Features
304L stainless steel strip is 300 series stainless steel, which is one of the most widely used stainless steel strips due to its corrosion resistance and nice fabrication.
Both 304 and 304L stainless steel strips can be used for many similar applications and the differences are minor, but they really do exist. 304L stainless steel strip has lower carbon contents than 304 stainless steel coil.
304L stainless steel is a kind of universal stainless steel material.

Advantages
304L is one of the most popular stainless steel materials, and it has good corrosion resistance because it has 18% chromium and 9% nickel content.
When selecting stainless steel materials for various industries, 304L stainless steel strips are often chosen because of their many advantages.
The following are the advantages of 304L stainless steel strips:
it has better processing properties than 201 and 304L, it can be more widely used in production;
hardening tendency during work;
treatment;
Different finish treatments can be given to the surface of 304L stainless steel strip to obtain excellent surface conditions such as bright surface or mirror surface;
resistance and high temperature oxidation resistance.
