〣Introduction
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 good comprehensive performance (corrosion resistance and formability) of equipment and parts.
304L Stainless Steel Brand:
The old standard JB/T 4237-1992 corresponds to 00Cr19Ni10
New standard GB/T 20878-2007 stainless steel and heat-resistant steel grade and chemical composition
And GB 24511 2009 stainless steel plates and strips for pressure equipment
The above corresponds to 022Cr19Ni10, and its carbon content is about 0.03%
The unified digital code S30403 is different from the S30408 of 304
〣Chemical composition

12.1 16.3 21.4
Linear expansion coefficient α/(10-6/℃) (between the following temperatures /℃)
20 ~ 100 20 ~ 200 20 ~ 300 20 ~ 400
16.0 16.8 17.5 18.1
Resistivity 0.73 Ω·mm2·m-1

304L is a variant of the lower carbon 304 stainless steel for use in welding situations. The lower carbon content minimizes the carbide precipitation in the heat-affected zone near the weld, which may lead to intergranular corrosion (welding erosion) of stainless steel in some environments.
