Wrought nickel-base superalloy NS3203

Wrought nickel-base superalloy NS3203
NS3203 alloy Equal material: UNS N10675, 2.4600, Hastelloy B-3
NS3203 alloy is nickel molybdenum alloy as a new member of the family, it is for any temperature and concentration of hydrochloric acid has excellent corrosion resistance. At the same time it to sulfuric acid, acetic acid, formic acid, phosphoric acid and other oxidizing medium also has good corrosion resistance. And, because of its chemical composition adjustment, its thermal stability compared to the original NS3203 alloy has improved significantly. To point NS3203 corrosion, stress corrosion cracking, corrosion and welding heat affected zone, etc all have high corrosion resistance.

NS3203 Application:
NS3203 alloy can be used in the previous 2 B is all purposes. As with NS3203 is not recommended to trivalent iron salts and environment of the existence of bivalence copper salt, because these salt can quickly cause corrosion damage. When hydrochloric acid comes into contact with the iron and copper, will react to generate trivalent iron salts and bivalence copper salt.
NS3203 alloy Specifications:
Forgings, bar, sheet, strip, ring parts, wire, bolt, spring, such as negotiating supply, according to the customer request production
NS3203 Heat treatment:
Unless the customer special requirements, all NS3203 alloy forgings are solid solution heat treatment state supply. NS3203 - the temperature of the alloy is 1065 ℃ and then quenched quickly. Sheet or wire for bright annealing, the heating temperature is 1150 ℃, then cooling in the hydrogen.
NS3203 Physical properties:
NS3203 Alloy density: 2.1 to 9.22 g/cm3
NS3203 Melting point: 1418 degree
NS3203 Hardness: 2.5 HB94
NS3203 alloy Mechanical properties of the minimum 2.8

NS3203 Alloy has the following features:
1. The excellent corrosion resistance of reductive environment.
2. Excellent resistance to corrosive medium concentration of sulfuric acid and much non oxidizing acid.
3. Good resistance ability of various kinds of organic acid corrosion.
NS3203 Scope of application areas are:
NS3203 widely used in the chemical, petrochemical, energy production and has been widely used in pollution control areas, especially in the sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid, and other industries.
