Physical and chemical properties
Hastelloy C-4 alloy is an austenitic low carbon nickel-molybdenum-chromium alloy. The main difference between Nicrofer 6616 hMo and other earlier developed alloys of similar chemical composition is the low carbon, silicon, iron, and tungsten content.
Such a chemical composition enables it to exhibit excellent stability at 650-1040°C, improve resistance to intergranular corrosion, and avoid edge-line corrosion susceptibility and weld heat-affected zone corrosion under appropriate manufacturing conditions.
Alloys are used in flue gas desulfurization systems, pickling and acid regeneration plants, acetic acid and agrochemical production, titanium dioxide production (chlorine method), electrolytic plating, etc.
Hastelloy C-4 (Ni-Cr-Mo) has excellent thermal stability and toughness at high temperature, and has good resistance to stress corrosion cracking and oxidizing atmosphere at high temperature. Suitable for all kinds of hot mineral acids, chlorine-containing media, acetic acid, acetic anhydride, seawater and brine solutions and other corrosive substances.
Hastelloy C-4 Operating Temperature Approx: -200 to +400°C
Main features: good tissue stability, can be used directly after welding.
Application example: wet chlorine, hypochlorous acid, hydrochloric acid, chloride device.
Hastelloy C-4 process performance and requirements:
1. Do not touch sulfur, phosphorus, lead and other metals with low melting point during heat treatment, otherwise the alloy will become brittle. Attention should be paid to removing dirt such as marking paint, temperature indicating paint, colored crayons, lubricating oil, fuel, etc.
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 accurately control the temperature and the furnace gas is clean. If the gas of the gas stove is pure enough, you can also choose.
2. The hot working temperature range of Hastelloy C-4 alloy is 1080℃～900℃, and the cooling method is water cooling or other rapid cooling methods.
To ensure the best corrosion resistance, solution heat treatment should be carried out after hot working.
