Product Parameters



304L Stainless steel sheet manufacturer

304L stainless steel, also known as ultra-low carbon stainless steel, is a kind of universal stainless steel material, widely used in the production of equipment and parts requiring good comprehensive properties (corrosion resistance and formability).

304L Stainless steel sheet Price in China ,Manufacturer of 304L Stainless Steel sheet

304L stainless steel is a kind of universal stainless steel material.
304L stainless steel grade:
The old standard JB/T 4237-1992 corresponds to 00Cr19Ni10
New standard GB/T 20878-2007 Stainless steel and heat resistant steel grades and chemical composition
And GB 24511 2009 stainless steel plates and strips for pressure bearing equipment
The above corresponds to 022Cr19Ni10, which contains about 0.03% carbon
Uniform digital code S30403 is different from S30408 of 304

This is the most cost effective grade of steel. So the 304L Stainless Steel Sheet Price is lower compared to other grades of stainless steels and all metallic products in general. There are different versions of the material with low carbon and high carbon content.  The low carbon version, 304L sheets are very good for welding applications as they have less carbide precipitation and less localized corrosion.
