RE: [MW:9842] RE: 9821] SA 516 Gr.60 high in manganese-accept or reject

Dear Sir,

 

I think you are right, for thickness under 12,5 mm the max. Mn content should be 1.30% for product analyze. I didn’t  looked at note C but this one is applicable here.

 

Met vriendelijke groeten / Best Regards

Mr.Herman Piper,

                          You can't accept the material since the note C is very clear for thickness of plates under 12.5 mm the note B is not applicable

put your comments if I am wrong

Dear Krishna,

 

Acceptation depends on the carbon content of your material. Table 1 of SA516 shows a limit of 0.55 – 0.98 (product) for Mn, but when you look at the front of the table there is a remark B. Look at this remark and you will see that the max. allowed Mn content may be higher as the given limits, even up to 1.60 % (product analyses), when there is less carbon present than the max. 0.21%. For each 0.01 % less carbon you may add 0.06 Mn to the upper limit, this means that the max. allowed carbon content will be 0,13%. If that is the fact than you can accept the material, if not you should reject it.
