304L stainless steel, also known as ultra-low carbon stainless steel, is a versatile stainless steel material, which is widely used to produce equipment and components requiring good comprehensive properties (corrosion resistance and formability).

304L stainless steel is a versatile stainless steel material.

304L Stainless Steel Brand:

Old standard JB/T 4237-1992 corresponds to 00Cr19Ni10

New Standard GB/T 20878-2007 Stainless Steel and Heat Resistant Steel Brand and Chemical Composition

Stainless steel plate and strip for pressure equipment GB 24511 2009

For the corresponding 022Cr19Ni10, its carbon content is about 0.03%.

Unified digital code S30403 differs from 30408
