- A) Where an ellipsis(***) appears in this table , there is no requirement ,but the analysis shall be reported
- B)The sum of copper , nickle , chromium and molybdenum shall not exeed 0.50% on heat analysis . When one or more of these elements are specified , the sum does not apply ; in which case , only the individual limits on the remaining unspecified elements will apply . The limits for steel whose carbon content is 0.02% or less are :
Heat analysis 0.045%
Product analysis 0.055%
-
C) If the hardness result is 85 HRB or higher , no tension test is required
