Difference between 316 stainless and 316L stainless steel

We can offer ASTM 316,316L stainless steel stock.Here is Difference between 316 stainless and 316L stainless steel

ASTM 316 Grade 0Cr17Ni12Mo2 (old number) 06C17N12M2 (new grade) equivalent to American Standard TP316, JIS SUS316, is simply 316 ASTM 316L grades 00Cr17Ni14Mo2 (old number) 022C17N12M2 (new grade) equivalent to American Standard TP316L, Japanese standard SUS316L, is simply 316L material.

ASTM 316 Chemical composition:

C ≤ 0.08 ， Si ≤ 1.00 ， Mn ≤ 2.00 ， P ≤ 0.035 ， S ≤ 0.03 ， Ni:10.0-14.0 ， Cr:16.0-18.5 ， Mo:2.0-3.0 。

ASTM 316L Chemical composition:

C ≤ 0.03 ， Si ≤ 1.00 ， Mn ≤ 2.00 ， P ≤ 0.035 ， S ≤ 0.03 ， Ni:10.0-14.0 ， Cr:16.0-18.5 ， Mo:2.0-3.0

Different yield strength

316 210 (N/MM2)

316L 180 (N/MM2)

Tensile strength of different

316 520 (N/MM2)

316L 480 (N/MM2)

These are 316 stainless steel and 316L stainless steel are different. More simply, the biggest difference is the use of ultra-low carbon 316L stainless steel, so welding, 316L stainless steel and chrome carbon precipitates easily combined into chromium carbide can reduce the welded portion corrosion.
