Grain structure of stainless steel
WebMar 6, 2024 · The grain direction is in the rolling direction of the sheet as it was being manufactured. Two rollers compressing the hot metal cause the polycrystalline material to elongate in the direction of rolling. Once the crystallites are elongated, they appear as the grain that we see in cold-rolled steel. WebStainless steels are alloys, as are brasses (copper + zinc), bronzes (copper + tin), the many alu- minum alloys, and many other me- tallic materials. In general, solid metals and …
