316L stainless steel plate

Q: What is 316L stainless steel plate

?A: Low-carbon austenitic stainless steel (16-18% Cr, 10-14% Ni, 2-3% Mo, ≤0.03% C), featuring excellent corrosion resistance and weldability, especially post-welding.

 

Q: What are its key mechanical properties?

A: Tensile strength: 485-655 MPa; Yield strength: ≥170 MPa; Elongation: ≥40%; Hardness (HB): ≤217.

 

Q: What applications is it suitable for?

A: Chemical processing equipment, marine engineering, coastal architecture, food/beverage machinery, medical devices, and welded structures in harsh corrosive environments.

 

Q: Which international standards apply to it?

A: ASTM A240 316L, JIS G4305 SUS316L, GB/T 3280 022Cr17Ni12Mo2, EN 10088-2 X2CrNiMo17-12-2.

 

Q: How does it differ from 316 stainless steel?

A: 316L has lower carbon (≤0.03% vs. ≤0.08% for 316), better resistance to intergranular corrosion after welding, and slightly lower tensile/yield strength.
