304L Stainless Steel Sheet/Plate:
304L stainless steel, also known as ultra-low carbon stainless steel, is a versatile stainless steel material that is widely used to make equipment and components that require good overall performance (corrosion resistance and formability).
- 304L stainless steel is a versatile stainless steel material.
- 304L stainless steel number:
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 Equipment
On the corresponding 022Cr19Ni10, its carbon content of about 0.03%
Unified digital code S30403 is different from 304 S30408
304L is a variant of 304 stainless steel with a low carbon content and is used where welding is required. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone near the weld, and the precipitation of carbides may result in intergranular corrosion of the stainless steel in some environments (weld erosion).
