainless steel is the most common stainless steel.The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%) metals as the main non-iron constituents.
