The minimum mechanical properties of the alloy at room temperature
Typical mechanical properties
1, the alloy has good malleability, forging heating temperature 1140 ℃, final forging 900 ℃
Nickel-molybdenum alloy Hastelloy B-3 has very low carbon and low silicon content and lowers the precipitation of carbon and other impurities in the HAZ, so the weld is also corrosion-resistant. Alloy Hastelloy B-2 has good corrosion resistance in reducing media, such as hydrochloric acid solutions of various temperatures and concentrations. In the medium concentration of sulfuric acid solution (or contain a certain amount of chloride ion) also has good corrosion resistance. At the same time can also be used for acetic acid and phosphate environment. Alloy materials have the best corrosion resistance only in the proper metallurgical state and pure crystalline structure.
Hastelloy B-3 alloy is suitable for all uses of previous B-2 alloys. Like B-2 alloys, B-3 is not recommended for use in the presence of trivalent and cupric salts as these salts will quickly Cause corrosion damage.When hydrochloric acid comes into contact with iron and copper, it will react with it to generate ferric and cupric salts.
