No limits, values reported
Silicon, when required, is commonly specified as 0.10% max or a range such as 0.15 to 0.35%. Lead (0.15 to 0.35%, letter L) and boron (0.0005 to 0.003%, letter B) versions of the standard grades are identified by a letter between the second and third digits. Residual elements are agreed between purchaser and supplier; unless otherwise specified Option B applies. Option A applies to flat rolled products up to 1060.
