Incoloy 800h Strip

Nickel-iron-chromium alloys that have the same basic composition as INCOLOY alloy 800 but with significantly higher creep-rupture strength. The higher strength results from close control of the carbon, aluminum and titanium contents in conjunction with a hightemperature anneal. Used in chemical and petrochemical processing, power plants for super-heater and reheater tubing, industrial furnaces and heat-treating equipment.STANDARD PRODUCT FORMSPipe, tube, sheet, strip, plate, round bar, flat bar, forgingstock, hexagon and wire.MAJOR SPECIFICATIONSUNS N08810, N08811BS 3072, 3073, 3074, 3075,3076 (NA15)ASTM A 240, A 480, B 163,B 366, B 407 – 409,B 514, B 515, B 564,B 751, B 775, B 829ASME SA-240, SA-480,SB-163, SB-366,SB-407 – SB-409, SB-514,SB-515, SB-564, SB-751,SB-775, SB-829ASME Code Cases 1325,1949, 1983, 2339,N-201, N-254DIN 17459, 17460Werkstoff Nr. 1.4876, 1.4958,1.4959VdTÜV 412, 434EN 10028-7, 10095ISO 4955A, 6207, 6208,9723, 9725LIMITING CHEMICAL COMPOSITION, %800HNi........30.0–35.0Fe.........39.5 min.Cr.......19.0–23.0C.........0.05–0.10Al........0.15–0.60Ti............0.15–0.60Al+Ti......0.30–1.20800HTNi........30.0–35.0Fe.........39.5 min.Cr.......19.0–23.0C.........0.06–0.10Al........0.25–0.60Ti............0.25–0.60Al+Ti......0.85–1.20* By special agreement, this product can besupplied withaluminum + titanium limited to 0.4 – 0.7%.PHYSICAL CONSTANTS AND THERMAL PROPERTIESDensity, Ib/in3(g/cm3)............................................0.287 (7.94)Melting Range, °F (°C)..............2475 – 2525(1357 – 1385)Specific Heat, Btu/lb•°F(J/kg•°C)......................... 0.11 (460)Curie Temperature, °F(°C)....................................-175 (-115)Permeability at 200 Oersted (15.9kA/m).....................1.014Coefficient of Expansion, 10-6 in/in•°F(μm/m•°C)70-200°F (20-100°C)...................... 7.9(14.4)Thermal ConductivityA, Btu•in/ft2•h•°F(W/m•°C)........80 (11.5)Electrical ResistivityA, ohm•circ mil/ft(μΩ•m)....... 595 (0.989)TYPICAL MECHANICAL PROPERTIES
