NBT_47010-2010_ Standard stainless steel forgings have alternative designations; I would like to know how grades I and II should be indicated. For example, for OCr18Ni9 forgings, it is S30408Ⅰ； S30408Ⅱ ； In the NBT_47008-2010 standard, there is no alternative in the form of forgings for carbon steel; so how should forgings be denoted? For example, for 16Mn, it should be written as 16MnⅠ ； 16MnⅡ ； 20 steel forging 20Ⅰ ； 20Ⅱ ； Please support!
