Stabilization Heat Treatment: Heat to 1550°F±15°(845℃±89,hold at heat for 4 hr±0.5,and cool in air.
Precipitation Heat Treatment:Heat to 1400°F±15°(760°C±8²),hold at heat for 16 hr±1,and cool in air.
Properties:The product shall conform to the following requirements:
Tensile Properties of Waspalloy forged bars:Shall be as follows on product 3.25 in.(82.5 mm)and under in nominal cross-section dimension,determined in accordance with ASTM E8.Tensile property requirements for product over 3.25 (82.5 mm)in nominal cross-section dimension shall be as agreed upon by purchaser and vendor.
Tensile Strength,min 160,000 psi (1103 MPa)
Yield Strength at 0.2%Offset,min 110,000 psi(758 MPa)
Elongation in 2 in.(50 mm)or 4D,min 15%
Reduction of Area,min 18%
Tensile property requirements of apply to both the longitudinal and transverse directions except that transverse tests are not required on product from which a test speci-men not less than 2.50 in.(63.5 mm)in length can be obtained.Specific orientation and location of specimens from Waspalloy forgings rings shall be as agreed upon by purchaser and vendor.Longitudinal tensile properties need not be determined on product tested in the transverse direction,unless otherwise specified by purchaser.
Hardness:Should be 321-403 HB or equivalent,determined in accordance with ASTM E10,but the product shall not be rejected on the basis of hardness if the tensile property requirements are met.
Stress-Rupture Properties of Waspalloy forged parts :Shall be as follows;testing of notched specimens and of combination smooth-and-notched specimens shall be performed in accordance with ASTM E292 and of smooth specimens in accordance with ASTM E139:
At 1350°F(732°C):A combination smooth-and-notched test specimen machined to the dimensions shown in Fig.1 and Table I,maintained at 1350°F±3(732°C±2°)while a load sufficient to produce an initial axial stress of 75,000 psi(517 MPa)is applied continuously,shall not rupture in less than 23 hours.The test shall be continued to rupture without change of load.After the 23 hr,if rupture occurs in the notch,the smooth section shall,by suitable means,be continued to rupture or a separate smooth specimen shall be tested to rupture in not less than 23 hours. Elongation of the smooth section after rupture,measured at room temperature,shall be not less than 8%in 4D.
As an alternate procedure,separate smooth and notched specimens,machined from adjacent sections of the same piece,with gage sections conforming to the respective dimensions of Table I may be tested individually under the above conditions.The smooth specimen shall not rupture in less 23 hr and elongation after rupture,measured at room temperature,shall be not less than 8%in 4D.The notched specimen shall not rupture in less than 23 hr but need not be tested to rupture.
The tests may be conducted using a load higher than required to produce an initial axial stress of 75,000 psi(517 MPa)but load shall not be changed while test is in progress.Time to rupture,rupture location,and elongation requirements shall be as specified
When permitted by purchaser,the tests may be conducted using incremental loading.In such case,the load required to produce an initial axial stress of 75,000 psi(517 MPa)shall be used to rupture or for 23 hr,whichever occurs first.After the 23 hr and at intervals of 8-16 hr,preferably 8-10 hr,thereafter,the stress shall be increased in increments of 5000 psi(34.5 MPa).Time to rupture,rupture location,and elongation requirements shall be as specified
At 1500°F(815°C):A tensile specimen,maintained at 1500°F±3°(815³C±2°)while a load sufficient to produce an initial axial stress of 40,000 psi (276 MPa)is applied continuously,shall not rupture in less than 23 hours.The test shall be continued to rupture without chauge of load.Elongation after rupture,measured at room temperature,shall be not less than 5%in 4D.
The test of may be conducted using a load higher than required to produce an initial axial stress of 40,000 psi (276 MPa)but load shall not be changed while test is in progress,Time to rupture and elongation requirements shall be as specified
When permitted by purchaser,the test muy be conducted using incremental loading.In such case,the load required to produce an axial stress of 40,000 psi (276 MPa) shall be used to rupture or for 23 hr,whichever occurs first.After the 23 hr and at intervals of 8-16 hr,preferably 8-10 hr,thereafter,the stress shall be increased in increments of 5000 psi(34.5 MPa).Time to rupture and elongation requirements shall be as specified
Grain Size of Waspalloy forged rings :Shall be predominately 3 or finer with occasional grains as large as 1 permissible, determined by comparison of a polished and etched specimen with the chart in ASTM E¹12.
