 a. The sum of chromium and molybdenum shall not exceed 0.32 % on heat analysis; by agreement, the heat analysis limit for V and Cb, or
 both, may be increased up to 0.10 % and 0.05 %, respectively; see ASTM A 350 for details.
 b. The sum of copper, nickel, chromium and molybdenum shall not exceed 1.00 % on heat analysis.
 c. Product analysis.
 Single values are maximum, unless otherwise specified.
 Although sulphur and phosphorus contents are not listed in this table due to space limitation, they are specified, see the appropriate ASTM
 standard for details.
