fine grained steel or coarse grained steel Introduction

What are the properties of fine-grain steel? - Quora

Second, imagine in fine grained steels Grain A has 10 neighbour grains, in coarse grained steels Grain A has 5 neighbour grains. So if you want to strain grain A in fine grained steel you have 10 other neighbours that prevents you from straining grain A, in coarse grained steels that number is 5.
