  材料特性 Material Characteristics

  1.在高达500℃的极高温的水性介质中具有出色的抗腐蚀性。

  2.很好的抗应力腐蚀的性能。

  3.很好的加工性。

  金相结构: 800H为面心立方晶格结构。极低的碳含量和提高了的Ti:C比率增加了结构的稳定性和最大的抗敏化性以及抗晶间腐蚀性。

  950C左右的低温退火保证了细晶结构。

  耐腐蚀性: 800H能耐很多腐蚀介质腐蚀。其较高的镍含量使其在水性腐蚀条件具有很好的抗应力腐蚀开裂性能。高铬含量使之具有更好的耐点腐蚀和缝隙腐蚀开裂性能。该合金具有很好的耐硝酸、有机酸腐蚀性，但是在硫酸和盐酸中的耐腐蚀性有限。除了在卤化物有可能发生点腐蚀外，在氧化性和非氧化性盐中有很好的耐腐蚀性。在水、蒸气以及蒸汽、空气、二氧化碳的混合物中也具有很好的耐腐蚀性。

  1.Excellent corrosion resistance in aqueous media up to 500°Cextremely high temperatures.

  2.Good resistance to stress corrosion.

  3.Good process ability.

  Metallographic structure: Face-centered cubic lattice structure.Extremely low carbon content and increased Ti: C ratio increase structural stability and maximum resistance to sensitization and resistance to intergranular corrosion.

  Low temperature annealing around 950C ensures a fine-grained structure.

  Corrosion resistance: 800H is resistant to many corrosive media. Its higher nickel content makes it resistant to stress corrosion cracking in aqueous corrosion conditions. The high chromium content makes it better resistant to pitting and crevice corrosion cracking. The alloy has good resistance to the corrosion of nitric acid and organic acids, but has limited corrosion resistance in sulfuric acid and hydrochloric acid. In addition to the possibility of pitting corrosion in halides, it has good corrosion resistance in oxidizing and non-oxidizing salts. It also has good corrosion resistance in water, steam and mixtures of steam, air and carbon dioxide.
