304L stainless steel plate

 

Type 304L is the low carbon version of 304. It is used in heavy gauge components for improved weldability. Some products such as plate and pipe may be available as "dual certified" material that meets the criteria for both 304 and 304L.

 

1,Q: What is 304L stainless steel plate?

A: Low-carbon austenitic stainless steel (18% Cr, 8-12% Ni, ≤0.03% C), corrosion-resistant, weld-friendly, and ideal for post-weld applications.

 

2,Q: What are its key mechanical properties?

A: Tensile strength: 485-655 MPa; Yield strength: ≥170 MPa; Elongation: ≥40%; Hardness (HB): ≤201.

 

3,Q: What applications is it suited for?

A: Chemical processing equipment, pressure vessels, marine components, food machinery, and welded structures requiring corrosion resistance.

 

4,Q: Which international standards apply to it?

A: ASTM A240 304L, JIS G4305 SUS304L, GB/T 3280 06Cr19Ni10, EN 10088-2 X5CrNi18-10.

 

5,Q: How does it differ from 304 stainless steel?

A: 304L has lower carbon (≤0.03% vs. ≤0.08% for 304), better resistance to intergranular corrosion after welding, and slightly lower strength.
