Hastelloy C4 NiMo16Cr16Ti N06455 Factory | High Corrosion Resistance

Hastelloy C-4 alloy is an austenitic low-carbon nickel-molybdenum-chromium alloy. The main difference from other early-developed alloys of similar chemical composition is its low carbon, silicon, iron, and tungsten content. Such a chemical composition makes it exhibit excellent stability at 650-1040°C, improves the ability to resist intergranular corrosion, and can avoid edge line corrosion sensitivity 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. The characteristics of HastelloyC-4 ●Excellent corrosion resistance to most corrosive media, especially in the reduced state. ●Excellent local corrosion resistance among halides. Hastelloy C-4 Metallographic Organization Structure Hastelloy C-4 alloy has a face-centered cubic lattice structure, and its chemical composition ensures metallographic stability and sensitization resistance. Hastelloy C-4 process performance and requirements 1. Do not touch sulfur, phosphorus, lead and other low melting point metals during the heat treatment process, otherwise the alloy will become brittle. Care should be taken to remove 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 temperature of the electric furnace can be accurately controlled 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 of Hastelloy C-4 alloy ranges from 1080°C to 900°C, and the cooling method is water cooling or other rapid cooling methods. In order to ensure the best anti-corrosion performance, solution heat treatment should be carried out after thermal processing. Hastelloy C-4 Chemical composition %
