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.

 

Met vriendelijke groeten / Best Regards
