ASME FFS-1/API-579-1-----Hardness and Tensile
ASME FFS-1/API-579-1-----Hardness and Tensile
(OP)
Good evening.
I have question on Table 2E.1 (by using this table tensile strength can be estimated by using hardness value).
If hardness value is 90 BHN. Lowest value as per Table 2E.1 is 114 HBN. How to estimate tensile strength for 90 BHN? table does not enlist lower than 114 BHN. Any idea?

Plant got fire due to leakage of propane. Hardness survey was performed on affected piping, material of construction is A671 CC65. Minimum hardness value we did measure 90 and max 129. Average is 114. Almost 500 readings were taken on 12meter pipe.
