The designation "1.0736" is unfamiliar. Can you give a more common description?
I suppose we could look up these chemical ranges and find one or more steel grades to match, but this would be laborious and uncertain.
Even then, it seems that pinholes and blowholes would be unlikely in the parent material. Much more plausible would be problems in some welding process. Could this be where your problem lies?

the other names of grade are 9SMn36,S300 and sometimes 11SMn37.
more spesification:
Chemical composition % of the ladle analysis of grade 11SMn37 (1.0736)
Steel not intended for heat treatment
If, by metallurgical techniques, the formation of special oxides is guaranteed, a
Si content of 0.10 to 0.40 % can be agreed
Elements not listed in this table shall not be intentionally added to the steel without the agreement of the purchaser, other than for the purpose of the finishing the heat. However, elements such as Te, Bi etc., may be added by the manufacturer for improving the the machinability, if this has agreed at the time of enquiry and order.

you know that there are some standards for the level of acceptance of pinholes and blowholes for killed steels, but i want to know that what is the level of this steel(semikilled, rimmed or capped) and what is the acceptance limit for that?
