What is the difference between 304, 304H and 304L?Type 304 refers to those materials widely used in the manufacture of wire mesh, which contain 18% chromium or 8% nickel (18-8) on a stainless alloy basis, which will not rust when left outdoors and will not oxidize even when the temperature rises to
8k is actually a standard surface treatment of stainless steel. Stainless steel plate surface polishing and grinding, the surface is bright as a mirror, can shine things reflect people, called mirror 8k.We all know that stainless steel plate a chrome-nickel alloy steel, and 8k in the "8" refers to t
The common specifications of stainless steel wire mesh are 1mm-5mm, and the size of the mesh varies from 5cm-25cm. Stainless steel wire mesh specifications mainly from these three directions to see, respectively, mesh size, aperture, wire diameter, etc.. Common specification is the wire diameter, an
