| 800H Characteristic: | 800H is the face-centered cubic lattice structure, very low carbon content and increased Ti:C rate improve the stability of the structure, anti-allergy, and anti-intergranular corrosion. Low temperature annealing around 950ºC ensure the fine grain structure. |
| 800H can not be corroded in many kinds of media. Its higher nickel content made it have good stress corrosion resistance cracking properties in the water corrosion condition. High chromium content made it better resistance to pitting and crevice corrosion cracking. This alloy can resist nitric acid and organic acid, but it is not so fine in the sulfuric acid and hydrochloric acid. 800H have good corrosion resistance to both oxidation and non-oxidizing salt, but maybe a little pitting in halide, and also excellent properties in the mixture of water, smoke, steam, air and carbon dioxide. |

| Application range and field | 1.Nitrate condenser---Corrosion resistance of Nitric acid 2.Steam heating pipes--Very good mechanical properties 3.Heat up element tube--Very good mechanical properties For the application of up to 500ºC environment, alloy state supplies change to annealing. |
