It depends, as Valerie says each brewing method requires a different grind size. "For French press , pour over , and cold brew , it's better to use coarse grind than fine grind," she suggests, explaining, "This is because these brewing methods require water to be in contact with the grind longer fine grain vs coarse grain steels

Austenitic Grain-Size of Steel | Metallurgy

An inherently fine grained steel, if not heated above its grain coarsening temperature, retains the same actual austenite grain size, whereas an inherently coarse grained steel keeps continuously getting coarsened. The properties of a steel are affected only by the Austenite Grain Size - an overview | ScienceDirect TopicsAlso mentioned is the importance of austenite grain size in affecting N which arises from the grain boundary area available to provide nucleation sites for the pearlite. A fine-grained steel has more grain boundary area than a coarse-grained steel and consequently has 5 Engineering Aspects of Austenitic Grain Size | Speaking fine grain vs coarse grain steelsJun 15, 2010 · 4) In ASTM E 112, grain sizes can range from grain size number 1 (coarse grain) to grain size number 8 (fine grain). 5) Impact strength at a given hardness, yield strength, % elongation, distortion in heat treatment , machinability,and ability to be plastically deformed are all material characteristics that are influenced by grain size.
