The chemical composition in the 650-1040 ℃ show excellent stability, improve the ability of resistance to intercrystalline corrosion, under the condition of appropriate manufacturing can avoid the edge line corrosion sensitivity and weld heat affected zone of corrosion.
Hastelloy c-4 is characterized by:
Excellent corrosion resistance to most corrosive media, especially in reduction state.
Excellent local corrosion resistance in halides.
Hastelloy c-4 mechanical properties:
The minimum values in the table below are the vertical and horizontal measured data of the samples with the standard size and specification (solid solution treatment state). The properties of products with special specifications and special materials can be customized according to customers' requirements.
Hastelloyc-4iso-v notch test:
Mean 120J/cm2 room temperature
120 j/cm2-196 ℃ or higher
Hastelloy c-4 metallographic structure:
Hastelloy c-4 is a face centered cubic lattice structure, whose chemical composition ensures metallographic stability and resistance to sensitization.
The high content of molybdenum and chromium enables Hastelloy c-4 alloy to resist corrosion by a variety of chemical media, including reducing media, such as phosphoric acid, hydrochloric acid, sulfuric acid, chlorine gas, organic or inorganic chlorine-containing media.
Because of its high nickel content, Hastelloy c-4 is effectively resistant to stress corrosion cracking caused by chlorine, even in hot chloride solutions.

Hastelloy c-4 processing and heat treatment:
Hastelloy c-4 alloy can be manufactured and processed by traditional manufacturing process.
HastelloyC - 4 heating:
Always keep the workpiece clean and free from pollution before and during heat treatment.
Do not touch sulfur, phosphorus, lead and other low melting point metals during heat treatment, otherwise Nicrofer 6616 hMo alloy will become brittle, attention should be paid to remove such dirt as marking paint, temperature indicating paint, colored crayons, lubricating oil, fuel and so on.
The lower the sulfur content in the fuel, the better. The sulfur content in natural gas should be less than 0.1%, and the sulfur content in heavy oil should be less than 0.5%.
Electric furnace heating is a better choice, because the electric furnace can be accurate temperature control, clean furnace gas.
If the furnace gas is pure enough, you can also choose.
The furnace gas of heating furnace should be neutral to micro reductive. The fluctuation of furnace gas between oxidizing and reductive should be avoided. The heating flame cannot directly burn to the workpiece.
Hastelloy c-4 hot working:
Hastelloy C - 4 hot working temperature range of 1080 ℃ ~ 900 ℃, the cooling way for fast cooling water or other way.
In order to ensure the best anti-corrosion performance, the solution heat treatment should be carried out after hot processing.
Hastelloy c-4 cold working:
When cold working, the workpiece should be in the state of solid solution heat treatment, and the machining hardening rate of Hastelloy c-4 is greater than that of austenitic stainless steel, so it is necessary to select the processing equipment.
There should be intermediate annealing during cold rolling.
If the deformation of cold rolling is more than 15%, the workpiece needs to be treated with secondary solid solution.
Hastelloy c-4 heat treatment:
Hastelloy C - 4 solid solution treatment temperature range is 1050 ℃ ~ 1100 ℃.
For materials with a thickness of less than 1.5mm, the recommended cooling method is water quenching or rapid air cooling to obtain the maximum corrosion resistance.The workpiece must be kept clean during heat treatment.
Hastelloy c-4's surface oxides and slag around the weld have a stronger adhesion than stainless steel, and fine steel is recommended
Grinding by crystal sand belt or fine crystal grinding wheel.
Before acid pickling with HNO3/HF mixed acid, the oxide film must be sandblasted or polished to break up.
Hastelloy c-4 is machined in an annealed state.
Since the machining hardening of Nicrofer 6616 hMo is relatively high, it is advisable to use low cutting speed and heavy feed for machining before driving into the surface layer of cold hardening.
Hastelloy c-4 welding:
Hastelloy c-4 can be used in a variety of welding processes, such as tungsten inert gas welding, plasma arc welding, manual subarc welding, metal inert gas welding, fusion inert gas welding.
Pulse arc welding is preferred.
It has been widely used in the chemical and petrochemical fields, such as in the components and catalytic systems in contact with organics containing chloride.
This material is especially suitable for high temperature, mixed with impurities of inorganic acids and organic acids (such as formic acid and acetic acid), seawater corrosion environment.
Other application areas:
Pulp and paper industries, such as cooking and bleaching vessels
Washing tower, reheater and wet steam fan in FGD system
Equipment and components operating in an acidic gas environment
Reactor for acetic acid and acid products
Sulphuric acid condenser
Methylene diphenyl isocyanate (MDI)
Production and processing of impurity phosphoric acid
