Characteristics & Properties of Hastelloy C-4
Hastelloy C-4 (UNS N06404) is a high-performance corrosion-resistant alloy of the nickel-chromium-molybdenum (Ni-Cr-Mo) series, developed by the American Hastelloy Alloy Company (Haynes International), and is a low-carbon titanium stabilized improved version of the Hastelloy C series. Hastelloy C-4 plate is an engineering material designed for high-temperature corrosion resistance. Its titanium stabilization + ultra-low carbon composition solves the sensitization problem of traditional nickel-based alloys. It is particularly suitable for welding parts and high-temperature and highly corrosive environments, and is irreplaceable in the fields of chemical industry, energy, etc.
Corrosion resistance:
Excellent resistance to chloride stress corrosion cracking (SCC).
Resistant to strong oxidizing media (such as nitric acid, chromic acid) and reducing media (such as sulfuric acid, hydrochloric acid).
Resistant to corrosion such as wet chlorine, hypochlorite, chlorine dioxide, etc.
Thermal stability:
No harmful phase precipitation in the range of 650-1040℃, avoiding intergranular corrosion.
Mechanical properties:
Good high temperature strength, suitable for high temperature and high pressure environment.
Good plasticity and toughness, easy to process and shape.
Typical application areas
Chemical industry: reactors, heat exchangers, piping systems (especially chloride ion environments).
Environmental engineering: flue gas desulfurization (FGD) systems, wastewater treatment equipment.
Petroleum and natural gas: acidic oil and gas extraction (resistant to H₂S and CO₂ corrosion).
Pharmaceutical industry: production equipment for strong acid media.
Nuclear industry: corrosive media containers in nuclear fuel reprocessing.
Processing and welding
Hot processing: It is recommended to heat to 1100-1200℃ for forging or rolling, and avoid staying in the 700-900℃ range for a long time.
Cold processing: Intermediate annealing is required to eliminate stress, and the annealing temperature is usually 1120-1170℃.
Welding: Applicable to TIG, MIG, arc welding, etc., it is recommended to use matching welding materials (such as HC-4 welding wire). Generally, no heat treatment is required after welding.

Advanced Production:Hastelloy alloy pipe
Hastelloy C4 alloy is an all-around nickel-chromium-molybdenum-tungsten alloy with good resistance to pitting, crevice corrosion and stress corrosion cracking. It has excellent resistance to oxidative aqueous media, including wet chlorine, nitric acid or mixed acids of oxidizing acids containing chloride ions. At the same time, Hastelloy C4 alloy also has ideal resistance to reducing and oxidizing environments encountered in the process. Relying on this versatile performance, it can be used in some troublesome environments or in factories for a variety of production purposes.
Hastelloy C-4 Pipe Features
Hastelloy C4 alloy has an exceptional resistance to various chemical environments, including strong oxidizing substances, such as ferric chloride, cupric chloride, chlorine, thermally contaminated solutions (organic and inorganic), formic acid, acetic acid, acetic anhydride, seawater and salt solutions, etc. Hastelloy C4 alloy has the ability to resist the formation of grain boundary precipitation in the heat affected zone of welding, so that it can also be used in many chemical processes in the welding state.
Kualitas, pengiriman, inspeksi
Daxun conducts a series of quality assurance tests on Hastelloy C-4 pipes. These tests include flattening test, flaring test, ultrasonic flaw detection, crevice corrosion resistance test, mechanical property test, hardness test, material positive identification, and expansion test, etc. All these tests are designed to ensure that the Hastelloy C-4 pipes meet the requirements of the intended applications. During the production process, we meticulously measure the outer diameter, wall thickness, and surface quality of the products. Our standard delivery time is 5 – 7 days, and for special sizes, it is 15 – 20 days.
