Re: [MW:12597] HARDNESS MEASUREMENT MAP

Dear Sir,

Our client insisted to have values of shell harndess to make sure that they are within NACE MR 0175 (22 HRC max hardness).

2011/10/1 sudhir singh <sa1mad38@yahoo.com>

As such hardness test for 316L is not required after or prior to hydrotest.

Dear Experts,

We have completed sucessfully Hydrotest of our two SS 316L vessles. 

For stress relieiving reasons, we have asked our supplier and since the beginning, to foresee some spot checks on hardness of the shells.

Now, is there any standard mapping/ number of points to be checked??

Logically, the more strained fiber is by the external surface of the shell, so which points to select or hardness testing??

Many thanks for a prompt reply

Regards,
