For lighter specified wall thicknesses, the minimum elongation values shall be by agreement with the manufacturer. *** Applies to specified wall thicknesses (t) equal to or greater than 0.120'. For lighter specified wall thicknesses, the minimum elongation values shall be calculated by the formula: % elongation in 2' = 61t+12, rounded to the nearest percent. ** Applies to specified wall thicknesses (t) equal to or greater than 0.180'. For lighter specified wall thicknesses, the minimum elongation values shall be calculated by the formula: % elongation in 2' = 56t+17.5, rounded to the nearest percent. * Applies to specified wall thicknesses (t) equal to or greater than 0.120'.

Tubes are typically stocked in grade G2 gray iron or 65-45-12 Ductile, but most stocked sizes and any grade of O.D. Trepanned tubes are stocked in 72' lengths, but can be produced in longer lengths upon request. tube will receive a tube which is 3.110' O.D. Wall thickness minimums are based on actual O.D. Stock Allowances - Cast Iron Tubes (Gray, Ductile, or Ni-Resist) *** - Turned OD Tolerance is +.080'/-0' and Finish Size is 0.250' below turned OD A 3.000” bar is guaranteed to finish at 3.000”. Stock allowance is a function of the bar diameter. Round bars are made with sufficient stock on the outside diameter to guarantee clean-up at the nominal dimensions.
