Hastelloy C-4 Nickel Based tube
Hastelloy C-4 Nickel Based tube is an advanced nickel - chromium - molybdenum alloy. It is designed to resist extreme corrosive environments. The alloy has a nickel (Ni) base. It contains about 16% chromium (Cr) and 15 - 17% molybdenum (Mo). It also has some trace elements like iron (Fe) and titanium (Ti).
Hastelloy C-4 Nickel Based tube has optimized components. It has lower carbon content. It removes tungsten and adds titanium to stabilize. This improves its thermal stability and resistance to sensitization. It can be used in high - temperature and highly corrosive media environments.
Hastelloy C-4 Nickel Based tube is widely used in extreme corrosive environments. It is used in chemical pickling equipment, flue gas desulfurization systems, nuclear waste treatment pipes and pharmaceutical high - purity media conveyance.
Hastelloy C-4 Nickel Based tube has excellent resistance to chloride stress corrosion. It also has high - temperature stability and good weldability. It is a long - life solution in demanding industrial fields like energy and environmental protection. It can greatly reduce maintenance costs.
Features of Hastelloy C-4 Nickel Based tube
Excellent corrosion resistance: Hastelloy C-4 Nickel Based tube performs well in oxidizing and reducing acids (like hydrochloric acid and sulfuric acid), halides (including chloride stress corrosion cracking) and strong oxidizers (like hypochlorites). It is especially suitable for complex media with impurity ions.
High - temperature stability: Compared with the early C - 276 alloy, C - 4 has stronger resistance to grain - boundary precipitation in the range of 650 - 1040℃. It reduces the tendency of embrittlement after welding or heat treatment.
Forming and welding performance: Hastelloy C-4 Nickel Based tube has excellent cold and hot formability. It can be welded by common methods like TIG and MIG. No solution treatment is needed after welding.
Applications of Hastelloy C-4 Nickel Based tube
Chemical industry: Hastelloy C-4 Nickel Based tube is used to make pickling equipment, reactors and heat - exchanger pipes. It deals with corrosive fluids containing chloride ions or organic acids.
Environmental engineering: Hastelloy C-4 Nickel Based tube is used in components of flue gas desulfurization (FGD) systems. It resists erosion from sulfur dioxide and acidic condensate.
Nuclear and energy: Hastelloy C-4 Nickel Based tube is used in waste - acid recovery pipes of nuclear fuel reprocessing plants and in high - chloride environment pipelines of offshore oil and gas platforms.
Pharmaceutical industry: Hastelloy C-4 Nickel Based tube is used in high - purity - medium conveyance systems. It prevents metal - ion contamination.
