| # Incoloy alloy a286 properties Incoloy Alloy A286 (also known as A286 stainless steel) is a nickel and iron-based, austenitic superalloy that is useful for applications requiring high strength and corrosion resistance up to 1300°F (704°C), and for lower stress applications at higher temperatures. The mechanical properties of this alloy are developed by suitable solution annealing and precipitation hardening treatments. This alloy has excellent high temperature oxidation resistance and is designed to maximize creep and stress rupture properties, with some reduction in strength. A-286 material can attain high strength levels when aged after cold work, and has wide applications in high temperature fasteners and springs. We stock A286 steel in round bar (AMS 5731, 5732, 5737), sheet and coil forms (AMS 5525, 5858), with a variety of cutting and processing services available. # Incoloy alloy a286 Standard Stock Specifications A-286 Sheet, Coil and Bar: ► UNS S66286 ► ASTM A 453 ► ASME SA 453 A-286 Sheet: ► AMS 5525 ► AMS 5858 A-286 Bar: ► AMS 5731 ► AMS 5732 ► AMS 5737 ► ASTM A 638 # Incoloy alloy a286 Other industry standards we comply ► EN 1.4980 ► DIN EN 10204 3.1 ► PWA-LCS ► S1000 / S-SPEC-1 ► GE Aviation S-SPEC-35 AeDMS S-400 ► RR SABRe Edition 2 ► DFARS Compliant # Incoloy alloy a286 Common Trade Names ► Incoloy Alloy A286 ► Pyromet Alloy A-286 ► ATI A286 ► A286 Steel # Incoloy alloy a286 Common Applications - Jet engine components

# Resistance to Corrosion and Oxidation Type A286 alloy content is similar in chromium, nickel, and molybdenum to some of the austenitic stainless stees. Consequently, this alloy possesses a similar level of aqueous corrosion resistance to these grades. In higher temperature services, the level of corrosion resistance to atmospheres such as those found in jet engine applications is excellent to at least 1300°F (704°C). Oxidation resistance is high for continuous service up to 1500°F (816°C) and intermittent service up to 1800°F (982°C). # Incoloy alloy a286 Chemical Composition | | Element | Percent by Weight | | C | Carbon | 0.08 maximum | | Mn | Manganese | 2.00 maximum | | P | Phosphorus | 0.025 maximum | | S | Sulfur | 0.025 maximum | | Si | Silicon | 1.00 maximum | | Cr | Chromium | 13.50 - 16.00 | | Ni | Nickel | 24.00 - 27.00 | | Mo | Molybdenum | 1.00 - 1.50 | | Ti | Titanium | 1.90 - 2.35 | | V | Vanadium | 0.10 - 0.50 | | Al | Aluminum | 0.35 maximum | | B | Boron | 0.003 - 0.010 | | Fe | Iron | Balance | # Incoloy alloy a286 Alloy A286 Physical Properties Physical properties | | Solution Treated | Solution Treated and Aged | | Density | 0.286 lb./in3 (7.92 g/cm3) | 0.287 lb./in3 (7.94 g/cm3) | | Specific Gravity | 7.92 | 7.94 | | Melting Range | 2500 - 2600 °F | 1370 - 1430 °C | | Magnetic Permeability | 1.010 | 1.007 | Thermal Conductivity | Temperature Range | Linear Coefficients of Thermal Expansion · 10-6 | | °C | °F | /°C | /°F | | 21 - 93 | 70 - 200 | 16.5 | 9.17 | | 21 - 204 | 70 - 400 | 16.8 | 9.35 | | 21 - 316 | 70 - 600 | 17.0 | 9.47 | | 21 - 427 | 70 - 800 | 17.4 | 9.64 | | 21 - 538 | 70 - 1000 | 17.6 | 9.78 | | 21 - 649 | 70 - 1200 | 17.8 | 9.88 | | 21 - 760 | 70 - 1400 | 18.6 | 10.32 | Thermal Conductivity | Temperature Range | Coefficients | | °C | °F | W/m·K | Btu/(hr/ft²/in/°F) | | 150 | 302 | 15.1 | 8.7 | | 300 | 572 | 17.8 | 10.3 | | 500 | 932 | 21.8 | 12.6 | | 600 | 1112 | 23.9 | 13.8 | Specific Heat 420 Joules/kg °K (Btu/lb/°F) Electrical Resistivity | Temperature | microhm-cm | | °C | °F | | 25 | 77 | 91.0 | | 540 | 1004 | 115.6 | | 650 | 1202 | 118.8 | | 730 | 1346 | 120.1 | | 815 | 1499 | 122.4 | # Incoloy alloy a286 Mechanical Properties and Yield Strength A286 alloy is formed most easily in the solution treated condition.
