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

Alloy 304 is a T-300 series stainless steel austenitic, which has a minimum of 18% chromium and 8% nickel with a maximum of 0.08% carbon. It is the standard "18/8 stainless steel" commonly used in pans and cooking tools. Alloy 304 is the most versatile and widely used alloy in the stainless steel family. It is used in a wide range of domestic and commercial applications, has excellent corrosion resistance, high ease of fabrication, outstanding formability and great strength. Austenitic stainless steel is also considered to be the most weldable high-alloy steel and can be welded by all fusion and resistance welding processes. With its controlled carbon content of 0.04 to 0.10, Alloy 304H provides improved high temperature strength at temperatures above 800oC Fahrenheit. Alloy 304H offers greater short and long term creep strength at temperatures above 500oC and is more resistant to sensitization than Alloy 304L.
