Characteristic as below:

  • GB NS333 is a omnipotent of nickel, chromium and molybdenum mixed alloy, with better corrosion resistance performance than other alloys, for example, Hastelloy C276 alloy, C4 alloy and 625 alloy. HY HC have a good resistance performance to pitting, crevice corrosion and stress corrosion cracking,  have excellent inoxidability water medium performance, including the wet-chlorine, nitric acid or oxidizing acid mixed acid with chloride ion. Meantime, HY HC possesses perfect resistance to reduction and oxidation of processing enviroments, then it can be used in some complicated environment or with many different manufacture target factory depend on the omnipotent performance. HY HC possess prominent resistance performance to different chemical environments, including strong oxidizing matter,such as iron chloride, copper chloride, chlorine, heat pollution liquid(organic and inorganic), formic acid, acetic acid, acetyl oxide, sea water and salting liquid and so on.

GB NS333 Metallurgical structure:

  • GB NS333 is face-centered cubic lattice structure.  

GB NS333 Corrosion resistance:

  • GB NS333 alloy suit for many kinds of chemical process industry which contain the oxidizing medium and reductant. High molybdenum and chromium content make it can resist the chloride corrosion, and tungsten make this corrosion resistance better. HY HC is one of a few material that can resist the corrosion of moist chlorine, hypochlorite and chlorine dioxide, this alloyhave prominent corrosion resistanceto high concentration chlorate( iron chloride and copper chloride)

 GB NS333 Application field:

  • GB NS333 is widely used in the chemical field and petrifaction field, such as the element of chloride organic and catalyze system. This material especially suit for high temperature environments, impure inorganic acid and organic acid (such as formic acid and acetic acid), sea-water corrosion environments.

 GB NS333 Other application field:

  1. Acetic acid/acetyl oxide

  2. Acid dipping

  3. Cellophane paper manufactures

  4. Chloride system

  5. Complicated mixed acid

  6. Electrogalvanizing groove roller

  7. Expansion bellows

  8. Flue gas washer system

  9. Geothermal well
