Although table 2 of ASTM B75, superscript F, allows for a light straightening operation, it is our opinion that superscript F is not specific in the desired procedure of straightening. Thus, for O50 and O60 tempers, a finish annealed tube may not meet the yield strength requirements listed in table 2. If meeting the 9 ksi min yield strength is required for your application, please advise the CSR at time of quote.
Why does Wieland Small Tube Products take exception to ASTM B75 yield requirements for light annealed (050) and soft annealed (060) tempers?
