INCOLOY® alloy 909 (UNS N19909) is a nickel-ironcobalt alloy whose outstanding characteristics are a c***tant low coefficient of thermal expansion, a c***tant modulus of elasticity, and high strength. The alloy is strengthened by a precipitation-hardening heat treatment made possible by additi*** of niobium and titanium. The chemical composition of INCOLOY alloy 909 is given in Table 1. The combination of low expansion and high strength makes INCOLOY alloy 909 especially useful for gas turbines. The low expansion enables closer control of clearances and tolerances for greater power output and fuel efficiency. The high strength increases strength-to-weight ratios for lower weight in aircraftengines. For those reas***, INCOLOY alloy 909 is used for gas-turbine vanes, casings, shafts, and shrouds. The properties of INCOLOY alloy 909 areattractive also for rocket-engine thrust chambers, ordnance ha***are, springs, steam-turbine bolts, gauge blocks, instrumentation, and glass-sealing applicati***.

In the continuing evolution of ***C-developed low coefficient of expansion superalloys, Special Metals Corporation has introduced INCONEL® alloy 783, offering these improvements over INCOLOY alloy 909: - Excellent resistance to oxidation to 1300°F (704°C) - Resistance to SAGBO comparable to that of INCONEL alloy 718 - 5% lower density than alloys 909 and 718 -Better impact resistance -Processing characteristics comparable to alloy 718 *Reference to the ‘balance’ of a composition does not guarantee this is exclusively of the element mentioned but that it predominates and others are present only in minimal quantities.

特性:
Incoloy 800H和800HT为一双重验证之铁镍铬合金,具800合金之基本化学成分,惟因控制其碳、铝及钛含量及高温退火处理,800H/800HT合金巨幅提高其蠕变断裂强度。低碳含量亦加强其耐应力断裂特性,添加铝及铁则提高其耐高温强度。Incoloy 800H 和800 HT 都是镍铁铬合金,因含有 铝, 碳和钛成份, 该合金有很高的抗拉强度, 高强度的结果接近控制碳、铝、钛含量与高温退火.
应用领域:
用于化工、石油化工加工、发电厂,电站超热油管、加热器、工业炉窑和热处理设备等领域.
