316 and 316L difference
Nov 23, 2017

The difference between 316 and 316L is following.

1. Grade difference

   316 0Cr17Ni12Mo2(old) 06C17N12M2(New)

   Equal to ASTM TP316, JIS SUS316

   316L 00Cr17Ni14Mo2(old) 022C17N12M2(New)

   Equal to ASTM TP316L, JIS SUS316L

2. Components

  316   

C0.08,Si1.0, Mn2.0, P0.035, S0.03,Ni:10.0-14.0,Cr:16.0-18.5, Mo:2.0-3.0

316L

C0.03,Si1.0, Mn2.0, P0.035, S0.03,Ni:10.0-14.0,Cr:16.0-18.5, Mo:2.0-3.0

3. Yield strength

  316  210(N/MM2)

  316L  180(N/MM2)

4. Tensile strength

  316  520(N/MM2)

  316L  480(N/MM2)

 

The above is the mainly difference between 316 and 316L.

And 316L with low carbon, so the carbon is very difficult to be separated to form chromium carbide. This property make it is difficult to get rusted.
