1/ This table lists the maximum range for elements of the manufacturer's established
chemical composition.
2/ Phosphorus and sulfur shall be controlled to the lowest attainable levels but in no case
shall the combined phosphorus and sulfur content exceed 0.025 percent.
3/ When the amount of boron is specified in the alloy, its content so determined by heat
analysis shall not exceed 0.003%.
4/ When the amount of an element is less than 0.02% the analysis shall be reported as 0.02%.
5/ Elements not listed in table, but intentionally added, shall be reported.
