What Are Cold Rolled finishes?StandardsPost Production Processing to Improve Corrosion ResistanceDifferences Between AlloysCold rolled finishes apply to flat products such as sheet or coil, with thickness less than about 5mm and usually less than 3mm. They are firstly hot rolled into a strip (or cast into a slab which is hot rolled into a strip) and then cold rolled. Cold rolling reduces the thickness by at least 50%. This smooths the surface, refines the grain structure and causes differences in the mechanical properties along and across the rolling direction. In the case of austenitic and duplex alloys, the proPeople also askWhat is 420 stainless steel?What is 420 stainless steel?420 stainless steel. Lower carbon content (<.5%) than the 440 series makes this steel extremely soft, and it doesn't hold an edge well. It is used often for diving knives, as it is extremely stain resistant. Also used often for very inexpensive knives.Differance between 420 and 440 stainless steel - BEBON
