[MW:10158] Re: THROUGH THICKNESS DUCTILE TESTING

Dear Manoj,

This requirement should be taken in account when purchasing steel
plates. Executing a normalizing heat treatment afterwards on rejected
plates will normalize your material structure but mostly not dissolve
the present manganese sulphite inclusions which often causes not
satisfying the required % RA. So in such case in my opinion you need
to order new material with the required Z quality mentioned in your
purchase order.

Best Regards,

Herman Pieper
