Allowable stressesare reprinted here by permission of theASME.NOTE (1)Due to the relatively low yield strength of this material, thesehigher stress values were established at temperatures wherethe short time tensile properties govern to permit the use ofthese alloys where slightly greater deformation is acceptable.These higher stress values exceed 67%, but do not exceed90% of the yield strength at temperature. Use of these stressmay result in dimensional changes due to permanent strain.These stress values are not recommended for flanges ofgasketed joints or other applications where slight amounts ofdistortion can cause leakage or malfunction.HAYNES ® 556 TM alloyASME Vessel Code Allowable StressesMetalMaximum Allowable Stress ValuesTemperaturesNot ExceedingStandardNote (1)°F °C Ksi (MPa) Ksi (MPa)100 37 25.0 (172) 25.0 (172)200 93 25.0 (172) 25.0 (172)300 149 23.1 (159) 24.5 (168)400 204 21.3 (146) 23.7 (163)500 260 20.1 (138) 23.1 (159)600 315 19.3 (133) 22.8 (157)650 343 19.0 (131) 22.7 (156)700 371 18.7 (129) 22.5 (155)750 398 18.5 (127) 22.4 (154)800 426 18.2 (125) 22.3 (153)850 454 18.0 (124) 22.2 (153)900 482 17.8 (122) 22.1 (152)950 510 17.6 (121) 21.8 (150)1000 537 17.4 (120) 21.6 (148)1050 565 17.2 (118) 21.4 (147)1100 593 17.1 (118) 20.8 (143)1150 621 16.9 (116) 16.9 (116)1200 648 13.6 (93) 13.6 (93)1250 676 10.9 (75) 10.9 (75)1300 7048.8 (60) 8.8 (60)1350 7327.0 (48) 7.0 (48)1400 7605.6 (38) 5.6 (38)1450 7874.5 (31) 4.5 (31)1500 8153.6 (25) 3.6 (25)1550 8432.8 (19) 2.8 (19)1600 8712.2 (15) 2.2 (15)1650 8981.8 (12) 1.8 (12)18
