What is the difference between SS316 and SS316L

The difference between SS316 and SS316L is that of suffix 'L'. This L stands for low carbon.

                            Chemical composition of SS316 and SS316L

                       Cmax    P       S         Si      Mn     Cr        Ni      Mo

     SS316       0.08   0.045   0.03   0.75   2.0   16-18   10-14   2-3
     SS316L     0.03   0.045   0.03   0.75   2.0   16-18   10-14   2-3

From the above table we can see that SS316L has a 0.03% max carbon where as SS316 has a 0.08% max carbon. The low carbon in SS316L improves its wediability at high temperature. In a corrosive environment,SS316L used to minimize intergranulor corrosion.

  4. Apart from this, 316L is also preferred over other steels in nuclear industry for applications in radiation (particularly neutron radiation) environment, as carbon in steels gets radioactive; C-12 takes up neutrons to become C-14. The low carbon content of 316L helps minimize this effect.
