ALLOY MATERIAL ADJUSTMENT NOTES
1. Apply the appropriate multiplier above to the corresponding Carbon Steel labor operation.
2. Adjustments shown above apply to all wall thicknesses.
3. The molybdenum content in alloys listed in Groups 1 through 3 inclusive, shall not exceed 1%.
4. Adjustments for alloys other than those listed above will have to be researched. Consult Piping lead engineer.
5. Low Temp Carbon Steel type ASTM-A333 Gr. 6 is standard Carbon Steel material and alloy adjustments do not apply.
6. Where standard Carbon Steel welding procedures and filler metal can be used, alloy adjustments will not apply to Low Temp Carbon Steel types ASTM A333 Gr. 1 and ASTM A333 Gr. 9. Consult Piping lead engineer.
