① Manganese may exceed 1.35 % on heat analysis, up to a maximum of 1.60 %, provided that the carbon equivalent on heat analysis does not exceed 0.47 %, or the value specified in Supplementary Requirement S77 when that requirement is invoked, when based on the following formula：
CE = C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15%
When this option is exercised, the manganese content on product analysis shall not exceed the heat analysis content by more than 0.12 percentage points.
② By agreement, the steel may be produced with titanium, in which case the minimum aluminum content shall not apply. When this option is exercised, the titanium content, by heat analysis, shall be .006 % to 0.02 %, and the actual titanium content shall be reported on the test report.
