         该合金的镍含量达32%，因而能耐氯化物的应力腐蚀开裂，并对σ相的析出不敏感。在固溶处理状态下，800H和800AT合金具有优良的抗蠕变和应力开裂的能力。800H和800AT合金通常用于在约593℃的温度环境中需更高的抗蠕变和应力开裂能力的地方。上述三种不同的800合金已作为结构材料被列入ASME锅炉和压力容器第一卷电站锅炉，第三卷核电锅炉和第八卷非火压力容器规范中。
          800和800H，800AT合金除碳含量不同，及在800AT合金中还含有达1%的铝和钛外，其余化学成份均相同。800合金Incoloy系列合金管件分三种，Incoloy800，Incoloy800H，Incoloy800AT，该合金是抗高温氧化及抗高温渗碳的镍-铁-铬合金。该合金的镍含量达32%，因而能耐氯化物的应力腐蚀开裂，并对σ相的析出不敏感。该合金具有优良的耐均匀腐蚀性能。在固溶处理状态下，800H和800AT合金具有优良的抗蠕一般用于约593℃的温度环境中。
Alloy pipes with excellent resistance to uniform corrosion properties. In the solution, 800H and 800AT alloy has excellent resistance to creep properties of uniform corrosion resistance of fine. Ability of chloride stress corrosion cracking, and the separation of σ phase. Alloy pipes in certain condition can show significant performance, according to certain standards and forms, good use of performance and operation technology value. This alloy is Incoloy series alloy pipes, Incoloy800, three Incoloy800H, Incoloy800AT, this alloy is resistant to high temperature oxidation and carburizing nickel - iron - chromium alloy.
The content of the nickel alloy, thus capable of 32% chloride stress corrosion cracking, and the separation of σ insensitive. In the solution, 800H and 800AT alloy has excellent resistance to creep and stress cracking ability. 800H and 800AT alloy commonly used in approximately 1365 degrees Celsius in the environment to higher resistance to creep and stress cracking ability. The above three different 800 alloy was listed as structural materials ASME boiler and pressure vessel first volume of nuclear power plant boiler, the boiler and pressure vessel roll the eighth in the fire.
8 and 800H, except the carbon content of different 800AT alloy, and in 800AT alloy with 1% of aluminum and titanium, the chemical ingredients are the same. Incoloy series 800 alloy alloy pipes, Incoloy800, three Incoloy800H, Incoloy800AT, this alloy is resistant to high temperature oxidation and carburizing nickel - iron - chromium alloy. The content of the nickel alloy, thus capable of 32% chloride stress corrosion cracking, and the separation of σ insensitive. This alloy is uniform corrosion resistance performance of the fine. In the solution, 800H and 800AT alloy has excellent resistance to creep about 1365 degrees commonly used for the temperature environment.
