Stainless Steel Material Wire Mesh Introduction
We all know stainless steel wire mesh, but do you know what is the difference the materials? How do you distinguish them? In this article, I will briefly introduce how to distinguish stainless steel material wire mesh of 201 and 304.
There are many kinds of stainless steel materials, such as 304, 304L, 316, 316L, 201, 202, etc. Stainless steel features: bright surface, soft, non-magnetic, anti-fatigue, large extension force, etc. The product specification range is large and the weight is small; The wire has high dimensional accuracy of up to ±0.005mm; the surface quality of the wire is good; after the heat treatment of the steel wire, the drawing of the small reduction surface is performed. The surface is bright, soft, anti-fatigue, and has certain extension force. Stainless steel spring wire: bright, strong elasticity, good wear resistance and compression resistance, good metallographic structure of the wire rod, uniform performance; stable chemical composition, small deviation The steel is pure and the content of inclusions is low; the hard line ratio of the product is high, the ratio of high quality is high, and the ratio of fine line is high. This article focuses on the differences between the 201 and 304 materials.
The chemical formula of 201 is 1Cr17Mn6Ni5, and the chemical formula of 304 is 06Cr19Ni10; the main difference between them is nickel-chromium element, 201 is 17 chromium, 5 chromium-nickel element also contains 6 manganese elements, and 304 is 19 chromium elements and 10 nickel elements; So they cause many differences in color, corrosion resistance, acid and alkali resistance, toughness and so on.
In terms of color, since 201 stainless steel contains manganese, the color will be darker than 304, and 304 will be whiter.
In terms of corrosion resistance, since 201 contains manganese, it will rust in a humid or salty environment for a long time, and 304 does not rust because it does not contain manganese.
From the acid and alkali resistance, 201 has a small content of nickel, and the acid and alkali resistance is not as good as 304.
From the toughness, the toughness of 304 is better, 201 is harder than 304, and the experiment is done with a hard knife. After the surface of 201 is scratched, there will be obvious scratches, and the surface of 304 will not have obvious scratches.
