Stainless steel wire mesh smooth shiny surface, but sometimes there will be some dark, black color.Is the material we have a problem? But with stainless steel potions test fluid measurement is 304 material, yes, what reason is this?

Stainless steel wire mesh is mainly iron, nickel, chromium inside three metal alloys.Three elements can be different.Iron content of chromium content for a bright, same as dark nickel content. But the high iron content is more dark.So can't by the brightness ratio to determine its content. Stainless steel wire mesh surfaces because the results of the stainless steel wire is heated oxidation.Stainless steel wire in the process of drawing, wire drawing machine lubrication is not good, the friction resistance is big, fever caused by serious segregation, stainless steel wire rod surface precipitation is internal alloy composition, is very hard not too good.

By oil effectively to avoid black stainless steel wire is to reduce the friction resistance of stretch, not on high temperature wire surface form, realize the heat dispersion in a timely manner.The speed of wire drawing machine will also be cut appropriately to avoid thermal oxidation of stainless steel wire.
