Hastelloy

UNS: N06455

CORROSION RESISTANCE: Hastelloy C-4 alloy exhibits excellent corrosion resistance in a wide range of corrosive media, including sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid, formic acid, urea and hydrated salt solutions. It also resists chemical corrosion such as oxidation and sulfidation. The high molybdenum and chromium content makes it resistant to a wide range of chemical media, including reducing media such as phosphoric acid, hydrochloric acid, sulfuric acid, chlorine gas, and organic or inorganic chlorine-containing media. Due to its high nickel content, Hastelloy C-4 effectively resists stress corrosion cracking due to chlorine, even in hot chloride solutions.

Heat Resistance: Hastelloy C-4 alloy has good heat resistance and maintains its physical and chemical properties at elevated temperatures. It has a wide range of service temperatures, typically between -200°C and 315°C (it is also claimed to have a melting point of approximately 1427°C, or 2600°F).

Strength and Toughness: Hastelloy C-4 alloy has high strength and good toughness to withstand mechanical stresses and corrosive environments.

WELDABILITY: Hastelloy C-4 alloy has good weldability and can be welded by a variety of welding methods, including tig welding (GTAW), arc welding (GMAW), and brazing. Recommended filler metals include GTAW/GMAW Nicrofer S 6616 and others.

Oxidation Resistance: Hastelloy C-4 alloy has good oxidation resistance and is able to resist oxidative corrosion at high temperatures. Wear Resistance: Hastelloy C-4 alloy has a certain degree of wear resistance and is able to maintain its performance in abrasive environments.
